Product Overview

Tag N/A
Host Species Human
Synonym IGCJ, JCH, Immunoglobulin J chain, IGJ.
Background Immunoglobulin J chain (IGJ) helps to link 2 monomer units of either IgM or IgA and also also helps to bind these immunoglobulins to secretory component. When it comes to IgM, the J chain-joined dimer is a nucleating unit for the IgM pentamer and in the case of IgA it induces larger polymers.
Description IGJ Human Recombinant expressed in E. coli is a single polypeptide chain containing 160a.a. (23-159) and having a molecular weight of 18kDa. IGJ is fused to a 23a.a. His-tag at N-terminus and purified by unique purification methods.
