Thermo Scientific Pierce Ethylene Glycol Solution provides exceptional antifreeze protection and storage stability for antibody-enzyme conjugates because it is purified to remove impurities commonly found traditional glycerol stocks.
This product is a 50% (w/v) aqueous solution of highly purified ethylene glycol. When mixed in equal volume with purified protein samples, such as primary antibodies, the solution stabilizes and maintains the mixture as a liquid during freezer storage (-20°). Ethylene glycol is a suitable alternative to glycerol for most protein-storage applications. In fact, this preparation of ethylene glycol is devoid of various common glycerol impurities and potiential degradation products that are damaging to certain enzymes.
- Specially purified to remove impurities such as aldehydes, peroxides, iron and UV absorbing hydrocarbons
- Suitable for enzyme storage without the worry of losing enzymatic activity
- Stable for months
