DNA/RNA Isolation

Pure nucleic acids are essential starting materials for molecular biology methods: gene-expression analyses require pure RNA and genomics methods require pure genomic DNA. The quality of purified RNA or DNA is critical for successful molecular biology.

Of the many manual and automated methods available for RNA and DNA purification, spin-column kits are the most frequently used. These kits provide fast and convenient purification of nucleic acids for all demanding applications.

Qualitative nucleic acid purification kits are used for recovering high amounts of pure material and require little hands-on time. Universal kits allow purification from different sources, including cells, tissues, blood, bacteria and plants. Source-specific kits typically allow higher yields and purity.

biotechrabbit continuously expands its nucleic acid purification portfolio with new universal column-based and source-specific kits.
