Product Information
| Description: | Polyethylene glycol 20000 (PEG 20000) is a polymer formed by condensation reaction of ethylene oxide and water. Polyethylene glycol is used for the isolation of plasmid DNA and the precipitation of phage. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
