• Cat.No.: APOE4-2873H
• Product Overview: Recombinant Human APOE protein(R154S, R176C)(Lys 19-His 317),fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 19-317 aa (R154S, R176C)
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Loaded Biotinylated Human TREM2, His,Avitag on SA Biosensor, can bind Human APOE3, His Tag with an affinity constant of 37.1 nM as determined in BLI assay (ForteBio Octet Red96e).
• Molecular Mass: The protein has a calculated MW of 36.1 kDa. The protein migrates as 35-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
