Human NKG2D/CD314 Protein

Product Info

Recombinant Human NKG2D/CD314 Protein is expressed from Expi293 with His tag and Avi tag at the N-terminal. It contains Phe78-Val216 .[Accession | P26718]

Molecular Weight

The protein has a predicted MW of 19.0 kDa. Due to glycosylation, the protein migrates to 36-38 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE


Lyophilized from 0.22μm filtered solution in 20mM PB,150mM NaCl (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


The product should be stored at -70℃ or -20℃.

Assay Data
Tris-Bis PAGE

Human NKG2D on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


Immobilized Human NKG2D at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-NKG2D Antibody, hFc Tag with the EC50 of 4.7ng/ml determined by ELISA.


NKG2D is a type II transmembrane glycoprotein having an extracellular lectin-like domain. This domain lacks the recognizable calcium-binding sites found in true C-type lectins and binds protein rather than carbohydrate ligands. Human NKG2D is expressed on CD8 alpha beta T cells, gamma δ T cells, NK cells and NKT cells.
