  • Concentrates 500 µL down to 15 µL
  • Concentration factor 25 x to 30 x
  • High sample recovery (greater than 90% of dilute starting solution)
  • Fast processing time - 10 to 30 minutes
  • Consistent recoveries thanks to the reverse spin capability
  • Reverse spin capability provides consistent recoveries

 

 

 

Applications

 

  • Concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms
  • Purification of macromolecular components found in tissue culture extracts or cell lysates
  • Primer removal, PCR cleanup, removal of linkers or macromolecular labels from a reaction mix, and protein removal prior to HPLC
  • Desalting, buffer exchange and protein dialysis
  • Size exclusion and protein fractionation

Material Supplied

The Amicon Ultra-0.5 device is supplied with two microcentrifuge tubes. During operation, one tube is used to collect filtrate; the other tube is to recover the concentrated sample.

Desalting or Diafiltration

Desalting, buffer exchange or diafiltration are important methods for removing salts or solvents in solutions containing biomolecules. The removal of salts or the exchange of buffers can be accomplished in the Amicon Ultra-0.5 device by concentrating the sample, then reconstituting the concentrate to the original sample volume with any desired solvent. The process of "washing out" can be repeated until the concentration of the contaminating microsolute has been sufficiently reduced. See example below.
