  • Application Examples
  • Application example
    western blot using anti-LhcSR1 antibodies

    10 ug of a total cell extract of Chlamydomonas reinhardtii: WT _P _HL_High CO2 (1), WT_P_HL (2),  Npq4_P _HL (3), were separated on Bolt® 4-12% Bis-Tris Plus Gels (precast) and blotted to PVDF using Bolt® transfer system for 1h . Blots were blocked with 5% BSA/milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 1h at RT 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 PBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602, Agrisera) diluted to 1:10 000 in for 1h at RT with
    agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was 10 seconds.

    Coomassie stained SDS-PAGE analysis of thylakoid membrane proteins from control and different-sized cell fractions of C. priscuii(A). Lanes of SDS-PAGE were loaded on an equal Chl basis. Values on the left indicate apparent molecular mass (kDa). B – Representative Western blots (B) and densitometric analysis (C) of polypeptides probed with antibodies raised against Cyt f, Lhcbm5, Lhcb4, and PsaA polypeptides in thylakoid membranes isolated from different-sized cell fractions of C. priscuii. Mean values ± SE were calculated from 3 independent experiments. The presented data were normalized to the relative abundance of the respective polypeptides in the control whole cell fraction.

  • Additional Information
  • Additional information (application): This antibody is also recognizing recombinant LHCSR1 overexpressed in E.coli as described in Perozeni et al. (2020).
  • Background
  • Background:

    LHCSR1 (Stress-related chlorophyll a/b binding protein 1) plays a role in an efficient enery dissipation process, called non-photochemical quenching (NPQ), in Chlamydomonas reinhardtii.

    Antibody works relatively good, but is a bit expensive for the amount (considering the high concentration that you need for a single Western Blot).
