STIM1 Antibody is affinity chromatography purified via peptide column.
1 mg/mL (lot specific)
STIM1 antibody was raised against a 24 amino acid synthetic peptide from near the carboxy terminus of human STIM1.
STIM1 Antibody is supplied in PBS containing 0.02% sodium azide.
Preparation and Storage
STIM1 antibody can be stored at 4 degree C for three months and -20 degree C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
Other Notes
Small volumes of anti-STIM1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-STIM1 antibody
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.

NCBI Summary for STIM1
This gene encodes a type 1 transmembrane protein that mediates Ca2+ influx after depletion of intracellular Ca2+ stores by gating of store-operated Ca2+ influx channels (SOCs). It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocrotical carcinoma, and lung, ovarian, and breast cancer. This gene may play a role in malignancies and disease that involve this region, as well as early hematopoiesis, by mediating attachment to stromal cells. Mutations in this gene are associated with fatal classic Kaposi sarcoma, immunodeficiency due to defects in store-operated calcium entry (SOCE) in fibroblasts, ectodermal dysplasia and tubular aggregate myopathy. This gene is oriented in a head-to-tail configuration with the ribonucleotide reductase 1 gene (RRM1), with the 3' end of this gene situated 1.6 kb from the 5' end of the RRM1 gene. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]
UniProt Comments for STIM1
STIM1: Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Acts as Ca(2+) sensor in the endoplasmic reticulum via its EF-hand domain. Upon Ca(2+) depletion, translocates from the endoplasmic reticulum to the plasma membrane where it activates the Ca(2+) release-activated Ca(2+) (CRAC) channel subunit, TMEM142A/ORAI1. Forms homooligomers and heterooligomers with STIM2. Interacts with ORAI1. Interacts with MAPRE1; probably required for targeting to the growing microtubule plus ends. Interacts with EFCAB4B/CRACR2A; the interaction is direct and takes place in absence of Ca(2+). Forms a complex with EFCAB4B/CRACR2A and ORAI1 at low concentration of Ca(2+), the complex dissociates at elevated Ca(2+) concentrations. Interacts with TMEM66/SARAF, promoting a slow inactivation of STIM1-dependent SOCE activity, possibly by facilitating the deoligomerization of STIM1. Ubiquitously expressed in various human primary cells and tumor cell lines.
