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 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (7.32 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[1]

hCOX1 or hCOX2 is preincubated with COX2-IN-2 in 0.1 M Tris-HCl buffer containing 2 μM hematin and 5 mM L-tryptophan at 30°C for 5 min, followed by a 5 min incubation with arachidonic acid. The enzyme reaction is stopped by the addition of 1 N HCl. The PGE2 formed is extracted with EtOAc and measured by RIA[1].

Animal Administration
[1]

Rats: Ten male Sprague Dawley rats are used per group. A suspension of 0.5% brewer's yeast in 0.5% methyl cellulose is injected into the right hind paw. The pain threshold us determined 3h after yeast injection. COX-2-IN-2 is given orally 2 h after yeast injection. The pain threshold in the treated rats are compared with that in the control rats[1].

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.
