An efficient wash step removes any contaminants that can produce false positives and the final low volume elution step produces highly concentrated functional protein. Rainin PureSpeed Protein Tips radically simplify purification of antibodies and recombinant proteins. This innovative approach produces the highest concentration of purified protein, allowing many options for downstream functional assays. Using the protein purification protocol offered on Rainins 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.
