Objectives in purifying and identifying biological material such as DNA, RNA, antibodies, etc.:

• Rapid isolation of DNA or RNA, e.g. from viruses such as SARS-CoV-2
• Sensitive detection of proteins, such as antibodies against bacteria and viruses, by blotting (Northern, Western and Southern blots)
• Easy production of diagnostic test systems for detecting infectious diseases via DNA, RNA or proteins
• Contamination-free specimen carrier for detection reactions with enzymes or antibodies (impregnation), e.g. allergy tests
•  

For critical applications of this kind, the high-quality filter media from Hahnemühle offer:

• Absolute purity of the raw papers used for highly sensitive test procedures
• Reliable yield in the purification of DNA/RNA using glass fibre filters
• Good paper wet strength during blotting after gel electrophoresis
