蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus
The protein has a calculated MW of 32.1 kDa. The protein migrates as 36-46 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Cynomolgus DLK1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.
活性（Bioactivity）-ELISA
Immobilized Cynomolgus DLK1, His Tag (Cat. No. DK1-C52H7) at 1 μg/mL (100 μL/well) can bind anti DLK-1 antibody with a linear range of 0.078-5 μg/mL (QC tested).
Protocol
背景（Background）
Protein delta homolog 1 is a protein that in humans is encoded by the DLK1 gene. It is expressed as a transmembrane protein, but a soluble form cleaved off by ADAM17 is active in inhibiting adipogenesis, the differentiation of pre-adipocytes into adipocytes.
