Relevance
SLAMF7 contains one Ig-like C2-type (immunoglobulin-like) domain. Isoform 1 mediates NK cell activation through a SAP-independent extracellular signal-regulated ERK-mediated pathway. It may play a role in lymphocyte adhesion. Isoform 3 does not mediate any activation. SAP can bind the cytoplasmic tail of isoform 1 when phosphorylated in the presence of Fyn (in vitro). SLAMF7 is expressed in spleen, lymph node, peripheral blood leukocytes, bone marrow, small intestine, stomach, appendix, lung and trachea. Expression was detected in NK cells, activated B-cells, NK-cell line but not in promyelocytic, B-, or T-cell lines. The isoform 3 is expressed at much lower level than isoform 1. There are three named isoforms. -

SLAMF7/CS1 was immunoprecipitated from 0.35 mg of IM-9 (human multiple myeloma B lymphoblast cell line) whole cell lysate with ab230945 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab230945 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
Lane 1: IM-9 whole cell lysate 10 μg (Input).
Lane 2: ab230945 IP in IM-9 whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab230945 in IM-9 whole cell lysate.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 8 seconds.
The expression profile observed is consistent with what has been described in the literature (PMID: 18451245; 11698418; 25312647), with the bands greater than 37 kDa predicted to be glycosylated SLAMF7/CS1.

Immunohistochemical analysis of paraffin-embedded human multiple myeloma tissue labeling SLAMF7/CS1 with ab230945 at 1/2000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Mainly cytoplasmic staining in human multiple myeloma (PMID: 26005365; PMID: 18451245) is observed. Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).
