Protein Concentration
25µg size is bottled at 0.2mg/mL concentration. 100 µg size is supplied at a lot-specific concentration.
Storage and Handling
Briefly centrifuge the vial upon receipt. An unopened vial can be stored at 4°C for up to 2 weeks, or at -20°C or below for up to six months. The protein may be further diluted to 0.1 mg/mL using 0.22 µm-filtered PBS buffer (pH 7.4). For long-term storage, the diluted stock solution should be aliquoted and stored at ≤ –70°C to minimize freeze-thaw cycles. If additional dilution is required, carrier proteins such as FBS or BSA should be added to maintain protein stability.
Background Information
CD269, also known as B-cell maturation antigen (BCMA), is a 27 kD single-pass transmembrane protein that contains one TNFR-Cys repeat in its extracellular domain. This protein is a critical factor for the long-term survival and maintenance of plasma cells and plays an essential role in B-cell maturation. CD269 is expressed by plasmablasts, plasma cells, and germinal center B cells, and it is primarily involved in regulating humoral immunity. The ligands for CD269 include BAFF (B-cell activating factor) and APRIL (A proliferation-inducing ligand). These ligands bind to CD269, initiating a signaling cascade that supports B-cell survival and plasma cell function. Additionally, the cytoplasmic domain of CD269 interacts with several members of the TRAF (tumor necrosis factor receptor-associated factor) family, which are important for transducing survival and proliferation signals within the cell. Due to its essential role in immune response regulation, CD269 is a key player in the development and functioning of plasma cells.
