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

CLOCK (circadian locomotor output cycles kaput), circadian protein, is present in the Z-disk of the myofilaments and is controlled by cross-bridge cycling. It is involved with glucose and fatty acid metabolism. CLOCK protein binds to BMAL1 (brain and muscle ARNT-like 1) to form heterodimer complex. This binding activity enhances the transcription of target genes such as PER (period circadian clock) and CRY (cryptochrome) genes. Furthermore, PER-CRY complex relocates into the nucleus to suppress the CLOCK/BMAL1 complex activity. Thus, it regulates gene expression in a cyclic manner.

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.

In the mammalian heart, the circadian protein Clock regulates glucose and fatty acid metabolism. In this study, we determined some of the factors that regulate Clock expression and subcellular distribution in myocytes. Using immunochemistry and biochemical subcellular fractionation, we have

The protein deacetylase, sirtuin 1 (SIRT1), involved in regulating hepatic insulin sensitivity, shows circadian oscillation and regulates the circadian clock. Recent studies show that circadian misalignment leads to insulin resistance (IR); however, the underlying mechanisms are largely unknown. Here, we
