Human KIR2DS1/CD158h PE-conjugated Antibody Summary

Species Reactivity
Detects human KIR2DS1/CD158h in flow cytometry. Clone 1127B recognizes KIR2DS1 and some alleles of KIR2DL1, both members of the killer cell immunoglobulin-like receptor (KIR) family. Because Clone 1127B displays partial cross-reactivity with KIR2DL1, co-staining with Mouse Anti-Human KIR2DL1 Clone 143211 (Catalog # FAB1844A) is recommended.
Recombinant Monoclonal Rabbit IgG Clone # 1127B
Protein A or G purified from cell culture supernatant
HEK293 human embryonic kidney cell line transfected with human KIR2DS1/CD158h
Accession # Q14954
Supplied in a saline solution containing BSA and Sodium Azide.


Recommended Concentration
Flow Cytometry
10 µL/106 cells
See below

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: KIR2DS1/CD158h

The KIRs comprise a family of 14 polymorphic and homologous activating and inhibitory receptors expressed primarily on CD56dim NK cells. KIR2DS1 is an activating receptor with high homology to the inhibitory receptor KIR2DL1. Both KIR2DL1 and KIR2DS1 bind to HLA-C alleles containing the C2 epitope. KIR2DS1 and KIR2DL1 expression regulates NK cell licensing and activation in a number of immune contexts. Over amino acids (aa) 1-245, human KIR2DS1 shares 97% aa sequence identity with human KIR2DL1.
