PIGR Protein (C-His, Human)

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.

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.
