Optimizing Protein Purification Conditions
12 Feb 2015PureSpeed Protein Tips have been demonstrated to be the most efficient and cost-effective way to purify recombinant proteins and antibodies. Used with the Rainin E4 XLS electronic pipette, PureSpeed's unique design allows bidirectional flow of the sample over the resin bed, which maximizes the capture of the target protein by allowing the binding reaction to reach equilibrium. This application note demonstrates that simultaneous screening of multiple conditions can be achieved rapidly and effectively using the PureSpeed system.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Pipettes and DispensersPipettes and dispensers are essential lab equipment used to dispense measured volumes of liquid accurately. Explore a range of manual and electronic pipettes, including single and multichannel, serological and volumetric pipettes, as well as a range of pipette tips. Bottle-top dispensers are also available for simple and fast solvent dispensing.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.
