Blocking/Neutralizing: NFkB p65 [p Ser276] Inhibitor Peptide Set [NBP2-26505] - Effect of various p65-inhibitor peptides on binding of purified recombinant p65 protein to the DNA in vitro. Recombinant p65 protein (100 ng/sample) was incubated for 30 minutes with 50uM of various peptides in 0.025 ml and then assayed for DNA binding activity by EMSA (Please refer to Takada et al, 2004 for further details).
