Product introduction
注意事项: 1、试剂容易吸潮,从冰箱取出后,请确认在干燥的环境放至室温后再开封。由于试剂极其微量,开封前,请轻弹管壁几次,以保证粉末落入管底。 2、第一次使用时, 建议母液即配即用。试剂溶解后尽可能在短时间内使用,以保证实验效果。 3、溶解液 DMSO 需要保证新鲜无水,否则将会导致 AM 体水解,使荧光染料无法进入细胞,影响实验效果。 4、母液遇水极易分解,如果不能一次用完建议分装保存,例如分装成 5 μl/管,用封口膜封口,并用铝箔纸包裹,放在一个密闭性能好的塑料袋中,并放入一包干燥剂,在≤-20℃密封避光保存。 5、建议您在正式实验前先摸索一下细胞量、钙离子荧光探针的终浓度、培养时间等,找到最佳实验条件。 产品介绍: QUIN 2,四钾盐已被证实能够作为钙离子(Ca²⁺)与蛋白质复合物的指示剂。当钙离子(Ca²⁺)与QUIN 2结合时,它会导致紫外线吸收光谱发生显著变化,并使荧光量子产率提高二十倍。TPEN可以与QUIN 2配合使用,以降低细胞中QUIN 2荧光的重金属猝灭效应。在低钙浓度环境下(例如,激发波长为354nm,发射波长为510nm),其光谱特性与高钙浓度环境下(例如,激发波长为332nm,发射波长为505nm)的光谱特性有所不同。 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).
