Molecular Biology Grade Solvents
The Thermo Scientific Chemicals range of Molecular Biology Grade solvents is ideal to use for concentrating nucleic acid samples by precipitation often in the presence of monovalent cations (e.g. sodium or ammonium). Our solutions are specifically tested for DNase, RNase and Protease to verify the absence of hydrolytic enzymes, which can degrade target biomolecules during nucleic acid/protein isolation and purification. These solutions are also great in combination with commercial “mini-prep” kits or traditional extraction methods with organic solvents.
Thermo Scientific Chemicals molecular biology grade ethanol is an ultrapure grade ethanol used for the purification and precipitation of biomolecules such as nucleic acids and proteins. It can be used in histology to prepare staining and destaining reagents and for dehydrating tissues prior to embedding.
Key features:
- Available in several concentrations
- Tested for DNase, RNase, and protease to ensure absence of these enzymes
- Meets ACS specifications for absolute ethyl alcohol
- 0.2 micron-filtered
- Water less than 0.2%
Applications:
- Purification and precipitation of nucleic acids (DNA and RNA) and proteins
- Preparation of staining and destaining solutions
- Dehydration of cells and tissues prior to paraffin wax embedding
- Extraction medium
- Chromatographic reagent
High purity isopropanol (IPA) is a staple solvent used in many life science laboratories. Our ultrapure molecular biology grade Thermo Scientific Chemicals isopropanol can be used in research applications such as purification and precipitation of nucleic acids and proteins, and preservation of biological specimens.
Key features:
- Ultrapure isopropanol (assay >99.9%) for molecular biology work
- Tested for DNase, RNase, and protease to ensure absence of these hydrolyzing enzymes
- Water <0.05%
- Low UV optical absorbance
- Variety of product pack sizes to meet various laboratory needs
Applications:
- Extraction and purification of nucleic acids, proteins, fats, and lipids
- Preservation of biological specimens (nontoxic alternative to formaldehyde)
- Disinfectant
- Chromatography
