Anti-H4 ( K20 [Me2] ) (HIST1H4A, H4/A, H4FA, Histone H4)

Histone proteins H3, H4, H2A, and H2B function as building blocks to package eukaryotic DNA into repeating nucleosome units that are folded in higher order chromatin fibers. The nucleosome is composed of an octamer containing a H3/H4 tetramer and two H2A/H2B dimers, surrounded by approximately 146 base pairs of DNA. A diverse and elaborate array of post-translational modifications including acetylation, phosphorylation, methylation, ubiquitination, and ADP-ribosylation occurs on the N-terminal tail domains of histones. Applications: Suitable for use in Immunohistochemistry, Flow Cytometry, Western Blot, Dot Blot and ELISA. Other applications have not been tested. , Recommended Dilutions: Dot Blot: 1:500, Western Blot: 1:1000, Immunohistochemistry (FFPE): 1:50-1:100, Flow Cytometry: 1:10-1:50, Optimal dilutions to be determined by the researcher.
