Recombinant Biotinylated Human Notch 1 Protein,His-Avi Tag

表达区间及表达系统（Source）

Biotinylated Human Notch 1 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Ala19-Gln526.[Uniprot :P46531]

分子量大小

（Molecular Weight）

The protein has a predicted MW of 56.5 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result.

内毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

纯度（Purity）

> 95% as determined by Tris-Bis PAGE and HPLC

活性（Activity）

SPR Data：Human DLL4, hFc Tag captured on CM5 Chip via Protein A can bind Biotinylated Human Notch 1, His Tag with an affinity constant of 0.31 μM as determined in SPR assay.

制剂（Formulation）

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.

重构方法（Reconstitution）

Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
