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