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. -

Immunohistochemical analysis of paraffin-embedded human tonsil tissue labelling SLAMF7/CS1 with ab237730 at 1/800 dilution for 15 minutes at room temperature, followed by ready to use Goat Anti-Rabbit IgG H&L (HRP). Positive staining on human tonsil is observed. Counterstained with Hematoxylin. The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

Immunohistochemical analysis of paraffin-embedded human multiple myeloma tissue labelling SLAMF7/CS1 with ab237730 at 1/800 dilution for 15 minutes at room temperature, followed by ready to use Goat Anti-Rabbit IgG H&L (HRP). Mainly membranous staining on the human multiple myeloma is observed. Counterstained with Hematoxylin. The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).
