• Cat.No.: IL1B-1602H
• Product Overview: Biotinylated Recombinant Human IL1B protein(Ala117-Ser269), fused with His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: 117-269 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Human IL-1 RII, Fc Tag at 5 μg/mL (100 μL/well) can bind Biotinylated Human IL-1 beta, His,Avitag with a linear range of 0.3-10 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™)The protein has a calculated MW of 21.0 kDa. The protein migrates as 26-28 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
