    Ig κ chain Antibody (OX12) is a mouse monoclonal IgG2a kappa light chain antibody that detects Ig κ chain protein of mouse and rat origin by immunofluorescence (IF) and flow cytometry (FCM). Ig κ chain plays a crucial role in immune response, as one of two types of light chains that pair with heavy chains to form functional antibodies. The presence of κ light chain is essential for proper assembly and stability of immunoglobulins, which are vital for recognizing and neutralizing pathogens. In B cell development, rearrangement of immunoglobulin genes allows for a diverse repertoire of antibodies, enabling immune systems to respond effectively to a wide range of antigens. Ig κ chain is encoded by genes located on chromosome 2 in humans, and expression is tightly regulated during B cell maturation, ensuring each B cell produces a unique antibody specific to a particular antigen. Understanding Ig κ chain function and significance is important for research into immune responses and development of therapeutic antibodies. Anti-Ig κ chain antibody (OX12) serves as an invaluable tool for researchers studying these processes in mouse and rat models.

    How can Ig κ chain (OX12): sc-53079 mouse monoclonal antibody be used for double or triple staining, if the other primary antibodies are also raised in mouse?

    Asked by: Professor Griffin
    In this case, we recommend using a directly conjugated mouse monoclonal primary antibody. This antibody is available conjugated to phycoerythrin (sc-53079 PE) or fluoroscein (sc-53079 FITC).
