Envelope glycoprotein gp140/gp140 (HIV)
Biotinylated Human immunodeficiency virus 1 gp140 Protein, His,Avitag (GP0-V82E3) is expressed from human 293 cells (HEK293). It contains AA Ala 30 - Asp 661 (Accession # ABA61516.1).
Predicted N-terminus: Ala 30

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 53.8 kDa & 20.9 kDa. The protein migrates as 95-120 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Within the expressed region, several mutations were introduced to optimize the protein expression and stability.
The protein is designed as a trimer.
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Passed as determined by the SABA assay / HABA assay / binding ELISA.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 0.1 M Sodium citrate, pH5.5 with trehalose as protectant.
