检测原理 |
研究证实铁是生物体内量最多的过渡金属元素,其参与多种生理活动。近几年,细胞内的游离铁离子由于具有很高的反应性,和细胞损伤、死亡有一定的关联而得到了越来越多的关注。在细胞内游离铁离子以稳定的Fe2+和 Fe3+形式存在。从细胞内的还原环境、金属转运体及Fe2+的水溶性考虑,因此揭示细胞内Fe2+的行为比Fe3+更重要。
本试剂盒提供一种荧光探针可以和Fe2+特异性结合,探针可以很好的进入到细胞内部,适用于活细胞内Fe2+的检测。当探针与Fe2+反应后,可以生成一种不可逆的橙色(红色)荧光产物(激发波长:542 nm,发射波长:575 nm)。 |

Q1:如果实验处理中用到的药物也是一种铁螫合剂,试剂盒原理也是铁螫合剂,这样会不会存在一种竞争关系,导致检测的结果变化?
如果您的实验目的是验证这个药物(螯合剂)的作用,那就是可以用的。这个试剂盒的探针就是检测没有被螯合的铁离子,探针不会去抢已经螯合的铁。
Q2:亚铁荧光法试剂盒,该探针是否能够跟DAPI共染?
有文献记录该探针可以和DAPI共染
