表达区间及表达系统（Source）

MABSol® Biotinylated Human EphB4, His Tag, primary amine labeling (EP4-H8229) is expressed from human HEK293 cells. It contains AA Leu 16 - Ala 539 (Accession # NP_004435.3). It is the biotinylated form of Human EphB4, His Tag (EP4-H5229).

Predicted N-terminus: Leu 16

蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 57.9 kDa. The protein migrates as 60-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

偶联（Conjugate）

Biotin

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.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

97% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
