Rainin PureSpeed™ Protein Tips

New Rainin PureSpeed^™ tips enable you to purify up to 12 protein samples in just 15 minutes!

PureSpeed™ Protein Tips

Purifying native and recombinant proteins can be a complex process. Why not try a more simple method? Rainin's new PureSpeed™ Protein Tips have an affinity resin incorporated in the base of the pipette tip which captures, purifies and enriches the protein of interest by bidirectional flow of sample volume through the tip bed. PureSpeed^™ tips produce the highest concentration of purified protein, which enables many options for downstream functional assays.

Unlike traditional methods, PureSpeed^™ Protein Tips have a unique process that draws the sample repeatedly over a low dead volume, packed resin bed. This offers a controlled contact time with the resin and higher binding kinetics, an efficient wash step removes any contaminants to eliminate false positives. Finally the low volume elution step produces highly concentrated functional protein.

PureSpeed^™ Protein Tips are designed for use with the LTS version of the E4^™ XLS^™ electronic pipette. The E4^™XLS^™ has a dedicated PureSpeed^™ mode that enables protein purification to be programmed and controlled in a semi-automated process, simplifying and enhancing the performance of the tip.
