Additional Information

Alternative name: Stromal interaction molecule 1 (STIM1, GOK)

UniProt: Q13586

Immunogen: A synthetic peptide from the extracellular domain of human Stromal interaction molecule 1 (STIM1) conjugated to an immunogenic carrier protein was used as the immunogen. The antigen is homologous in rat and mouse.

Format: Lyophilized

Isotype: IgG

Description: FUNCTION: Plays a role in mediating Ca2+ influx following depletion of intracellular Ca2+ stores. Acts as Ca2+ sensor in the endoplasmic reticulum via its EF-hand domain. Upon Ca2+ depletion, translocates from the endoplasmic reticulum to the plasma membrane where it activates the Ca2+ release-activated Ca2+ (CRAC) channel subunit, TMEM142A/ORAI1. SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. Endoplasmic reticulum membrane; Single-pass type I membrane protein. Note: Translocates from the endoplasmic reticulum to the cell membrane in response to a depletion of intracellular calcium. Tissue specificity: Ubiquitously expressed in various human primary cells and tumor cell lines. Also known as: STIM1, GOK.

Specificity: Appears to be specific for STIM1.

Application Details

Application Notes: IHC, WB. A concentration of 10-50 µg/ml is recommended. The optimal concentration should be determined by the end user. Not tested in other applications.

Purity: IgG

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
