Citrullinated Histone H2B Type 1-A is a citrullinated form of human histone H2B type 1-A (hTSH2B), a testis- and sperm-specific variant of the histone H2B protein that is encoded by H2BC1, previously known as HIST1H2BA.{53231,53236} hTSH2B shares 85% identity with human somatic H2B.1, with the majority of amino acid differences between hTSH2B and somatic H2B occurring at the N-terminal end of the protein.{53231} H2BC1 is expressed in testis, and protein levels of hTSH2B are elevated in early round spermatids, decreasing over the course of spermiogenesis, with hTSH2B present in approximately 20% of mature spermatozoa.{53231,53232} hTSH2B is enriched at promoter regions of genes important for sperm biology, capacitation, and fertilization and localizes to the basal nuclear area in mature spermatozoa.{53231,53233} When incubated in Xenopus egg extracts, hTSH2B-positive human sperm cells decondense more rapidly and have increased long nuclear axis lengths compared with hTSH2B-negative sperm cells.{53234} Mice lacking the genes encoding the murine homolog of hTSH2B (TH2B), as well as the histone variant TH2A (Th2a-/-Th2b-/- mice), are sterile and have spermatogenesis defects.{53235} This product contains purified histone H2B type 1-A (human, recombinant) (Item No. 11081) that has been modified with PAD4 enzyme, which is subsequently depleted by affinity chromatography. Cayman’s Citrullinated Histone H2B Type 1-A (human, recombinant) can be used for Western blot and ELISA applications.

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
