Product Specification

Alternative Name:COMP:Ang-1
Source:Produced in CHO cells. The fibrinogen-like domain (aa 284-498) of human Ang-1 (angiopoietin-1) is fused at the N-terminus to the coiled-coil domain of rat COMP (cartilage oligomeric matrix protein) and to a FLAG®-tag.
UniProt ID:Q15389 (human Angiopoietin-1), P35444 (rat COMP)
Formulation:Liquid. 0.2µm-filtered solution in PBS containing 0.01% CHAPS.
Purity:≥90% (SDS-PAGE)
Endotoxin Content:<0.1EU/µg protein (LAL test; BioWhittaker)
Specificity:Binds to human Tie-2.
Biological Activity:Induces phosphorylation of Tie-2 in primary cultured human and mouse vascular endothelial cells. More potent than native Ang-1.
Shipping:Shipped on Dry Ice
Long Term Storage:-80°C
Use/Stability:Working aliquots are stable for up to 3 months when stored at -80°C.
Handling:Avoid freeze/thaw cycles. After opening, prepare aliquots and store at -80°C.
Technical Info/Product Notes:FLAG is a registered trademark of Sigma-Aldrich Co.

Figure 1: COMP (rat):Angiopoietin-1 (human) (rec.) (Prod. No. ALX-201-314) forms mainly pentameric structures. Method: Glycerol spraying/low angle rotary metal-shadowed specimens were imaged by transmission electron microscopy.

Figure 2: COMP (rat):Angiopoietin-1 (human) (rec.) (Prod. No. ALX-201-314) induces phosphorylation of Tie-2 in human umbilical vein endothelial cells.Method: Serum-starved human umbilical vein endothelial cells were treated with 200ng/ml of BSA (Co) or 20ng/ml of COMP:Angiopoietin-1 for 15 min. The phosporylation of Tie-2 (phospho-Tie-2) was measured after immunoprecipitation.
