Scientific Data Images for Bovine SPAM1 Antibody

Detection of Bovine SPAM1 antibody by Western Blot.

Detection of Bovine SPAM1 by Western Blot.

Western blot shows Recombinant Bovine SPAM1 (Catalog # 6436-GH) (5 ng/lane). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Bovine SPAM1 Monoclonal Antibody (Catalog # MAB6436) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for SPAM1 at approximately 78 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: SPAM1

Sperm adhesion molecule 1 (SPAM1), also known as PH-20 hyaluronidase (1), is encoded by one of the six hyaluronidase-like genes (1-3). SPAM1 is a GPI‑anchored enzyme located on the sperm surface and inner acrosomal membrane (4). SPAM1 degrades hyaluronic acid (HA), a major structural glycosaminoglycan found in extracellular matrices and basement membranes. The enzyme activity enables sperm to penetrate through the HA-rich cumulus cell layer surrounding the oocyte and therefore facilitates the fertilization process (5-7). Because of the structural similarity between HA (repeating units of GlcA beta 1-3GlcNAc) and chondroitin sulfate (repeating units of GlcA beta 1-3GalNAc), the enzyme is also able to hydrolyze chondroitin sulfate. The bovine SPAM1 is 63% identical to human homologue in sequence.
