Product Introduction

PluriSIn 1 (NSC 14613) is an inhibitor of stearoyl-CoA desaturase (SCD1), the key enzyme in oleic acid biosynthesis, revealing a unique role for lipid metabolism in hPSCs.
Kinase Assay
SCD1 activity assays: Cells are plated in 6-well plates at a density of 50k to 100k cells per well. 24 h later, 20 μM PluriSIn #1 or 0.2% DMSO-control are added to the cells. After 12 h of incubation at 37 ℃, 5% CO2, the old medium is removed, cells are washed with PBS, and new medium containing 2.3 μM of 0.75 UCi [1-14C] Stearic Acid is added. The cells are incubated for up to 4 h at 37 ℃, 5% CO2. After the incubation period, the medium is discarded and the cells are washed 3 times with 2 mL of PBS. 2 mL of the mixture n-hexane: isopropanol (3:2 v:v) are added, and the cells are incubated for 30 min at 37 ℃, 5% CO2. 2 mL Folch solution (chloroform: methanol,2:1,v:v) are subsequently added. The liquid is transferred to tubes for phase partition by adding 1 mL water. The lower organic phase is evaporated and used for lipid saponification and TLC separation of the free [1-14C] Stearic Acid (substrate) and [1-14C] Oleic Acid (formed product). Lipids extracted from the cells are applied to TLC plates previously immersed in 10% NO3 Ag and activated at 120℃x60 min. Unlabeled stearic and oleic acid are added to each application point as carriers and as internal standards for identification. The plates are run with a solvent mixture of Chloroform:MeOH:AcH:DDW (90:8:1:0.8). The free fatty acids are detected by U.V. after spraying the TLC with a 2',7',dichlorofluorescein solution. The spots corresponding to stearic and oleic acid are scraped and the radioactivity counted in a sc intillating counter. SCD1 desaturase activity is calculated from the percent conversion of substrate to product and the conversion to pmol/min/106 cells.
Cell Research
Relative cell numbers are determined by fixating the cells with 0.5% glutardialdehyde and staining with methylene blue dissolved in 0.1 M boric acid (pH 8.5). Color extraction is performed using 0.1 M hydrochloric acid, and the staining (which is proportional to cell number) is quantitated by measuring absorbance at 650 nM.(Only for Reference)

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
