Anti-ZP2 antibody produced in rabbit

ZP2 (zona pellucida glycoprotein 2) is a part of a translucent matrix called zona pellucida (ZP), which forms the outer layer of oocyte. It forms heterodimers with ZP3, which are cross-linked by ZP1. It has a molecular weight of 120kDa, and is composed of 713 amino acids. This gene is localized to human chromosome 16. ZP2 is synthesized as a precursor with a signal peptide at its N-terminal. It has a furin cleavage sequence at its C-terminal propeptide. This is followed by a transmembrane region and a short cytosolic tail.

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.

ZP2 (zona pellucida glycoprotein 2) interacts with ZP3, and this interaction is essential for the initiation of zona matrix formation. This protein is responsible for modulating secondary sperm binding to zona pellucida (ZP). Upon fertilization, ZP2 undergoes partial proteolysis, to produce a form called ZP2_f. This processed form might then prevent further penetration of ZP by other sperms.

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.
