Schematic representation based on the hypothetical pI and Mw of the p65 and p65 iso5 protein pattern on 2D-PAGE. The full length images of 2-DE are available in the “ ” file.

Article Snippet: Then the membranes were washed 2 times for 7′ with PBS 1×, Tween 20 0,1% and incubated for 1 h at room temperature in a milk solution containing anti-rabbit IgG-HRP secondary antibody (sc-2004 Santa Cruz) dilution 1:4000 when used NF-kB p65 (A) or NF-kB p65 (c-20) antibody and with anti-mouse m-IgGκ BP-HRP secondary antibody (sc-516102 Santa Cruz) dilution 1:4000 when used NF-kB p65 (G-8) antibody.
