Whole cyanobacterial (Anabaena PCC 7120) FtsZ protein, UniProt: Q3MC27 overexpressed in E.coli.
44.5 | 50 kDa
Phaeodactylum tricornutum, Prochlorococcus sp.
Total protein samples (5 or 10 µg) from: Arabidopsis thaliana, leaf (1), Synechocystis 6803 motile (2), Synechocystis 6803 GT (glucose tolerant strain) (3), Synechococcus elongates 7942 (4), Marker - Pierce™ Prestained Protein MW Marker (kat #26612) were extracted with buffer (10mM Tris HCl, pH 8.0, 0.5% LDS, 4% glycerol, 0.1 mM EDTA ) were mixed with sample buffer and denatured for 5 min at 95°C. Samples were separated on 10% SDS -PAGE and blotted 1h to nitrocellulose membrane (Amersham Protran) using sem i-dry transfer (Bio -Rad) in standard transfer buffer in presence of 10% methanol. Transfer of proteins to the membrane was checked using 0,5% Ponceau S staining before the blocking step. Blots were blocked in buffer (2% low -fat milk in 1xPBS, 0,1% Tween) for 1h at room temperature (RT) with agitation. Blots were incubated in the primary antibody at a dilution of 1: 1000 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 ( goat anti -rabbit IgG, AS09 602, Agrisera) diluted to 1:30 000 for 1h at RT with agitation. The blot was washed as above and developed for 5 min with chemiluminescence detection reagent and ChemiDoc detection system.

To detect FtsZ protein in higher plants following antibodies are recommended:
AS09 413 | Anti-FtsZ1 and 2 | Plant cell division protein FtsZ1 and FtsZ2, rabbit antibodies
AS13 2651 | Anti-FtsZ2 | Plant cell division protein ftsZ2, rabbit antibodies
Immunofluorescence has been done by labelling Synechococcus elongatus cells at 30°C for 2 hours with FtsZ antibodies diluted to 1: 500 in blocking buffer. Detection images can be found in Kabeya et al (2010).
This product can be sold containing ProClin if requested.
FtsZ (cell division GTPase) is a well characterized protein of the bacterial cell division apparatus. This protein accumulates early in dividing cells, and has a crucial role during septum formation in most bacteria as well as in chloroplasts. It has also been accepted as the bacterial cytoskeletal counterpart to eukaryotic microtubules.
