Description

General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application

Le formamide déstabilise les duplex d′acides nucléiques et peut être utilisé, généralement à une concentration de 50 %, dans les protocoles d′hybridation nécessitant des températures d′hybridations plus faibles.
