Product Information
| Description: | Polyethylenimine is a surfactant that acts as a polyelectrolyte multilayer on a charged surface, providing that surface with a biocompatible coat. |
| 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. |
