Anti-STIM1 antibody produced in rabbit

Stromal interaction molecule 1 precursor recombinant protein epitope signature tag (PrEST)

Anti-STIM1 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.

Stromal Interaction Molecule 1 (STIM1) is a 90kDa cell surface transmembrane protein consisting of Ca²⁺ binding domains. It is localized in the endoplasmic reticulum (ER). In ER, depletion of stored Ca²⁺ ions activates the STIM1 and upon activation, it turns into multimeric form. These multimers translocate to the ER-plasma membrane junctions for the activation of Ca²⁺ channel. It mediates the store-operated calcium entry (SOCE) for normal cell functioning. It is also involved in the tumor growth suppression and stromal-haematopoietic cell interactions. Mutations in STIM1 cause autosomal-recessive hypomaturation enamel malformations.

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.

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
