| Form | Lyophilized To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in 20 mM Tris, 150 mM NaCl, pH 8.0. If a higher concentration is required, the product can be reconstituted directly in 20 mM Tris, 150 mM NaCl, pH 8.0, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex. |

Descripción
Killer cell immunoglobulin-like receptors (KIRs) are a family of proteins primarily expressed on the surface of natural killer (NK) cells and some T-cell subsets, where they play a crucial role in the innate immune system. KIR2DL1, a member of this family, specifically recognizes certain human leukocyte antigen (HLA) class I molecules, allowing NK cells to monitor cellular health by detecting variations in HLA expression. KIR2DL1 is an inhibitory receptor, meaning that its engagement generally suppresses NK cell cytotoxic activity. The interaction between KIR2DL1 and HLA class I molecules is part of a broader system known as immune surveillance, where NK cells detect and respond to stress or infection signals on potential target cells, such as virally infected or transformed cells. KIRs are highly polymorphic and exhibit considerable variability among individuals. This diversity contributes to the versatility of NK cell responses, enhancing the immune system's adaptability. The genes encoding KIR proteins, including KIR2DL1, are located on chromosome 19q13.4 in the leukocyte receptor complex (LRC). KIR2DL1 recognizes HLA-C molecules, specifically those with the C2 epitope (HLA-C group 2), which consists of specific amino acid sequences.

Killer Cell Immunoglobulin Like Receptor 2DL1 (KIR2DL1) Antibody
KIR2DL1 Antibody is a Rabbit Polyclonal antibody against KIR2DL1. Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.
