Solvent & Solubility
DMSO : 130 mg/mL (300.04 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Protocol
HEK293 cells are plated into 96-well tissue culture plates at a density of 300 cells per well in the presence or absence of 50 nM mitomycin C (MMC) for 24 hours at 37°C, 5% CO2. Media is subsequently replaced with fresh media containing 0.5% DMSO plus RI-2 for an additional 24 hours. RI-2 is then removed, and cultures are allowed to grow to a 50-70% confluence. Average survival from at least three replicates is measured using CellGlo reagentor. RI-2 is deemed successful in sensitizing cells to MMC if they generate significantly greater toxicity in the presence of MMC relative to the absence of MMC. Specifically, sensitization is scored as a “+” when non-overlapping standard errors are observed for at least two pairs of compound doses[1].
