Using the protein purification protocol offered on Rainin’s E4 XLS electronic pipette, PureSpeed tips offer a convenient, low-cost method of purifying micro-scale volumes of target protein in as little as 15 minutes. PureSpeed tips are supplied in clamshells containing 12 tips each and are available with three resin types: ProA and ProG, for antibody purification; IMAC for recombinant proteins.

PureSpeed accessories facilitate use of the PureSpeed tips and E4 XLS pipette and allow purification to be performed up to 12 channels at the same time, when used with an E4 XLS multichannel pipette. The accessory kit contains several components which can also be ordered individually.
