CD229 Antibody (HLy 9.1.25) is a mouse monoclonal IgG1 kappa light chain antibody that detects CD229 protein of human origin by western blotting (WB), immunoprecipitation (IP), and flow cytometry (FCM). Anti-CD229 antibody (HLy 9.1.25) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. CD229, also known as T lymphocyte surface antigen Ly9 or lymphocyte antigen 9, is a type I membrane glycoprotein that plays a critical role in the adhesion processes between T lymphocytes and accessory cells through homophilic interactions. This interaction is essential for effective immune responses, as CD229 facilitates communication between immune cells, thereby influencing cytokine production and cytotoxic activity of lymphocytes and natural killer cells. CD229 is part of the CD2 subfamily within the immunoglobulin gene superfamily, which includes other important receptors such as CD2, CD48, CD58, CD84, CD244, and CD150. CD229 interacts with the SAP/SH2D1A protein, which is significant for the regulation of immune signaling pathways. CD229 expression occurs on mature B cells, T cells, thymocytes, and natural killer cells, highlighting CD229′s importance in the immune system′s functionality and response to pathogens.
