    Immunogold TEM images of cyanobacterial cells from YNP samples.All cells were immunogold labelled by Rabbit anti-RuBisCO (large subunit, form I and II, AS03 037) at a dilution of 1000X. The gold particles are uniformly sized and dark, two examples are marked by red arrows in (A, B, C). (A) The distribution of immunogold particles tagging free RuBisCO in a cell lacking cyanophycin or carboxysomes. SiO2 around the cell is marked by a black arrow, these granules are bigger than gold particles. (B) The absence of immunogold particles in cyanophycin granules indicates the absence of RuBisCO. (C) Immunogold particles tagging RuBisCO in small inclusions suggest the presence of morphologically atypical carboxysomes. These inclusions are rare and are found in the same areas where large cyanophycin granules typically occur. Few gold particles outside the cell in (A, B, C) indicate a low level backgroung. Scale bars: 200 nm in (A, B), and 100 nm in (C).

    This antibody is especially suitable for quantifying of Rubisco in plant and algal samples.

    Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthetic organisms. It is demonstrably homologous from purple bacteria to flowering plants and consists of two protein subunits, each present in 8 copies. In plants and green algae, the large subunit (~55 kDa) is coded by the chloroplast rbcL gene, and the small subunit (15 kDa) is coded by a family of nuclear rbcS genes.

    Rubisco quantitation in plant and algal samples using Agrisera anti-RbcL global antibody and Rubisco protein standard

    Methodology: Plant samples are generally ground with liquid nitrogen in a mortar and pestle. The resulting powder is transferred to a plastic tube. Algal samples can be either concentrated by centrifugation or, preferably, by filtration onto glass fiber filters. Solubilization is performed in Agrisera protein extraction buffer (PEB, AS08 300) containing 0.1mg/mL PefaBloc SC (AEBSF) protease inhibitor (Roche). Disruption is most optimally obtained through flash freezing of the sample in liquid nitrogen alternated with thawing by sonication with a microtip. This process can be repeated depending on the toughness of the sample. The sample is adjusted to 50 mM dithiothreitol and heated to 70°C for 5 minutes. Samples are cooled and centrifuged briefly prior to electrophoresis.

    Optimal quantitation is achieved using moderate sample loads per gel lane, generally 0.5 to 2.5 ug total protein, depending on the abundance of the target protein.

    Electrophoresis and Immunoblotting: Once solubilized, the proteins can be separated electrophoretically in a number of systems. We obtain optimal results with the Invitrogen NuPAGE gel system using Bis-Tris 4-12% gradient gels. Proteins are separated in MES SDS running buffer according to the manufacturer’s recommendations at 200 V for 35 minutes. The gels are transferred to PVDF in the same apparatus, the SureLock XCell blot module, for 60 minutes at 30 V for a single gel or 80 minutes for a pair. Following transfer the blots are blocked with non-fat dry milk up to 10 % in TBS-T, for 1 h/RT with gentle agitation. The blot is incubated with primary antibody, usually at 1:25 000 to 1:50 000, for 1 h/RT (if extreme femtogram detection reagents are used) or in lower primary antibody dilution for less sensitivie reagents (mid picogram and lower).

    For quantitation a relatively high primary antibody: target protein ratio gives more reliable results than immunoblots at low ratios of primary antibody:target protein.

    The blot is washed extensively in TBS-T (twice briefly, once for 15 minutes and three times for five minutes). The blot is incubated with secondary antibody, for example goat anti-rabbit IgG horse radish peroxidase conjugated, AS09 602 (Agrisera), for 1h/RT. The blot is washed as above and developed with ECL detection reagents.

    Quantitation: When quantitated standards are included on the blot, the samples can be quantitated using the available software. Excellent quantitation can be obtained with images captured on the Bio-Rad Fluor-S-Max or equivalent instrument using Bio-Rad QuantityOne software. The contour tool is used to select the area for quantitation and the values are background subtracted to give an adjusted volume in counts for each standard and sample. Using above protocol linear standard curves are generated over 1-1.5 orders of magnitude range in target load. It is important to note that immunodetections usually show a strongly sigmoidal signal to load response curve, with a region of trace detection of low loads, a pseudolinear range and a region of saturated response with high loads. For immunoquantitation it is critical that the target proteins in the samples and the standard curve fall within the pseudolinear range. Our total detection range using this protocol spans over 2 orders of magnitude, but the quantifiable range is narrower.

    Application example

    western blot using anti-RbcL antibodies on Prochlorococcus sp.

    2 µg of total protein from (1-7) Prochlorococcus sp. extracted with Protein Extration Buffer, PEB (AS08 300), (8-11) Rubisco protein standard (AS01 017S) were separated on  4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following transfer for 1h/RT with agitation. Blots were incubated in the primary antibody at a dilution of 1: 20 000 for 1h at room temperature with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:50 000 for 1h/RT with agitation. The blots were washed as above and developed for 5 min with ECL detection reagent according the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad). There is a low level of a known RbcL cleavage product below the main band in some of the Prochlorococcus samples.

    Samples must be sectioned at 1 x 1 mm. 1)Fixation: Glutaraldehyde 0.5% + paraformaldehyde 2.5% in sodium phosphate buffer 0.1M pH= 7.2, 1 hour and 30 min. 2) 3 washes in sodium phosphate buffer 0.1M pH= 7.2 (15 min. each one).  3)Dehydratation and embedding:

    -35% Ethanol……30 min.
    -50% Ethanol……30 min.
    -70% Ethanol……30 min.
    -96% Ethanol……30 min.
    -100% Ethanol……30 min.
    -100% Ethanol……30 min.
    -100% Ethanol……30 min.

    -75% Ethanol + 25% LR White…… 1 hour
    -50% Ethanol + 50% LR White…… 1 hour
    -25% Ethanol + 75% LR White…… 1 hour
    -100% LR White…………………... 1 hour
    -100% LR White…………………... overnight.

    4) Polymerization: Oven 12-18 hours at 50ºC. For flat molds in continous flux of N2

    5) Block sectioning: Ultrathin sections (60-70nm) using a ultramicrotome. Ultrathin sections should be placed on formvar coated níkel grids.

     IMMUNOLABELLING

    1) Blocking: Place grids with sections into 30-μL drop of blocking buffer during 30 minutes. (Blocking buffer: phosphate-buffered saline (PBS) + 5% bovine serum albumin (BSA).

    2) Incubation: Incubate in drop of primary antibody, anti-RbcL (Rubisco form I and II, Agrisera) diluted 1:250 in blocking buffer. 3 hours at room temperature (could be extend to overninght).

    3) Rinse: Pass the grids through a series of drops of PBS + 1%BSA. Two or three changes during 5 minutes each one.

    4) Incubation: Incubate grids in 30-μL of secondary antibody gold-labelled (British BioCell International, 10nm), diluted 1:50 in blocking buffer during 1.5 hours at room temperature.

    5) Rinse: Pass the grids through a series of drops of PBS + 1%BSA. Two changes during 5 minutes each one.

    6) Rinse: Pass the grids through a series of drops of PBS. Two or three changes during 5 minutes each one.

    7) Rinse: Pass the grids through a series of drops of water (ultra-pure water must filtered 0.2 μm) . Four to five changes during 5 minutes each one, allowed to dry for later observation.

    8) Staining: The grids may be post-stained with uranyl acetate and lead citrate.

    I have been using this antibody for the past 7 years. It has worked wonderfully for me every time I tried. I have used it on cyanobacteria (including Trichodesmium), Diatoms, and Seagrasses, with and without the RbcL standard. i have several publication in which I used this antibody (and others by Agrisera). Publication for example: Levitan et al., 2010, Regulation of nitrogen metabolism in the marine diazotroph Trichodesmium IMS101 under varying temperatures and atmospheric CO2 concentrations, Environmental microbiology.Levitan et al., 2015, Remodeling of intermediate metabolism in the diatom Phaeodactylum tricornutum under nitrogen stress, PNAS

    samples used were thylakoids and leaf powder, 12% SDS gels for PAGE, 5 ug protein per lane or 7 ug/chlorophyll per lane (thylakoids), dilution 1:5000, the observed product at ca. 53 kDa, AB works well

    Weve been very happy with this antibody. We have been using it for both westerns and ELISAs, with great results. We work with sea water samples containing a mixed population of species of diatoms and other plankton.

    I am satisfied with this antibody from Agrisera. It gives clean results. We have used this antibody for western blot detection (diluttion 1:20 000).

    Im using the antibodies for the immunodetection on western blots with the fluorescent based licor odyssey system (with the IRDye secondary antibodies Donkey anti rabbit IgG 800CW and 680 (Licor)). Im analysing whole protein or chloroplasts protein extracts optained from Arabidopsis thaliana. Proteins were either precipitated with TCA/Aceton or directly solubilized with NP-40 in a tris-buffer. The only problem with the unprecipitated samples is that one gets a very strong backround in the 680nm channel due to the chlorophyll-fluorescence. The primary antibodies were diluted in TBS with 0,02% Sodiumazid according to the recommanded dilution (for ECL) in the data sheet and the membranes were incubated for 1 h at RT with agitation. The membranes are blocked with BSA in TBS and washed with TBS-T. Im reusing the diluted antibodies for up to 5 to 10 western blots without any significant loss of signal (diuluted antibodies are stored at 4C). The signals Im getting with the antibodies are very clear and hieghly specific, with only low (anti-Lhcb1 and 2) or nearly no (anti-RbcL and RA) unspecific binding. Usually, Im loading 10 g protein and seperate them on 10% Mini-gels. So far I had no problems with Agrisera-antibodies.

    The antibody worked excellent on a Guzmania hybrid (Bromeliaceae) in both dilutions, 1: 5000 and 1:10 000.
