The NAP DNA Purification Columns, NAP-25, 50 Pack (17085202) are disposable size exclusion columns for gravity-flow purification of oligonucleotides and small DNA fragments. They are prepacked with Sephadex G-25 DNA Grade and support samples up to 2.5 mL for desalting, buffer exchange and removal of unincorporated nucleotides.
Key Features:
- Gravity-flow purification, requiring no pump or positive pressure during operation
- Prepacked Sephadex G-25 DNA Grade matrix, supplied ready for gel filtration workflows
- Suitable for oligonucleotides and small DNA fragments, including DNA greater than 10 bp
- Maximum 2.5 mL input sample volume, matching the NAP-25 column size for larger sample volumes in the NAP range
- High DNA recovery, with verified yield or recovery greater than 90%
- Low recovered salt contamination, typically less than 3% after purification
- Pack of 50 columns, suitable for repeated research purification workflows
Note: This product is designed for research use only.
