Descripciòn

PEG400 is a strongly hydrophilic polyethylene glycol used as an excellent solvent for a large number of substances. PEG400 is widely used in a variety of pharmaceutical formulations.

In Vivo

Treatment of Fischer 344 rats with PEG400 at a constant volume of 1.0, 2.5 or 5.0 mL/kg body weight/day 5 days/wk for 13 week does not result in any mortality attributed to chemical toxicity or changes in haematology or clinical chemistry findings[1].
Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
The final concentration of PEG300 can go up to 50% in the formulations for intravenous and intramuscular injection without any toxic effects. In PEG400 based solubility-enabling formulations in oral delivery of lipophilic drugs, both the 60% and the 100% PEG-400 formulations allowed full solubilization of the dose throughout the entire gastrointestinal tract-like journey[2][3].

Administraciòn de animales
[1]

Rats[1]

Fischer-344 rats (10/group/sex) are administered polyethylene glycol 400 (PEG400) by gavage at 1.0, 2.5 or 5.0 mL/kg (1. l, 2.8 and 5.6 g/kg, respectively) body weight/day 5 days/wk for 13 wk. Animals in the control group receive water by gavage (5.0 mL/kg body weight/treatment day). An additional 10 rats/sex/group are assigned to the control and high-dose groups for a 6-wk recovery period. Evaluation of potential renal toxicity is identified as a primary objective[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.
