Description générale

The signaling interactions of ANG-1, ANG-2 and Tie2, along with less characterized ANG-3 and ANG-4, are required for embryonic and adult angiogenesis.  Physiologically, ANG-1 and ANG-2 are associated with sprouting, tube formation, and structural integrity of newly formed blood vessels.  Mature human ANG-2 is a secreted protein containing 480 amino acid residues.  ANG-2 is composed of an alpha helix rich “coiled coil” N-terminal domain and fibrinogen like C-terminal domain.

Actions biochimiques/physiologiques

ANG-2 binds to the endothelial cell specific receptor Tie2, but, in contrast to ANG-1 does not induce tyrosine phosphorylation.  Consequently, ANG-2 modulates ANG-1 activation of Tie2 and, depending on the physiological and biochemical environment, can act either as a n agonist or antagonist of Tie2 induced angiogenesis.  ANG-2 exists predominantly in the form of a disulfide-linked dimer. Recombinant human ANG-2 is a C-terminal histidine tagged glycoprotein which migrates with an apparent molecular mass of 60.0 – 70.0 kDa by SDS-PAGE under reducing conditions. Sequencing analysis shows an N-terminal sequence starting with residue 68 (D) of the ANG-2 precursor protein.

Forme physique

Lyophilized from 10 mM Sodium Phosphate, pH 8.0.


Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Angiopoietin-2 (Ang2) is a naturally occurring antagonist of angiopoietin-1 (Ang1) that competes for binding to the Tie2 receptor and blocks Ang1-induced Tie2 autophosphorylation during vasculogenesis. Using the polymerase chain reaction, we isolated a cDNA encoding a novel shorter form of...
