PEG300 (Polyethylene glycol 300) is a water-miscible polyether widely used in biochemistry, structural biology, and medicine in addition to pharmaceutical and chemical industries. It serves as a kind of solubilizer, excipient, lubricant, and chemical reagent. PEG300 helps in the formation of hydrogels in situ upon mixing with silk. These PEG–silk hydrogels are of interest for many biomedical applications, such as anti-fouling and anti-adhesion.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
