Proteus X-Spinner 2.5

Easy Ultrafiltration of Membrane Proteins

The ultrafiltration unit Proteus X-Spinner 2.5 is the first centrifugal concentrator designed with membrane proteins as a key application.

The 2.5 ml non-stick UF concentrator provides the highest possible protein recoveries.
This is due to two factors: the low protein binding cellulose triacetate (CTA) membrane and critically, the design of the X-Spinner which ensures that ultra-filtration is in opposite direction to the centrifugal force.

Features:

  • Available MWCOs:
    5 kDa, 10 kDa, 20 kDa, 100 kDa and 300 kDa
  • Sample volume: 0.1 - 2.5 ml
  • Sample Recovery Rate: > 99%
  • g force: 2,500x g (swing bucket rotor) and
    2,000x g (fixed angle rotor)

The contra design also ensures that the filter does not clog (see Fig.)

 

 Ideal for:

  • Membrane proteins
  • Viscous sample, e.g. proteins stored in
    10 - 15% glycerol
  • Hydrophobic proteins, e.g. fibronectin
  • Protein fractions after size exclusion (SEC) or immobilized metal affinity chromatography (IMAC)
  • De-proteinization of blood and serum samples

New Application Note:
ICPL™ - Coupled Immunoprecipitation
(ICPL-IP)

ImmunoPrecipitation (IP) is widely used as a method to selectively isolate protein complexes from primary tissues. However, due to lack of specificity and selectivity of most antibodies and unspecific binding of the carrier beads, the method can produce false positives. The ICPL approach, employing stable isotope labelling and mass spectrometry, can discriminate true positive from false positive IP complexes.
