蛋白结构(Molecular Characterization)

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 57.1 kDa. The protein migrates as 65-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

NKG2C & CD94 SDS-PAGE

Human NKG2C&CD94, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

NKG2C & CD94 ELISA

Immobilized Human NKG2C&CD94, Fc Tag (Cat. No. NC4-H5258) at 5 μg/mL (100 μL/well) can bind PE-Labeled Human HLA-E*01:03&B2M&CMV UL40 (VMAPRTVLL) Tetramer Protein (Cat. No. HLU-HP2H5) with a linear range of 0.01-5 μg/mL (QC tested).

Protocol

 

背景(Background)

CD94 plays a role as a receptor for the recognition of MHC class I HLA-E molecules by NK cells and some cytotoxic T-cells. KLRD1 (CD94) is an antigen preferentially expressed on NK cells and is classified as a type II membrane protein because it has an external C terminus. NKG2C/CD159c is used as a receptor for NK cells and some cytotoxic T cells to recognize MHC class I HLA-E molecules. CD94 pairs with the NKG2 molecule as a heterodimer. The CD94/NKG2 complex, on the surface of natural killer cells interacts with Human Leukocyte Antigen (HLA)-E on target cells.
