{"product_id":"nsj-c4b-antibody-complement-c4b-primary-antibody","title":"C4B Antibody \/ Complement C4B","description":"\u003cp\u003eThis gene encodes the basic form of complement factor 4, part of the classical activation pathway. The protein is expressed as a single chain precursor which is proteolytically cleaved into a trimer of alpha, beta, and gamma chains prior to secretion. The trimer provides a surface for interaction between the antigen-antibody complex and other complement components. The alpha chain may be cleaved to release C4 anaphylatoxin, a mediator of local inflammation. Deficiency of this protein is associated with systemic lupus erythematosus. This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. Varying haplotypes of this gene cluster exist, such that individuals may have 1, 2, or 3 copies of this gene. In addition, this gene exists as a long form and a short form due to the presence or absence of a 6.4 kb endogenous HERV-K retrovirus in intron 9.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFamily\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePrimary antibody\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eIn 1X PBS, pH 7.4, with 0.09% sodium azide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormat\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity purified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eHost Animal\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eClonality\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePolyclonal (rabbit origin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eIsotype\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit Ig\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWB, ELISA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Details\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWestern blot: 1:1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Note\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eTitration of the C4B antibody may be required due to differences in protocols and secondary\/substrate sensitivity.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eImmunogen\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eA portion of amino acids 655-684 from the human protein was used as the immunogen for this C4B antibody.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAliquot the C4B antibody and store frozen at -20oC or colder.
