Biolegend, 317109, Purified anti-human CD158a/h (KIR2DL1/KIR2DS1) 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. CD158a and CD158h are 38-50 kD two extracellular Ig domain single-pass glycoprotein that contains a short cytoplasmic tail for KIR2DL1. It is expressed primarily on a subset of NK cells and a subset of T cells. KIR2DL1 and KIR2DS1 have been reported to bind certain HLA-C antigens on target cells (HLA-C*02, HLA-C*04, HLAC*06, for example).
100μg
Verified Reactivity: Human
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: Human KIR2DS1 transfected cells
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 S22013A can block the binding of clone HP-DM1 on target cells and is not blocked by HP-DM1. Based on in-house testing on different KIR-expressing transfectants, clone S22013A does not interact with other KIR protein family members.
