Protein Expression and Purification Fast Protein Liquid Chromatography (FPLC) The ÄKTA explorer 100 Air from GE Healthcare Life Sciences is an FPLC system used for the purification of protein samples using low- and high-throughput applications. Gel Imaging System The ChemiDoc XRS+ System from Bio-Rad is a CCD high-resolution and high-sensitivity imaging system with fluorescence, colorimetry, densitometry, chemiluminescence, and chemifluorescence capabilities. LEX Bioreactor Epiphyte3's LEX ("Large-scale EXpression") bioreactor technology was developed at the Structural Genomics Consortium as an efficient, high-throughput method for growing E. coli cultures for protein expression. Ultrasonic Liquid Processors The VCX 130 and VCX 750 ultrasonic processors from SONICS are liquid processors for protein extraction from different cell cultures. Protein Columns Column Chromatography is a preparative technique used to purify compounds depending on their polarity or hydrophobicity. In column chromatography, a mixture of molecules is separated based on their differentials partitioning between a mobile phase and a stationary phase. High-Speed Centrifuges used to harvest microorganisms, viruses, mitochondria, lysosomes, peroxisomes and intact tubular Golgi membranes. The majority of the simple pelleting tasks are carried out in fixed angle rotors. High-Speed Centrifuges Shaker Incubators A temperature controlled biochemical instrument combining incubation and shaking functions.
