Description

General description

Sulfuric acid 95-97% (EMSURE^®, ISO) is commonly used in regulated and highly demand lab applications such as quality control and production (except pharma GMP).

Application

• A systematic investigation of key factors of nucleic acid precipitation toward optimized DNA/RNA isolation.: This research examines the use of 2-Propanol in the precipitation of nucleic acids, optimizing conditions for DNA and RNA isolation procedures in molecular biology (Li et al., 2020).



• Staining of RNA and DNA on electrophoretic gels and in cytology with juice of Vaccinium myrtillus berries.: Utilizes 2-Propanol in the staining process of nucleic acids on gels, enhancing visibility and differentiation of RNA and DNA bands (Ahokas, 2019).
