Form

Lyophilized from sterile 100mM Glycine, 10mM NaCl, 50mM Tris, pH 7.5, 5 % trehalose and 5 % mannitol.

Bio-activity

Measured by its binding ability in a functional ELISA. Immobilized recombinant human Angiopoietin-2 at 10 μg/ml (100 μl/well) can bind Human Tie2 / Fc chimera with a range of 0.2-20 μg/ml.

Molecular Mass

Recombinant Human Tie2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 970 amino acids and predicts a molecular mass of 108.5 kDa. As a result of glycosylation, the apparent molecular mass of rhTie2/Fc monomer is approximately 125-135 kDa in SDS-PAGE under reducing conditions.

Endotoxin

< 1.0 EU per 1 microgram of protein (determined by LAL method).

Purity

> 90 % by SDS-PAGE.

BACKGROUND

Background

Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.
