Recombinant Human KIR2DL1

Recombinant Human KIR2DL1 (C-6His) (C16K)

产品说明(Description)

Recombinant Human Killer Cell Immunoglobulin-like Receptor 2DL1 is produced by our Mammalian expression system and the target gene encoding His22-His245 is expressed with a 6His tag at the C-terminus.

Accession #: P43626

Known as: CD158 antigen-like family member A; CD158a antigen; CD158a;KIR2DL1; MHC class I NK cell receptor; Natural killer-associated transcript 1; NKAT; NKAT-1; p58.1 MHC class-I-specific NK receptor

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control)

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening.  Do not mix by vortex or pipetting. 

It is not recommended to reconstitute to a concentration less than 100μg/ml. 

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.  

Aliquots of reconstituted samples are stable at < -20°C for 3 months.

 

背景(Background)

Killer cell immunoglobulin-like receptor 2DL1 (KIR2DL1) is an inhibitory Natural Killer cell immunoglobulin-like receptor with two extracellular immunoglobulin domains. KIR2DL1 down-regulates the cytotoxicity of NK cells upon recognition of specific class I major histocompatibility complex (MHC) molecules on target cells. It has been reported that the KIR2DL1 is bound to its class I MHC ligand, HLA-Cw4. The KIR2DL1-HLA-Cw4 interface exhibits charge and shape complementarity.  KIR/HLA-I interactions can act through inhibition of NKC activation by target cells and NKC licensing for greater intrinsic responsiveness.
