Name : Biotinylated Human MICB Protein
Product Source :
Recombinant Biotinylated Human MICB Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ala23-Gly298.[Accession | Q29980]
Molecular Weight :
The protein has a predicted MW of 34.4 kDa. Due to glycosylation, the protein migrates to 48-65 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Biotinylated Human MICB on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human MICB is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Anti-MICB Antibody, hFc Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Human MICB, His Tag with the EC50 of 0.43μg/ml determined by ELISA (QC Test). SPR Data Human NKG2D, hFc Tag captured on CM5 Chip via Protein A can bind Biotinylated Human MICB, His Tag with an affinity constant of 60.38 nM as determined in SPR assay (Biacore T200).
Background :
MICB (MHC class I chain-related gene B) is a transmembrane glycoprotein that functions as a ligand for NKG2D. A closely related protein, MICA, shares 85% amino acid identity with MICB.MICB Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis.
Synonyms :
MICB; MIC-B; PERB11.2
