Transfer membrane ROTI®Nylon plus
Ideal for DNA/RNA-transfers.
ROTI®Nylon plus is a cationic, einforced nylon 6.6-membrane with extremely high tensile strength. The positively charged membrane surface guarantees rapid and efficient binding of DNA and RNA. May be steam sterilised.
Also available in convenient pre-cut sheets of standard gel size!
Nucleic acids can be cross-linked to the membrane by baking (80 °C, 15 min) or through UV exposure. No cross-linking is required for alkaline transfer as the negatively charged DNA forms a very stable complex with the positively charged ROTI®Nylon membrane.
Detection systems: radioactivity, chemoluminescence, fluorescence
Application examples:
- Southern and Northern blot
- Dot-Blot
- DNA fngerprinting
- Macro- and Microarrays
