Anti-SPACA1 antibody produced in rabbit

HPA026744    Human Protein Atlas characterization data

Sperm acrosome associated 1(spaca1) belongs to the family of globozoospermia-related genes. This protein is present in the equatorial segment of mammalian spermatozoa. The gene coding for spaca1 protein is mapped to human chromosome 6q15. Its expression is found to be in sync with acrosome development in human testicular cells.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Sperm acrosome associated 1(spaca1) plays a vital role in sperm-egg fusion. Proteomic analysis states that spaca1 concentration is decreased in globozoospermia patients. The encoded protein can be regulated by phosphorylation of conserved sequence atY268 tyrosine phosphorylation site.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
