Vivacon® 500
Reproducible DNA sample desalting and concentration
Vivacon® 500 centrifugal concentrators offer the optimal solution for DNA concentration and buffer exchange applications. For optimal performance with very dilute samples, e. g. forensic samples, Vivacon® 500 is equipped with the patented regenerated cellulose membrane Hydrosart®. High recoveries and excellent reproducibilities are paired with convenience offered by volume graduation and molecular weight cut-off printed on individual devices.
Vivacon® 500 can be used as well for concentration and buffer exchange of protein samples.
Vivacon® 500 Applications
- DNA rebuffering of organic extraction samples before sequencing reaction
- Dye removal after sequencing reaction
- Primer removal
- Plasmid concentration
- Protein concentration
- Protein rebuffering
For larger volumes up to 2 ml Vivacon® 2 with identical features is available.
Applications
- DNA rebuffering of organic extraction samples before sequencing reaction.
- Dye removal after sequencing reaction.
- Primer removal.
- Plasmid concentration.
