详细介绍

 

Endoglin (CD105) is a 90 kDa type I transmembrane glycoprotein of the zona pellucida (ZP) family of proteins. Endoglin is highly expressed on proliferating vascular endothelial cells, chondrocytes, and syncytiotrophoblasts of term placenta, with lower amounts on hematopoietic, mesenchymal and neural crest stem cells, activated monocytes, and lymphoid and myeloid leukemic cells. Endoglin homodimers interact with TGF‑ beta 1 and TGF‑ beta 3 (but not TGF‑ beta 2), but only after binding T beta RII. Similarly, they interact with activin‑A and BMP‑7 via activin type IIA or B receptors, and with BMP‑2 via BMPR‑1A/ALK‑3 or BMPR‑1B/ALK‑6. BMP‑9, however, is reported to bind endoglin directly. Endoglin modifies ligand‑induced signaling in multiple ways. For example, expression of endoglin can inhibit TGF‑ beta 1 signals but enhance BMP7 signals in the same myoblast cell line. In endothelial cells, endoglin inhibits T beta RI/ALK5, but enhances ALK1‑mediated activation.

表达区间及表达系统

Recombinant Human Endoglin/CD105 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Glu26-Gly586.

分子量

Approximately 63.7 kDa. Due to glycosylation, the protein migrates to 70-82 kDa based on Tris-Bis PAGE result.

纯度

> 95% as determined by SDS-PAGE and HPLC.

活性

ELISA DataImmobilized Human Endoglin, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Anti-Endoglin Antibody, hFc Tag with the EC50 of 13.4ng/ml determined by ELISA.

内毒素

1.0 EU per 1μg of the protein by the LAL method.

制剂

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

复溶

Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.


运输与保存方法

冰袋运输-20-80存,一年有效期

复溶后,-20 -80°C,在未开封状态下保存 3-6 个月复溶后,2-8°C 保存 2-7 天。
