IsotypeIg
HostRabbit
ApplicationWB
Additional InformationFunction: Non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes. C4A isotype is responsible for effective binding to form amide bonds with immune aggregates or protein antigens, while C4B isotype catalyzes the transacylation of the thioester carbonyl group to form ester bonds with carbohydrate antigens.
Cellular Location: Secreted.
Tissue Location: Complement component C4 is expressed at highest levels in the liver, at moderate levels in the adrenal cortex, adrenal medulla, thyroid gland,and the kidney, and at lowest levels in the heart, ovary, small intestine, thymus, pancreas and spleen. The extra-hepatic sites of expression may be important for the local protection and inflammatory response.
Reconstitution and StorageMaintain refrigerated at 2-8C for up to 2 weeks. For long term storage store at -20C in small aliquots to prevent freeze-thaw cycles.
ImmunogenThis C4B antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 655-684 amino acids from the Central region of human C4B.
PurificationThis antibody is purified through a protein A column, followed by peptide affinity purification.
Predicted Homology Based on Immunogen SequenceHuman
ConcentrationApproximately 0.5mg/ml. Actual concentration varies with each lot.
Intended UseFor research use only and not for use in diagnostic or therapeutic procedures.

NCBI Gene Id720
Protein NameComplement C4-A
Description of TargetThis 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.
