Anti-Histone H3 (BSA & Glycerol free)

Modulation of the chromatin structure plays an important role in the regulation of transcription in eukaryotes. The nucleosome, made up of four core histone proteins (H2A, H2B, H3 and H4), is the primary building block of chromatin (1). The N-terminal tail of core histones undergoes different posttranslational modifications including acetylation, phosphorylation and methylation (2-4). These modifications occur in response to cell signal stimuli and have a direct effect on gene expression. In most species, the histone H2B is primarily acetylated at lysines 5, 12, 15 and 20 (4,5). Histone H3 is primarily acetylated at lysines 9, 14, 18 and 23 (2,3). Acetylation at lysine 9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (2,3). Phosphorylation at Ser10 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis (6). Applications: Suitable for use in Western Blot, Immunohistochemistry and Immunocytochemistry. Other applications have not been tested. Recommended Dilution: Western Blot: 1:1000 , Immunohistochemistry (Paraffin): 1:25 , Immunocytochemistry (IF): 1:50, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
