General description

SPAG5 (Sperm associated antigen 5) is a mitotic microtubule-associated protein highly expressed in testis of pachytene spermatocytes.

Immunogen

Sperm-associated antigen 5 recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

SPAG5 (Sperm associated antigen 5) plays a vital role in the mitosis and cell cycle regulation by controlling the formation and organization of microtubule, checkpoint regulation during cell division. It acts as a regulator and binds to the spindle during separation of sister chromatids. It has also been reported that similar to other cell cycle-related proteins, it is also involved in DNA damage repair. It has been suggested that overexpression of SPAG5 may indicate a pathogenic role in testicular development of patients with Down′s syndrome and cryptorchidism.

Features and Benefits

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.
