    Ig κ light chain Antibody (2G5-14) is a mouse monoclonal IgG1 kappa light chain antibody that detects the Ig κ light chain protein of human origin by western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). Anti-Ig κ light chain antibody (2G5-14) is available as a non-conjugated format, providing researchers with a reliable tool for studying this critical component of the immune system. Ig κ light chain plays a vital role in forming immunoglobulins, which are essential for adaptive immune response. These immunoglobulins consist of two identical heavy chains and two identical light chains, forming a Y-shaped structure that enables antigen recognition and binding. Kappa light chain presence contributes to antibody diversity produced by B cells, allowing for effective response to various pathogens. Genes encoding κ light chain are located on chromosome 2, and their rearrangement during B cell development generates diverse antibody repertoire. Understanding Ig κ light chain function and significance advances immunological research and therapeutic strategies targeting immune responses.
