IGFBP4, IBP-4
Biotinylated Human IGFBP-4 Protein, His,Avitag (IG4-H82E3) is expressed from human 293 cells (HEK293). It contains AA Asp 22 - Glu 258 (Accession # P22692-1).
Predicted N-terminus: Asp 22
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 29.6 kDa. The protein migrates as 35-40 kDa and 41-42 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
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.
>95% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
