The J Chain ELISA kits listed below utilize specific antibodies for the plate-based assay of J Chain in various samples. J Chain is another term for the JCHAIN gene, which encodes the protein, joining chain of multimeric IgA and IgM in humans. It has been reported that J Chain plays a role in adaptive immune responses, among other functions. Structurally, the JCHAIN protein is described to be 159 amino acid residues in length and 18.1 kilodaltons in mass. It is known to be a secreted protein. This protein is known to be glycosylated. Other names for this target antigen include IGCJ, IGCJ, and IGJ.
There are J Chain ELISA kits that can detect a target at concentrations as low as 1.56 ng/mL and as high as 9000 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
