Molecular Weight
This protein is fused is fused with 6 ×his tag at the C terminus, and has a calculated MW of 50.9 kDa (Asp23-Glu449, α chain 24.5kDa + β chain 27kDa). The recombinant rh CLUS / Clusterin (Asp23-Glu 449) was cleaved into α chain and β chain, which form a heterodimer linked by disulfide bonds. DTT reduced protein migrates as 34-37kDa bands in SDS-PAGE due to glycosylation, corresponding to the cleaved β chain, and α chain respectively.

Background Information
Native Apolipoprotein J (ApoJ), also named Clusterin, is a heavily glycosylated, 75-80 kDa disulfide-linked heterodimeric protein. Despite being cloned since 1989, no genuine function has been attributed to ApoJ so far. The protein has been reportedly implicated in several diverse physiological processes such as sperm maturation, lipid transportation, complement inhibition, tissue remodeling, and membrane recycling, cell-cell and cell-substratum interactions, stabilization of stressed proteins in a folding-competent state and promotion or inhibition of apoptosis. ApoJ gene is differentially regulated by cytokines, growth factors and stress-inducing agents. Clusterin is up- or down regulated on the mRNA or protein level in many pathological and clinically relevant situations including cancer, organ regeneration, infection, Alzheimer disease, retinitis pigmentosa, myocardial infarction, renal tubular damage, autoimmunity and others.

Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
