Western BlotImmunofluorescence
YesYes

Material
The anti-tubulin antibody (Cat. # ATN02) is an affinity purified sheep polyclonal antibody that reacts to alpha and beta tubulin. The immunogen used for antibody production was a mixture of purified tubulins and therefore the antibody has broad species cross reactivity from yeast to humans. Porcine extract (Cat. # EXT03) is included as a positive control and ATN02 identifies a characteristic tubulin band at 55 kD on Western blots (see Fig. 1).  ATN02 is supplied as a lyophilized white powder.

 

Example Results


Figure 1. Western blot analysis of anti-tubulin antibody.  Protein samples were separated by electrophoresis and transferred to PVDF membrane as described in the methods.  ATN02 antibody was diluted to 50 0 ng/ml (1:1000) for Western blot analysis.  Tubulin was detected in 10 µg of bovine brain extract (see arrow at 55 kD).  Molecular weight markers are from Invitrogen. 

Figure 2. Western blot of cell extracts probed with anti-tubulin polyclonal antibody (Cat. # ATN02). Chemiluminescence detection of tubulin in extracts of Drosophila S2 cells (50 µg, lane 1) Xenopus A6 cells (50 µg, lane 2), mouse Swiss 3T3 cells (50 µg, lane 3), rat NRK cells (50 µg, lane 4), human HeLa cells (50 µg, lane 5), and bovine brain (50 µg, lane 6) at 55 kD (see arrow).  The blot was probed with a 500 ng/ml (1:1000) dilution of ATN02.

Figure 3. Immunofluorescence image of mouse Swiss 3T3 cells stained with Anti-Tubulin  polyclonal antibody (Cat. # ATN02). Swiss 3T3 cells were grown to semi-confluency and fixed with methanol. Immunofluorescence staining using 2.5 µg/ml (1:200 dilution) ATN02 antibody is shown (red). The primary antibody was detected with a 1:500 dilution of anti-sheep rhodamine conjugated antibody. DNA (blue) was stained with 100 nM DAPI in PBS. Photograph was taken with a 100X objective lens.

Microtubules are pseudocolored in green and chrmosomes in red.
