NucPE1 Nuclear Peroxy Emerald 1

产品介绍

NucPE1 (Nuclear Peroxy Emerald 1) 是核定位荧光过氧化氢探针, 其特异性定位于细胞核，没有附加的靶向部分。储存方式：避光。

生物活性

NucPE1 (Nuclear Peroxy Emerald 1) is a nuclear-localized fluorescent hydrogen peroxide that is specifically localized to cellular nuclei without appended targeting moieties. Storage: protect from light.

体外研究

NucPE1 features two major visible region absorptions (λ_abs=468 nm, ε=27,300 M^-1cm^-1; λ_abs=490 nm, ε=26,000 M^-1cm^-1) and a weak emission (λ_em=530 nm, Φ=0.117). Reaction of NucPE1 with H₂O₂ triggers a fluorescence increase upon its conversion to fluorophore NucPE1, which possesses one major absorption band at 505 nm (ε=19,100 M^-1cm^-1) with enhanced emission (λ_em=530 nm, Φ=0.626). NucPE1 selectively accumulates in the nuclei of a variety of mammalian cell lines as well as in whole model organisms like C. clegans, where it can respond to subcellular changes in H₂O₂ fluxes.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

NucPE1 maintains the ability to selectively target nuclei in vivo. NucPE1 imaging reveals a reduction in nuclear H₂O₂ levels in worms overexpressing sir-2.1 compared to wildtype congeners, supporting a link between this longevity-promoting sirtuin protein and enhanced regulation of nuclear ROS pools.

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

1.

请依序添加每种溶剂： 10% DMSO 40% PEG300 5% Tween-80 45% saline
Solubility: ≥ 2.5 mg/mL (5.17 mM); Clear solution

此方案可获得 ≥ 2.5 mg/mL (5.17 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。
将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液
