Anti-methyl-Histone H3 (Lys4)

Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the 'beads on a string' structure. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine. Applications: Suitable for use in Western Blot, Chromatin Immunoprecipitation and Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot : 0.5-2ug/ul. Detects methylated histone H3 in acid extracted proteins from HeLa cells. HeLa acid extract and recombinant histone H3 were resolved by electrophoresis, transferred to nitrocellulose and probed with H5110-11F9 (0.5ug/ml). Proteins were visualized using a goat anti-rabbit secondary antidody conjugated to HRP and a chemiluminescence detection system. , Optimal dilutions to be determined by the researcher. Recommended Secodary Antibodies: I1904-39: IgG, X-Adsorbed (HRP) Pab Gt xRb , I1904-40A: IgG, H&L, X-Adsorbed (HRP) Pab Gt xRb I1904-46Q: IgG, H&L (HRP) Pab Gt xRb, Positive Control: HeLa cell extract , Storage and Stability:, May be stored at 4°C for short-term only.
