AUTOMATED OPENTRONS LOADING PROTOCOL WITH EVOTIP PURE
Complete, automated end-to-end sample loading on the Opentrons OT-2 through a layered sandwich approach with defined airgaps between the layers. The sandwich is pushed through the Evotip with the OT-2 pipette for 100 seconds leaving the sample safely stored and ready for injection on the Evosep One.
The automated sample loading protocol sequentially deposits 15 µl solvent A, 20 µl sample, and 150 µl solvent A to facilitate equilibration, loading, and desalting followed by storage, respectively.
On-robot Evotip loading requires an Evotip Loading kit (OT-2) (EV1164) and allows for full end-to-end sample processing on the Opentrons without manual intervention.
Stand-alone automated Evotip loading has been converted into an easy-to-use HTML form, that generates a complete python script for use in the Opentrons app, allowing the user to load from 8 to 288 Evotips in a single run.
END-TO-END SAMPLE PREPARATION WITH OT-2 PROTEIN ON-BEAD DIGESTION AND EVOTIP LOADING
Three end-to-end workflows utilizing protein aggregation capture and Evotip loading. They all contain steps with aggregation-based protein capture on magnetic beads, clean-up, and digestion as well as seamless Evotip loading based on layered sandwich approach.
The protocols have been converted into an easy-to-use HTML form, that generates a complete python script to use in the Opentrons app. It allows the user to process from 8 to 192 samples in a single run.
One workflow is designed to handle any type of reduced and alkylated cell lysate. Two workflows are designed for the analysis of unprocessed plasma. One generates samples for the analysis of neat plasma, while the other utilizes Mag-Net enrichment for deep plasma proteomics.
