C₂₆H₂₃N₃O₁₀ 4K

光谱特性：

产品描述：QUIN 2, Tetrapotassium Salt has been demonstrated to be an indicator of Zn²⁺-protein complexes.The binding of Ca²⁺ to QUIN 2 leads to a major shift in UV absorption spectrum and a twenty-fold enhancement in fluorescence quantum yield. TPEN can be used in conjunction with QUIN 2 to reduce heavy-metal quenching of QUIN 2 fluorescence in cells. Spectral properties in the presence of low calcium concentrations (ex. 354 nm, em. 510 nm) differ from those during high calcium conditions (ex. 332 nm, em. 505 nm).

应用：A useful fluorescing calcium indicator

保存方法：Store at -20° C

溶解性：Soluble in water (10 mg/ml).
