Anti-IGJ / Immunoglobulin J chain / JCHAIN

In 1X PBS, pH 7.4, with 0.09% sodium azide. Immunoglobulin J / IGJ / JCHAIN is a protein that is part of the immunoglobulin family, which is responsible for producing antibodies that help the body fight off infections. IGJ is specifically involved in the production and assembly of antibodies, making it a key player in the immune system's defense mechanisms. IGJ plays a crucial role in the immune response by facilitating the assembly of antibodies. When the body encounters a pathogen, such as a virus or bacteria, IGJ helps to bring together different components of antibodies to form a functional immune response. This process is essential for the body to effectively recognize and neutralize foreign invaders. A deficiency in IGJ can lead to impaired immune responses, making individuals more susceptible to infections. Protein function: 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 dimers and/or larger polymers. It also helps to bind these immunoglobulins to secretory component. [The UniProt Consortium]
