SKU:: 584936
Molecular Weight:: 59.6
Purity:: ≥85% (SDS-PAGE)
Storage Conditions:: -20°C
Supplier:: United States Biological
Format:: Supplied as a lyophilized powder from 20mM Tris-HCl, 0.5M sodium chloride, pH 8.0, 6% trehalose. Reconstitute with sterile ddH2O to a concentration of 0.1-1mg/ml.
Extra Details:: 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. Source: Recombinant protein corresponding to aa23-159 from human Immunoglobulin J chain, fused to MBP-Tag at N-terminal and 6X His-Tag at C-terminal, expressed in Baculovirus.
