Minute™ Protein Extraction Kits


Yes, it is possible to extract total protein from mammalian cells in just 1 minute!


The world's leading spin column based protein extraction kits



 The Minute™ series of protein extraction kits (patents pending) developed by Invent Biotechnologies, Inc. are excellent tools for rapid and easy protein extraction/isolation from a variety of species including but not limited to mammalian, marine animals, insects, plants and bacteria. Unlike any other protein extraction kit in the market, these next generation protein extraction kits employ optimized buffer systems coupled with state of the art proprietary filter cartridge technologies (spin column) for total protein extraction, cell fractionation, and membrane protein isolation. The kits offer numerous advantages over other competing products in terms of speed, ease of use and performance.

concentrate protein samples and remove buffer components






Quickly concentrate protein samples and remove buffer components

Afyon SDS-PAGE sample preparation kit is a fast, efficient way to concentrate protein samples and remove buffer components that may interfere with electrophoresis. In less than 10 minutes, samples are ready for SDS-PAGE or immunoblotting. 



  • Quickly remove contaminants that can interfere with electrophoresis (GuHCl, urea, Ammonium sulfate, etc)
  • Protein samples ready to load in less than 10 minutes
  • Safe and non-toxic - no DMSO required
  • Many times faster than concentration and buffer exchange via ultrafiltration or dialysis
  • Compatible with SDS-PAGE and downstream Western blotting

The novel ORCA Gel Electrophoresis unit and the corresponding VELUM Precast Gels offer the latest technique in terms of easy handling, resolution and reproducibility for up to 52 protein samples per unit and run.

Up to 4 ORCA Gel Electrophoresis units can be combined (one on top of the other) and run simultaneously.









ORCA Gel Electrophoresis routine

The ORCA routine is designed for daily protein analysis by SDS-PAGE, SAR-PAGE or IEF. Handling of the system including the correct setting of the corresponding VELUM gels or the electrodes does not require further user education.


ORCA Gel Electrophoresis research

The ORCA research offers maximum flexibility for research and development. This system allows for both, 1D gel electrophoresis ans 2D gel elctrophoresis (including Refraction-2D and 2D DIGE).


Pack your own LC/MS capillary columns

What’s the best way to dispense small-volume liquid samples in a controlled manner? Rely on the Next Advance Pressure Injection Cell. Often called a bomb loader, the Pressure Injection Cell is invaluable for two applications:

1. densely packing nanobore capillary columns with solid-phase particles for LC/MS;

2. precisely infusing microliter samples into mass spectrometers without additional transfers, wasted sample or contact with metallic surfaces which adsorb negatively charged molecules.
