Protocol Available protocols: Flow Cytometry (Fixed/Permeabilized) Specificity / Sensitivity Survivin (71G4B7) Rabbit Monoclonal Antibody (Alexa Fluor Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding cysteine 60 of human survivin. The antibody was conjugated to Alexa Fluor 647 under optimal conditions with an F/P ratio of 2-6. The Alexa Fluor 647 dye is maximally excited by red light (e.g. 633 nm He-Ne laser). Antibody conjugates of the Alexa Fluor 647 dye produce bright far-red-fluorescence emission, with a peak at 665 nm. Background Survivin is a 16 kDa anti-apoptotic protein highly expressed during fetal development and cancer cell malignancy (1). Survivin binds and inhibits caspase-3, controlling the checkpoint in the G2/M-phase of the cell cycle by inhibiting apoptosis and promoting cell division (2,3). This regulatory process requires the phosphorylation of survivin at Thr34 by p34 cdc2 kinase (4). Gene targeting using a Thr34 phosphorylation-defective survivin mutant, as well as antisense survivin, have been shown to inhibit tumor growth (5,6).
