Anti-Histone H2B (C-terminus) Antibody

DETAILS

Form: Antigen Affinity Purified
Gene: H2BC3
Host: Rabbit
Rrid: AB_3068452
Type: Primary Antibody
Buffer: PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
Target: Histone H2B (C-terminus)
Isotype: IgG
Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Shipping: Blue Ice
Synonyms: HIST1H2BB, H2BFF, Histone H2B type1B, H2B/f
Clonality: Rabbit Polyclonal
Immunogen: Histone H2B synthetic peptide (coupled to carrier protein) corresponds to amino acids in the C-terminus of human histone H2B. This sequence is well conserved in rat, mouse, fish, and drosophila histone H2B, and has low homology to other histone family members.
Expiration: After date of receipt, stable for at least 1 year at -20°C.
Specificity: The antibody detects a 15 kDa* protein corresponding to the molecular mass of Histone H2B on SDS-PAGE immunoblots of human A431, Jurkat, HeLa, mouse C2C12, rat PC12, and A7r5 cells. The antibody also shows nuclear labeling in immunocytochemistry of methanol/acetone fixed cells.

Target Description: The nucleosome is a protein complex consisting of four core histones (H2A, H2B, H3, and H4). Two molecules of each histone forms an octamer that makes up the nucleosome. DNA wraps around repeating nucleosome units to generate chromatin structures. The structure of chromatin determines the accessiblity to transcription factors. Post-translational modification of the amino-terminal tail of histones in nucleosomes alters chromatin structure to promote or inhibit transcription. Complex alterations in acetylation, methylation, ubiquination, and/or phosphorylation determine the chromatin structural changes that occur during specific phases of the cell cycle or in response to cell stimuli. One mode of regulating histone H2B activity is through phosphorylation in the amino terminal region. Important sites of phosphorylation include Ser-14, Ser-32, and Ser-36. AMPK phosphorylates Ser-36 on histone H2B during cell stress leading to increased transcription and cell survival, while ectopic expression of an unphosphorylatable histone H2B during cell stress reduces transcription of AMPK-dependent genes and lowers cell survival.
