    Ig λ chain Antibody (Rs4) is a mouse monoclonal IgG1 light chain antibody that detects Ig λ chain in human samples through applications such as western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). Ig λ chain plays a crucial role in the immune response by forming part of the immunoglobulin structure, which is essential for recognizing and binding to antigens. Anti-Ig λ chain antibody (Rs4) targets proteins primarily located in the cytoplasm of B cells, where Ig λ chain associates with heavy chains to form functional antibodies. The presence of Ig λ chain is particularly important because this protein allows for the generation of diverse antibody specificities, enabling the immune system to effectively target a wide range of pathogens. Additionally, Ig λ chain expression can influence the overall antibody response, as different light chain isotypes can affect the stability and functionality of the resulting immunoglobulin. Ig λ chain monoclonal antibody (Rs4) serves as an invaluable tool for researchers studying B cell development and the mechanisms of antibody diversity, providing insights into the adaptive immune system′s ability to respond to various challenges.

    I am using Ig λ chain (Rs4): sc-51638 for immunofluorescence, what dilution of this antibody should I use?

    Asked by: Trav11
    Thank you for your question. We recommend a starting dilution of 1:50. However, optimal antibody concentration should be determined by titration. Please find our full immunofluorescence protocol here: https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining
