Angiopoeitin-1 (Ang-1) and Antiopoietin-2 (Ang2) are important for development of the endothelium, by regulating tyrosine phosphorylation of the membrane receptor Tie-2/Tek.
Ang-1 binding to Tie-2/Tek causes phosphorylation of the receptor.
Ang-2 competes for this binding, and thus blocks receptor phosphorylation.
Ang-1 has potential fibrinogen-like domain at the carboxy terminus and coiled-coil regions in the amino terminus.
Ang-1 is prominently expressed in the myocardium of atrium and ventricle, mesenchymal and smooth muscle cells surrounding most blood vessels, and lung.
In the adult, Ang-1 is also expressed in the heart and liver.
Ang 1 and Ang 2 antibodies recognize a band above 55 kD.
Both antibodies show banding at 75 kD which resembles the original size, because these are soluble highly glycosylated proteins, which should run higher that the calculated molecular weight of 55 kD.
Applications:Suitable for use in Western Blot and ELISA.
Other applications not tested.
Recommended Dilution:Western Blot: 1:250-1:500ELISA: 1:2500-1:10,000Optimal dilutions to be determined by the researcher.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage, store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
