• Cat.No.: IL31-0224H
• Product Overview: Recombinant Human IL31 protein(Ser24-Thr164), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Human IL-31, His Tag at 1 μg/mL (100 μL/well) can bind Human IL-31 RA, Fc Tag with a linear range of 0.02-0.625 μg/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the N-terminusThe protein has a calculated MW of 17.7 kDa. The protein migrates as 23-33 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
