Anti-CA4 antibody produced in rabbit

半岛bd体育手机客户端 说明

一般描述

CA4 (carbonic anhydrase IV) is a 35kDa glycosylphosphatidylinositol-anchored membrane protein belonging to the zinc metalloprotein family. It is synthesized as a precursor of 312 amino acids, in endoplasmic reticulum and resides in the plasma membrane of endothelial and epithelial cells of multiple organs. It is localized to human chromosome 17q23, spans 9.5kb, and has seven introns and eight exons.

应用

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.

生化/生理作用

CA4 (carbonic anhydrase IV) regulates transport of CO₂and HCO₃^-1, in other term maintains homeostasis of CO2 and HCO₃^-as well as the tissue pH. It is anchored to the plasma membrane through glycosyl-phosphatiydyl-inositol (GPI) moiety. CA4 is expressed in the choriocapillaries of eye and epithelium of kidney. In eye, it provides oxygen to retinal pigment epithelium (RPM), by catalyzing the reversible conversion of CO₂to HCO₃^-. This in turn nourishes the photoreceptor cells. Retinitis pigmentosa type 17 is caused by mutation leading to arginine being replaced by tryptophan (R14W) in the signal peptide of CA4.

特点和优势

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.
