설명

일반 설명

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.

애플리케이션

Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.
