Active Recombinant Human PIGR protein(Met1-Arg638, 365Ser/Gly), His-tagged

• Cat.No.: PIGR-829H
• Product Overview: Active Recombinant Human PIGR protein(Met 1-Arg 638, 365 Ser/Gly)(NP_002635.2) was expressed in Human Cells with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: Human Cells
• Tag: His
• Protein Length: 1-638 aa, 365 Ser/Gly
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its binding ability in a functional ELISA. 1. Immobilized rhhuman IgM at 2 μg/ml (100 μl/well) can bind biotinylated PIGR with a linear range of 0.94-15 ng/ml. 2. When human human IgM is immobilized at 2 μg/ml (100 μl/well), PIGR inhibits 50% binding of biotinylated PIGR (0.062 μg/ml) at the concentration range of 0.03-20 μg/ml.
• Molecular Mass: The soluble form of recombinant human PIGR consists of 630 amino acids after removal of the signal peptide and has a predicted molecular mass of 69 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 80-90 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
