A. U-87 MG cells were transfected with pCMV-LIP, cross-linked and ChIP assay performed using antibody to C/EBPβ, normal mouse serum or no antibody. Lane 1 - molecular weight markers. B. Expression of C/EBPβ-LIP in A was verified by Western blot. C. U-87 MG cells were transfected with pCMV-LIP and pCMV-p65, cross-linked and ChIP assay performed using antibody to C/EBPβ, antibody to p65, normal mouse serum or no antibody. Lane 1 - molecular weight markers. D. Expression of p65 and C/EBPβ-LIP in C was verified by Western blot.
