In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.08 mg/mL (2.38 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Ensayo celular ^[1]	Cells are plated in 96-well plates containing complete medium and cultured for 24 h. Then cells are treated with Methyllycaconitine citrate at the indicated concentrations for specified times. After drug treatment, cell viability is measured by MTT assay. Briefly, 10 µL of the MTT solution (5 mg/mL) is added to each well and incubated for 4 h at 37°C. After removing the supernatant, 100 µL DMSO is added into each well. The absorbance is measured at 570 nm with a microplate reader. All experiments are repeated 3 times^[1]. MCE no ha confirmado la precisión de estos métodos independientemente.

Administraciòn de animales ^[2]	Adult male Swiss CD-1 mice are used in all experiments. They are housed at 22±1°C under a 12-h light/dark cycle with free access to food and drinking water. Climbing behavior is measured. Briefly, mice of 20 to 26 g are intraperitoneally administered saline (5 mL/kg) or Methyllycaconitine citrate (MLA) (6 mL/kg) at the beginning of the test. Twenty minutes later, the animals receive a single dose of saline or methamphetamine (METH) (1 mL/kg) subcutaneously and are placed individually, for habituation, into the experimental chamber consisting of a cylindrical cage with the wall made of plastic bars and covered with a lid. After a 20-min period of exploratory activity, stereotypy measurement is performed for a period of 30 min^[2]. MCE no ha confirmado la precisión de estos métodos independientemente.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
