Spin-column-based protein extraction / cell fractionation – a big leap for protein research

For the first time ever, the tasks that used to be tedious, lengthy, and unpredictable can now be performed by just a couple of quick spins using a tabletop centrifuge, delivering unsurpassed speed, convenience, consistency, and accuracy by eliminating uncontrollable variables associated with traditional solution-based procedures.

Invent Biotechnologies is the inventor of spin column-based protein extraction and cell fractionation. They successfully developed the Minute™ series of protein extraction and sub-cellular fractionation products.

The Minute™ Benefits:

  • Super-fast (as quick as 1 minute)
  • Small sample size
  • Complete profile
  • Unaltered endogenous baseline
  • All living organism and tissue types

The Minute™ Applications:

  • Protein trafficking/translocation
  • Protein-protein interaction
  • Protein modification
  • Signal transduction
  • Daily protein analysis
