Produktbeschreibung

Immunogen: This antibody was purified from hybridoma (clone C14264) supernatant using protein A agarose. This hybridoma was established by fusion of mouse myeloma cell Sp2/0-Ag14 with Balb/c mouse splenocyte immunized with the protein fraction extracted from the mitotic chromosome.

Isotyp: IgG2b  (Passende Sekundärantikörper)

Klon: C14264

Beschreibung: The nucleosome is made up of four core histone proteins (H2A, H2B, H3 and H4) and is the primary building block of chromatin. The N-terminal tail of core histones undergoes multiple different post-translational modifications including acetylation, phosphorylation, ubiquitination, methylation, and ADP-ribosylation. These modifications occur in response to cell signal stimuli and have a direct effect on gene expression. Acetylation of histone H2B was suppressed to greater extent than that of the others, with histone H3 being relatively least affected. The analysis of acetylation status of each of the four lysine sites at the N-terminal tail of histone H2B revealed decreases consistent with those observed in the total acetylation patterns, with the K12 and K20 residues being markedly more affected than K5 and K15 residues.

Spezifität: This antibody reacts with Histone H2B (14kDa) on Western blotting. .
