表达区间及表达系统（Source）
Biotinylated Human VEGF165, epitope tag free, primary amine labeling (VE5-H8210) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Arg 191 (Accession # P15692-4). It is the biotinylated form of Human VEGF165, premium grade (Cat. No. VE5-H4210).
Predicted N-terminus: Ala 27
Request for sequence蛋白结构（Molecular Characterization）
This protein carries no "tag".
The protein has a calculated MW of 19.2 kDa. The protein migrates as 25-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a dimer.
标记（Labeling）
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.
蛋白标记度（Protein Ratio）
Passed as determined by the HABA assay / binding ELISA.
纯度（Purity）
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂（Formulation）
