Fast Protein Liquid Chromatography (FPLC) Systems (X2)

Fast protein liquid chromatography (FPLC) is often used to analyze or purify mixtures of proteins. The ÄKTApurifier FPLC system is a fully automated liquid chromatography system designed for protein purification, characterization, and collection, wherein proteins of various sizes can be readily purified using different kinds of columns. In addition, this system is also ideal for lipoprotein-based, liposome-based nanoparticle purification.

​​

There are two ÄKTApurifier FPLC systems in the facility. Both systems are equipped with UV, pH, and conductivity detectors. The purified samples are collected through an automated fraction collector. In addition, one system is equipped with an autosampler for automated sample injections. The facility also provides several types of prep grade columns for the FPLC systems.

​

Specifications and Features:

  • UV spectral range: 190 to 700 nm

  • Multiple wavelength detection: up to 3

  • Conductivity range: 1 µS/cm to 999.9 mS/cm

  • pH range: 0 to 14 pH units

  • Collection tube format: 12 mm (i.e. 15 mL falcon tube), 18 mm, 30 mm, 96-well microplates.

  • Flow rate: 0.001 to 10 mL/min

  • Injection volume: maximum 5 mL

  • Columns available in the facility: HiLoad XK 16/70 Superose 6 pg and HiLoad 16/600 Superdex 200 pg

Optima™ XE Ultracentrifuge

Ultracentrifugation is a method used to separate species within a solution according to density. Because of its "ultra" speed, ultracentrifugation are commonly used in molecular biology, biochemistry, and cell biology to separate molecules with very small density differences. Applications of ultracentrifuges include the separation of small particles such as viruses, viral particles, proteins and/or protein complexes, lipoproteins, RNA, and plasmid DNA. It can also be used for the purification of nanomedicine.

​

The Optima™ XE ultracentrifuge from Beckman Coulter is an integrated ultracentrifugation unit that is simple to use, increases productivity, and reduces error. It is equipped with intelligent user interface, multi-layered BioSafety features, and provides energy efficiency.
