ULBP-1 Protein, Human, Recombinant (His & Avi)

Catalog No. TMPK-00134

Cell surface proteins major histocompatibility complex (MHC) class I-related chain A (MICA) and UL16-binding proteins (ULBP) 1, 2, and 3 are up-regulated upon infection or tumor transformation and can activate human natural killer (NK) cells. ULBP-1 Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 25.2 kDa and the accession number is Q9BZM6.

Product Information

Biological Activity	Immobilized Human ULBP-1, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human NKG2D, hFc Tag with the EC50 of 33.2ng/ml determined by ELISA.
Description	Cell surface proteins major histocompatibility complex (MHC) class I-related chain A (MICA) and UL16-binding proteins (ULBP) 1, 2, and 3 are up-regulated upon infection or tumor transformation and can activate human natural killer (NK) cells. ULBP-1 Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 25.2 kDa and the accession number is Q9BZM6.
Species	Human
Expression System	HEK293 Cells
Tag	C-His-Avi
Accession Number	Q9BZM6
Synonyms	ULBP-1,ULBP1,NKG2DL1,NKG2DL,NKG2D ligand 1,N2DL-1,MULT-1,ALCAN-β,ALCAN-beta,AET1I
Construction	Gly26-Pro215
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	25.2 kDa (predicted). Due to glycosylation, the protein migrates to 28-35 kDa based on Tris-Bis PAGE result.
Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM PB, 0.5M NaCl, 0.1M L-arginine (pH 8.0). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	Cell surface proteins major histocompatibility complex (MHC) class I-related chain A (MICA) and UL16-binding proteins (ULBP) 1, 2, and 3 are up-regulated upon infection or tumor transformation and can activate human natural killer (NK) cells.
