Caldesmon recombinant protein epitope signature tag (PrEST)

Application

Anti-CALD1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

Caldesmon 1 is a cytoskeleton-associated protein encoded by the gene CALD1. It is capable of binding to actin and functions in the stabilization of actin filaments. It can also bind to calmodulin and play a role in the regulation of smooth muscle and nonmuscle contraction. The binding domain of this protein also binds to tropomyosin, myosin, and phospholipids. CALD1 has been implicated in actin cytoskeletal modeling and cell migration. It is associated with actin stress fibers and membrane ruffles, where it plays a role in the polymerization of these fibers. It also functions in cell division, adhesion and apoptosis. It serves as a marker for distinguishing muscularis propria from desmoplasia, facilitating proper staging of colonic adenocarcinoma. It plays a role in gastric cancer metastasis.

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.

An accurate distinction between deep muscularis propria invasion versus subserosal invasion by colonic adenocarcinoma is essential for the accurate staging of cancer and subsequent optimal patient management. However, problems may arise in pathologic staging when extensive desmoplasia blurs the junction
