SLAMF6 Protein, Human, Recombinant (His Tag)

Product Specifications

Background

SLAM family member 6, also known as Activating NK receptor, NK-T-B-antigen, NTB-A, SLAMF6, KALI and Ly18, is a single-pass type I membrane protein that belongs to the CD2 subfamily of the immunoglobulin superfamily. SLAMF6 / Ly18 contains one Ig-like (immunoglobulin-like) domain. It is expressed by all (resting and activated) natural killer cells (NK), T- and B-lymphocytes. SLAMF6 / Ly18 triggers cytolytic activity only in natural killer cells (NK) expressing high surface densities of natural cytotoxicity receptors. SLAMF6 / Ly18 is a homodimer. It interacts with PTN6 and, upon phosphorylation, with PTN11 and SH2D1A/SAP. SLAMF6 / Ly18 undergoes tyrosine phosphorylation and associates with the Src homology 2 domain-containing protein (SH2D1A) as well as with SH2 domain-containing phosphatases (SHPs) . It may function as a coreceptor in the process of NK cell activation. SLAMF6 / Ly18 can also mediate inhibitory signals in NK cells from X-linked lymphoproliferative patients.

Overview

A DNA sequence encoding the human SLAMF6 (Q96DU3-1) extracellular domain (Met 1-Met 226) was expressed, with a polyhistidine tag at the C-terminus.

Field of Research

ITIM/ITAM Immunoreceptors and Related Molecules

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method.

Purity

> 90 % as determined by SDS-PAGE.

Activity

Measured by its ability to bind biotinylated recombinant human SH2D1A in a functional ELISA.

Form

Lyophilized

Buffer

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

Function

CD Molecule proteins

Molecular Weight

The recombinant human SLAMF6 consists of 216 amino acids and predictes a molecular mass of 24.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhSLAMF6 is approximately 38-40 kDa due to glycosylation.

Storage Conditions

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
