Description:

WARNING: This product is for research use only, not for human or veterinary use.

DMNB is a photolabile H+-donor that releases acid when excited at 405 nm. It has been used for fluorescence imaging in conjunction with the pH sensitive fluorescent probe cSNARF1 to study nuclear proton dynamics, acid venting from cancer cells, and hemoglobin-restricted diffusion in the cytoplasm of red blood cells.

Product Data
Biological target:
DMNB (6-Nitroveratraldehyde), a precursor, can be used for the synthesis no-carrier-added 6-[18F]fluoro-L-DOPA (6-FDOPA).
In vitro activity:
By imaging the spread of H+ ions from a photochemically-activated source (6-nitroveratraldehyde), DCO2 in human RBCs was calculated to be only 5% of the rate in water. Reference: Sci Rep. 2016 Oct 25;6:36018. https://pubmed.ncbi.nlm.nih.gov/27777410/

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.

Preparing Stock Solutions
