Biolegend, 317614, Purified anti-human CD158b1/j (KIR2DL2/KIR2DS2) Antibody, 100μg

CD158 molecules, also known as KIRs (killer cell immunoglobulin-like receptors), are a family of transmembrane proteins with either two (KIR2D) or three (KIR3D) Ig-like extracellular domains. Some KIRs with long cytoplasmic domains contain ITIMs and possess inhibitory functions and others with short cytoplasmic region lack ITIM and have activation functions. Fifteen polymorphic KIR genes have been reported in humans. CD158b1 and CD158j, also known as KIR2DL2 and KIR2DS2, respectively, are glycoproteins with two extracellular Ig domains. KIR2DL2 displays a long cytoplasmic tail with ITIM motifs and is 38 kD. KIR2DS2, with a short cytoplasmic tail containing an ITAM motif, is 33 kD in size.  Both KIR2DL2 and KIR2DS2 are expressed primarily on a subset of NK cells and a subset of T cells. KIR2DL2 and KIR2DS2 have been reported to bind to certain HLA-C antigens on a target cell (HLA-C*01, HLA-C*03, HLA-C*07, for example).

Immunogen: Recombinant human KIR2DL2 protein
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/mL
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application: FC - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes: Clone S22032A does not block the binding of clone DX27 on target cells and is not blocked by DX27. Based on in-house testing on different KIR-expressing transfectants, clone S22032A does not interact with other KIR protein family members.
