Application Notes: This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 83.5 kDa. The protein migrates as 105-115 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation
Human IL-31, His Tag capture on NTA-Series S sensor chip can bind Human IL-31 RA, Fc Tag (Cat. No. orb570280) with an affinity constant of 37.1 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).
