Clone Number:

N/A

Cells from human cell line was subjected to specific growth factor treatment, and cell extracts were prepared. An equal amount of proteins from control and growth factor treated samples were examined for p53 protein levels using SDS-PAGE followed by immunoblotting blotting techniques. Anti- p53 was procured from Cell Signaling Technology, and the selection of antibody was based on information provided in antibody flyer.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Human whole-cell protein lysate

Primary Incubation

Dilution (1:1000) in 5% BSA prepared in 1x TBST, overnight incubation at 4 degree Celsius

Blocking Agent

5% skimmed milk prepared in 1x TBST

Secondary Incubation

Goat anti-rabbit IgG HRP Ab, dilution (1:4000) in 5% skimmed milk prepared in 1x TBST, 2hr at RT
