Description
- General description: Binding of Ca2+ leads to a major shift in UV absorption spectrum and a twenty-fold enhancement in fluorescence quantum yield. TPEN (Cat. No. 616394) can be used in conjunction with QUIN 2 to reduce heavy-metal quenching of QUIN 2 fluorescence in cells.
- Biochem/physiol Actions: Cell permeable: no
- Warning: Toxicity: Irritant (B)
- Reconstitution: Following reconstitution, aliquot and freeze (-20°C) under an inert gas, pH >10. Stock solutions are stable for up to 6 months at -20°C.
