Anti-HTRA3 antibody produced in rabbit

The gene HTRA3 (high-temperature requirement factor A3) is mapped to human chromosome 4p16.1. It belongs to the HTRA protein family. HTRA3 is strongly expressed in the heart and placenta. The protein contains an insulin/insulin-like growth factor binding domain, a Kazal-type S protease-inhibitor domain, a trypsin protease domain and a PDZ (PSD95, Dlg1, zo-1) domain.

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.

HTRA3 (high-temperature requirement factor A3) is an active serine protease. During placental development, it suppresses trophoblast invasion. It also controls ovarian development, differentiation of granulosa cell and luteinisation. Abnormal expression of HTRA3 is linked with preeclampsia. It is down-regulated in high grade endometrial cancer.

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.
