Description of NEP

NEP (VDP-green (NEP)) is a turn-on fluorescent probe based on the intramolecular charge transfer (ICT) mechanism for sensing vicinal dithiol-containing proteins (VDPs). NEP is exhibits high selectivity toward VDPs in live cells and in vivo and displays a strong green fluorescence signal (Λex/Λem=430/535 nm). NEP has the potential for parkinsonism[1].

NEP (1-30 μM; 6 hours) has no or little cytotoxicity in HepG2 and PC12 cells[1]. NEP (10 μM; 4 hours) causes the fluorescence intensity to decrease gradually in PC12 cells pretreated with 6-OHDA (0, 50, 100, and 200 μM; for 30 min)[1]. NEP contains a dithiarsolane moiety (five-membered As-S ring) as the receptor of VDPs. In the presence of VDPs, NEP displays a strong green fluorescence signal produced by the cyclic dithiarsolane cleavage and subsequent intramolecular cyclization to liberate the fluorophore. NEP maintains a reliable fluorescence response within the range of pH 7-10[1].

NEP (10 μM; for 4 h) causes the obvious green signal in zebrafishes (4 day old)[1].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
