Angiopoietin-2 Protein, Mouse (CHO, His)

Angiopoietin 2 protein (ANGPT2) binds to TEK/TIE2, competes with ANGPT1, and modulates its signaling. Even in the absence of ANGPT1, ANGPT2 induces TEK/TIE2 phosphorylation. Angiopoietin-2 Protein, Mouse (CHO, His) is the recombinant mouse-derived Angiopoietin-2 protein, expressed by CHO, with C-His labeled tag.

Angiopoietin-2 Protein (ANGPT2) binds to TEK/TIE2 and competes with ANGPT1 for the binding site, thereby modulating ANGPT1 signaling. It has the ability to induce tyrosine phosphorylation of TEK/TIE2 even in the absence of ANGPT1. In the absence of angiogenic inducers like VEGF, ANGPT2 can cause loosening of cell-matrix contacts, potentially leading to endothelial cell apoptosis and subsequent vascular regression. However, when working in conjunction with VEGF, it can promote endothelial cell migration and proliferation, making it a permissive angiogenic signal. ANGPT2 also plays a role in the regulation of lymphangiogenesis. Additionally, it interacts with TEK/TIE2, competing for the same binding site as ANGPT1, and interacts with ITGA5.

Full Length of Mature Protein

Approximately 60-70 kDa,based on SDS-PAGE under reducing conditions,due to the glycosylation.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from 0.22 μm filtered solution of 20 mM MOPS, 150 mM NaCl, 5 mM CHAPS, pH7.5 with trehalose as protectant.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
