生物活性
PMQA (Zn-green) 是一种基于 8-aminoquinoline 的比率荧光传感器，显示了 Zn2+ 诱导的辐射红移 (85 nm)。PMQA (Zn-green) 是一种具有细胞膜通透性的荧光探针，适用于活细胞中的 Zn2+ 检测。体外研究
After incubation with PMQA (20 μM) for 1 h, weak green fluorescence appeared, presumably caused by the probe capturing intracellular zinc from its native ligands since PMQA has high affinity for zinc.
The response of PMQA to Zn
2+
can be reversed by N,N,N’,N’-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) or EDTA.
When the stock solution of PMQA (0.1 mM in Tris Buffer) is kept at room temperature for a week, there is no significant loss of PMQA determined by HPLC analysis.
