表达序列（Sequence）

Met113-Leu261

Accession

P29965

标签（Tag)

N-His-Avi,N-Flag

分子量（Molecular Weight）

The protein has a predicted MW of 54.51 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result.

内毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

纯度（Purity）

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

活性（Activity）

ELISA Data: Immobilized Biotinylated Human CD40 Ligand Trimer, His Tag at 2μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human CD40, hFc Tag with the EC50 of 56.2ng/ml determined by ELISA.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
