CD244 (Natural Killer Cell Receptor 2B4, NK Cell Activation-inducing Ligand, NAIL, NK Cell Type I Receptor Protein 2B4, NKR2B4, h2B4, SLAM Family Member 4, SLAMF4, Signaling Lymphocytic Activation Molecule 4, 2B4, h2B4)

The signaling lymphocyte-activation molecule family member 4 (SLAMF4), also known as 2B4, is an important regulator of Natural Killer (NK) cell activation. It is expressed on NK cells as well as on subsets of T cells and interacts with SLAMF2, causing the activation of both SLAMF4- and SLAMF2-expressing cells. Patients with systemic lupus erythmatosus have lower than normal levels of SLAMF4 expressed on their NK cells and monocytes, suggesting that SLAMF4 may play a role in this autoimmune disease.\n\nApplications:\nSuitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1-2ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\nDaudi Cell Lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
