This antibody recognizes 7 isoforms of SP100, including SP100-HMG, SP100-A, SP100-B, and SP100-C. This antibody detects a 20 kDa protein of unknown identity in some cell lines.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro382 of human SP100 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nSpeckled protein 100 kDa (SP100), also known as SP100 nuclear antigen, was first identified as an antigen reactive with antibodies from patients with autoimmune disorders (1,2). The nuclear distribution of SP100 predominantly colocalizes with promyelocytic leukemia-nuclear bodies (PML-NBs) (3), which function as structures that regulate several diverse cellular functions, including gene regulation, DNA-damage responses, and apoptosis (4-6). This protein contains several isoforms, and the major isoform SP100-A has a calculated molecular weight of 54 kDa but exerts aberrant electrophoretic mobilities in SDS-polyacrylamide gel electrophoresis of approximately 100 kDa (1,2). SP100 has also been shown to undergo extensive post-translational modifications (PTM), including phosphorylation, ubiquitination, and SUMOylation. Moreover, PML-NBs play an important role in the PTM status of SP100, since they are thought to serve as hotspots for SUMOylation reactions, and PML depletion reduces SP100 SUMOylation (7-9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp686E07254; FLJ00340; FLJ34579; Lysp100b; nuclear antigen Sp100; Nuclear autoantigen Sp-100; Nuclear dot-associated Sp100 protein; SP100; SP100 nuclear antigen; SP100-HMG nuclear autoantigen; Speckled 100 kDa\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 80, 90, 130\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799913255081,"sku":"80075S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-80075s","provider":"Iright","version":"1.0","type":"link"}
