Powered by BiozSpecifications
- HOST SPECIES: Rabbit
- SPECIES REACTIVITY: Human, Mouse, Rat
- HOMOLOGY: Predicted species reactivity based on immunogen sequence: Bovine: (100%)
- IMMUNOGEN: STIM1 antibody was raised against a 24 amino acid synthetic peptide from near the carboxy terminus of human STIM1.
The immunogen is located within the last 50 amino acids of STIM1. - CONJUGATE: Unconjugated
- TESTED APPLICATIONS: ELISA, IF, IHC-P, WB
- APPLICATION NOTE: STIM1 antibody can be used for detection of STIM1 by Western blot at 1 - 2 μg/mL. Antibody can also be used for immunohistochemistry starting at 2.5 μg/mL.
Antibody validated: Western Blot in mouse samples; Immunohistochemistry in human and mouse samples and Immunofluorescence in human and mouse samples. All other applications and species not yet tested. - SPECIFICITY: At least two isoforms of STIM1 are known to exist; this antibody will detect only the larger form. This STIM1 antibody is predicted to have no cross-reactivity to STIM2.

Background
- STIM1 Antibody: In T lymphocytes, the sole pathway for Ca2+ entry following antigen-receptor binding is through store-operated Ca2+-release-activated Ca2+ (CRAC) channels. These channels are made up of the pore-forming subunit ORAI1 and the stromal interaction molecule 1 (STIM1), a protein that functions as a Ca2+ sensor and activates the CRAC channels, migrating to the plasma membrane from endoplasmic reticulum (ER)-like sites which act as the Ca2+ store. A related molecule, STIM2, acts to inhibit the STIM1-mediated store-operated Ca2+ entry, and can form complexes with STIM1, suggesting they may play a coordinated role in controlling Ca2+ entry.
