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 regions, lack ITIM and have activation functions. Fourteen polymorphic KIR genes have been reported in humans. KIR2DL4 (CD158d) is a unique receptor which has an ITIM in its cytoplasmic domain and a charged residue in the transmembrane domain. It possesses both inhibitory and activation functions. Two common alleles (10A and 9A) of KIR2DL4 have been reported. The 10A allele (with 10 adenines at the end of the transmembrane exon) receptor is expressed on CD56high NK subset, whereas its expression on CD56dim NK cells is inducible upon culture. The major 9A allele receptor is a secreted form. HLA-G is the ligand of CD158d.

- 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 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.
- Excitation Laser

Red Laser (633 nm)
- Application Notes
-
KIR2DL4 expression in NK cells is highly localized to the endosomes3. mAb 33 can be internalized by NK cells by endocytosis at 37°C3, and induces NK cell cytotoxicity1,2. Based on in-house observations, we suggest incubating for 45 - 60 minutes at room temperature with clone mAb 33 to observe better CD158d staining.
This clone has been tested in-house and determined to not be suitable for applications in immunohistochemistry of paraffin-embedded tissue sections (IHC-P). -
