Recombinant Human Immunoglobulin J chain(JCHAIN)

Code CSB-EP011337HU
Product Type Recombinant Protein
Size US$1726
Uniprot No. P01591
Relevance Serves to link two monomer units of either IgM or IgA. In the case of IgM, the J chain-joined dimer is a nucleating unit for the IgM pentamer, and in the case of IgA it induces larger polymers. It also help to bind these immunoglobulins to secretory component.
