product information

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. It has also been accepted as the bacterial cytoskeletal counterpart to eukaryotic microtubules. Synonymes: sifB, SulB.


KLH-conjugated synthetic peptide derived from known bacterial sequences of FtsZ including E.coli P0A9A6

Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 50 ĩl
Reconstitution For reconstitution add 50 ĩl of sterile water.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

Tested applications western blot (WB), immunofluorescence (IF)

application example

western blot detection of bacterial FtsZ protein using anti-FtsZ antibody

 5 µg of total protein from Synechocystis sp. (1), E.coli DH5a (2), E. coli (3),  extracted with Agrisera PEB extraction buffer were separated on  4-12% SDS-PAGE and blotted 1h to PVDF. Blots were blocked with Advance blocking reagent  for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 10 000 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 TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602) diluted to 1:25 000 in  for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturers instructions. Exposure time was 120 seconds.

western blot using anti-procaryotic FtsZ antibody

Total protein extract from E. coli CFT073: 8µg (1), 12µg (2), 16µg (3). Proteins were separated on 10% SDS-PAGE and blotted to PVDF. Blocked with 5 % non-fat milk in TBS-T for 1 hour. Blot was incubated in the primary antibody at a dilution of 1 :10 000 for 1 h at RT with agitation. Secondary antibody (anti-rabbit IgG, HRP conjugated, Agrisera, AS09 602) were diluted to 1 : 50 000 and blot was incubated for 1h at RT with agitation. Immunodetection was performed using ECL method for 3 min. Scan was made after 30 sec.
