SPAM1, Recombinant, Human, aa36-490, His-SUMO-Tag (Hyaluronidase PH-20)

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 bedded 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. Source: Recombinant protein corresponding to aa36-490 from human SPAM1, fused to His-SUMO-Tag at N-terminal, expressed in E. coli.
