Rainin offers high-speed protein tips

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.

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, a 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 E4XLS electronic pipette.

The E4XLS has a dedicated PureSpeed mode that enables protein purification to be programmed and controlled in a semi-automated process.
