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: Human LDL R, Fc Tag captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human APOE2, His Tag with an affinity constant of 16.2 nM as determined in a SPR assay (Biacore 8K).
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminusThe protein has a calculated MW of 36.1 kDa. The protein migrates as 35-43 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
