Specification

• Source: HEK293
• Species: Human
• Tag: His-Avi
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tagThe protein has a calculated MW of 37.7 kDa. The protein migrates as 39-44 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
