Scientific Data Images for Human STIM1 Antibody

STIM1 antibody in Human Brain by Immunohistochemistry (IHC-P).

STIM1 in Human Brain.

STIM1 was detected in immersion fixed paraffin-embedded sections of human brain (cerebellum) using Mouse Anti-Human STIM1 Monoclonal Antibody (Catalog # MAB69761) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in Purkinje neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: STIM1

STIM-1 (stromal interaction molecule 1), previously called GOK, is a 90 kDa type I transmembrane protein of the endoplasmic reticulum (ER). When STIM-1 senses depletion of calcium in the ER via its EF-hand domain (aa 63-98), it interacts with the plasma membrane Ca2+ release-activated Ca2+ (CRAC) channel Orai1, increasing Ca2+ influx. The human STIM-1 extracellular/lumenal domain (aa 23-213) contains an EF hand Ca2+-binding motif and a SAM (sterile a-motif) multimerization domain. A potential isoform is truncated at aa 491. Defects in STIM1 are the cause of immune dysfunction with T-cell inactivation due to calcium entry defect type 2 (IDTICED2). Within the region used as an immunogen, human STIM1 shares 95% amino acid identity with mouse and rat STIM1.
