Anti-HIST1H1B antibodies are protein reagents that detect specific antigens. The HIST1H1B antigen is another term for the human protein H1.5 linker histone, cluster member, encoded by the H1-5 gene. The protein is known to function in chromatin organization and muscle organ development, among other biological roles. Canonically, it has an amino acid length of 226 residues and a mass of 22.6 kilodaltons. Its subcellular localization is in the nucleus and chromosomes and it is ubiquitously expressed across many tissue types. The HIST1H1B protein is a member of the Histone H1/H5 protein family. Other alias names for HIST1H1B include H1, H1.5, and H1B. Some HIST1H1B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
