Recombinant protein orresponding to Ile27-Ser159 from human CD160 expressed in CHO cells.
CD160 is a 27kD member of Ig superfamily of molecules. It is expressed on select hematopoietic cell types, including CD56dimCD16+ cytotoxic NK cells, CD8+CD28 effector T cells,Yd T cells, and restricted CD4+ T cells. It is a receptor for HLAC molecules, and its engagement induces CD160+NK cells to both secrete IFN-g plus TNF-a, and initiate a cytotoxic program. Human CD160 was originally identified as a 155aa pro-protein aa27-181 (SwissProt O95971). It contains a 132aa mature region aa27-159 and a C-terminal pro-segment that is cleaved to create a GPI linkage. The mature region possesses one V-type Ig-like domain aa27-122. CD160 is found as a soluble, disulfide-linked 80kD multimer (likely trimer) that is generated by proteolysis of the GPI-linked form. This 80kD form, plus others, are highly resistant to reduction. There is also a 100-110kD multimeric transmembrane (TM) form that is associated with activated NK cells. It contains a 55aa substitution for aa180-181, and shows a 20aa TM segment between aa163-182. The TM form appears to have a splice variant that lacks aa25-133. Over aa27-159, human CD160 shares only 62% aa sequence identity with mouse CD160. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Excitation: 620-650nm Emission: 660-670nm Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: APC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
