Detection of BLAME/SLAMF8 in U937 Human Cell Line by Flow Cytometry. U937 human histiocytic lymphoma cell line were treated for 18 hours with 20 ng/mL Recombinant Human IFN-gamma (Catalog # 285-IF) then stained with Human BLAME/SLAMF8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1907, filled histogram) or control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).

Western Blot Detection of Human BLAME/SLAMF8 antibody by Western Blot. View Larger

Detection of Human BLAME/SLAMF8 by Western Blot. Western blot shows lysates of HEK293T human embryonic kidney cell line either mock transfected, transfected with EGFP, or transfected with human BLAME. PVDF membrane was probed with 0.1 µg/mL of Goat Anti-Human BLAME/SLAMF8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1907) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for BLAME/SLAMF8 at approximately 32 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: BLAME/SLAMF8

BLAME (B-lymphocyte activator macrophage expressed), also known as SLAM family member 8, is a type I transmembrane protein that belongs to the CD2 subset of immunoglobulin superfamily cell receptors. CD2 family proteins function as adhesion molecules and modulators of immune responses (1, 2). Mature human BLAME consists of a 211 amino acid (aa) ECD that contains two Ig V-like domains, a 21 aa transmembrane segment, and a 31 aa cytoplasmic tail that lacks recognizable signaling motifs (3). Within the ECD, human BLAME shares 19%‑26% aa sequence identity with human 2B4, CD2, CD2F-10, CD48, CD58, CD84, CD229, CRACC, NTB-A, and SLAM. It shares 79% aa sequence identity with the ECD of mouse BLAME. BLAME is expressed on dendritic cells and IFN-gamma stimulated monocytes. Overexpression of BLAME in bone marrow cells leads to an increase in the peritoneal B1b population of B lymphocytes (3).
