Tiam1 (C-16)

Catalog Number:

sc-872

Present study was conducted to test the role of specific treatment on Tiam1 expression in human endothelial cells. Growth arrested endothelial cells were given to specific treatments, protein extracts were made, resolved in 7.5% SDS PAGE, and western transferred in nitrocellulose membrane. Blot was probed with Tiam1 antibody to detect Tiam1 in protein samples. Santa Cruz Biotechnology antibody flyer has shown very good detection of Tiam1 by western blot so, the antibody was purchased.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Human endothelial cell extract

Primary Incubation

Dilution (1:500) in 5% skimmed milk prepared in TBST, overnight incubation at 4 degree Celsius

Blocking Agent

5% skimmed milk prepared in TBST

Secondary Incubation

Dilution (1:4000) in 5% skimmed milk prepared in TBST, 1hr at RT

Tertiary Incubation

None

Detection

Enhanced chemiluminiscent detection in X-Ray film

Results Summary

Just opposite to whatever is shown in Santa Cruz Biotech antibody flyer. We got a lot of non specific bands in human endothelial cells. Antibody passed to detect Tiam1 band at almost 200 kDa molecular weight. There was no or very little positive effect specific treatment on Tiam1 expression observed.

Additional Notes

None
