Whole cell extract (30 μg) was separated by 7.5% SDS-PAGE, and the membrane was blotted with BCL6 antibody [N2C1], Internal (GTX101338) diluted at 1:1000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody.

Various whole cell extracts (30 μg) were separated by 5% SDS-PAGE, and the membrane was blotted with BCL6 antibody [N2C1], Internal (GTX101338) diluted at 1:1000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody.

Cross-linked ChIP was performed with Raji chromatin extract and 5 μg of either control rabbit IgG or anti-BCL6 antibody. The precipitated DNA was detected by PCR with primer set targeting to PRDM1 or CD20.

BCL6 antibody immunoprecipitates BCL6 protein in IP experiments. IP Sample: Raji whole cell lysate/extract A : 30 μg whole cell lysate/extract of BCL6 protein expressing Raji cells B : Control with 3 μg of pre-immune rabbit IgG C : Immunoprecipitation of BCL6 by 3 μg of BCL6 antibody (GTX101338) 7.5% SDS-PAGE The immunoprecipitated BCL6 protein was detected by BCL6 antibody (GTX101338) diluted at 1 : 1000. EasyBlot anti-rabbit IgG (HRP) (GTX221666-01) was used as a secondary reagent.

Whole cell extract (30 μg) was separated by 7.5% SDS-PAGE, and the membrane was blotted with BCL6 antibody (GTX101338) diluted at 1:1000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody, and the signal was developed with Trident ECL plus-Enhanced.
