Applications

Our Abpromise guarantee covers the use of ab59342 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 1 µg/ml. Detects a band of approximately 95 kDa (predicted molecular weight: 84 kDa).Can be blocked with STIM2 peptide (ab176417).
ICC/IF Use a concentration of 1 µg/ml.
ELISA Use at an assay dependent concentration.

Target

  • FunctionFunctions as a highly sensitive Ca(2+) sensor in the endoplasmic reticulum which activates both store-operated and store-independent Ca(2+)-influx. Regulates basal cytosolic and endoplasmic reticulum Ca(2+) concentrations. Upon mild variations of the endoplasmic reticulum Ca(2+) concentration, translocates from the endoplasmic reticulum to the plasma membrane where it probably activates the Ca(2+) release-activated Ca(2+) (CRAC) channels ORAI1, ORAI2 and ORAI3. May inhibit STIM1-mediated Ca(2+) influx.
  • Tissue specificityExpressed in all tissues and tumor cell lines examined.
  • Sequence similaritiesContains 1 EF-hand domain.
    Contains 1 SAM (sterile alpha motif) domain.
  • Post-translational
    modifications
    Glycosylated.
    Phosphorylated predominantly on Ser residues.
  • Cellular localizationEndoplasmic reticulum membrane. Dynamically translocates from a uniform endoplasmic reticulum distribution to punctual endoplasmic reticulum-plasma membrane junctions in response to decrease in endoplasmic reticulum Ca(2+) concentration.

  • ICC/IF image of ab59342 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab59342, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
