Validation Data Gallery

• 

  FC experiment of Jurkat using CL555-11565

  1X10^6 Jurkat cells were intracellularly stained with 0.4 ug CoraLite® Plus 555 Anti-Human STIM1 (CL555-11565) (red), or 0.4 ug CoraLite®555-conjugated Rabbit IgG control Rabbit PolyAb (CL555-30000, Clone: ) (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C).

Tested Applications

• Positive FC detected in: Jurkat cells

Recommended dilution

• Flow Cytometry (FC): FC : 0.40 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Sample-dependent, Check data in validation data gallery.

Background Information

STIM1, also named as GOK, is an ER Ca2+ sensor. Upon Ca2+ store depletion, STIM1 clusters at ER-plasma membrane junctions where it interacts with and gates Ca2+-permeable Orai1 ion channels. STIM1 is implicated in tumor growth suppression and stromal-haematopoietic cell interactions. Defacts in STIM1 gene can cause immune dysfunction with impaired T-cell activation. STIM1 can inhibit L-type voltage-gated Ca(2+) channels in neurons. Temperature is an important regulator of STIM1 function.The MW of STIM1 is about 80-90 kDa which may be due to the phosphorylation or glycosylation forms. Catalog#11565-1-AP is rabbit polyclonal antibody raised against the N-terminal of human STIM1.
