Recombinant humaan NKG2D/KLRK1-eiwit

KLRK1, also known as NKG2D ligand 4 isoform 1, is a type ll 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. It can send co-stimulatory signals to activate CD8 T cells. Also, it plays an important role in viral control. Cellular stress can induce ligands for KLRK1 which results in the cell susceptible to NK cell-mediated lysis. Recombinant human KLRK1, fused to hIgG-His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.

Human ULBP-6/RAET1L (CAT# ATGP4023) is coated at 10 µg/mL (100 ul/well) can bind Human NKG2D. The ED50 range ≤ 1.5 µg/mL.
