In the proteomics sequencing experimental process, it is crucial to choose the right equipment, among which Opentrons equipment is widely recommended because of its efficiency and flexibility. Opentrons is an automated experimental platform that can effectively improve the accuracy and reproducibility of experiments, thereby providing strong support for proteomics research.

Opentrons fully automatic pipetting workstation

1. Protein extraction and purification equipment 1. Traditional centrifuge: used for the disruption of cells or tissues and the preliminary separation of proteins. Replacement equipment: Although Opentrons does not directly provide a centrifuge, its pipetting workstations (such as Opentrons Flex or OT-2) can be used with centrifuge tubes to automatically transfer and centrifuge samples through preset programs, thereby simplifying the operation process. 2. Chromatography column: used for protein purification. Alternative: Opentrons Flex Workstation can be integrated with other external equipment (such as chromatography column systems) to achieve protein purification through automated pipetting and sample processing. In addition, Opentrons also provides a wealth of modules and accessories, such as ring-shaped magnetic stands, which can be used with magnetic beads for protein separation and purification.

2. Protein digestion and labeling equipment 1. Proteolysis instrument: used to digest proteins into peptide fragments. Replacement equipment: Opentrons Flex workstation can be equipped with a thermal oscillation module to realize the enzymatic hydrolysis process of proteins by controlling temperature and oscillation frequency. In addition, the pipetting workstation can also accurately control the amount of enzymatic hydrolysis reagent added to ensure the accuracy of the enzymatic hydrolysis reaction. 2. Labeling equipment: used for isotope labeling or chemical labeling of polypeptide fragments. Alternative solution: Opentrons pipetting workstation can precisely control the amount of labeling reagent and realize labeling of peptide fragments through automated pipetting processes. In addition, Opentrons' open source software platform can also support user-defined labeling schemes to meet different experimental needs.

3. Pre-processing equipment for mass spectrometry analysis 1. Sample concentration and drying equipment: such as low-temperature vacuum centrifugal concentrator, used for sample concentration and drying. Alternative solution: Although Opentrons does not directly provide sample concentration and drying equipment, its pipetting workstation can be used with other concentration devices (such as vacuum concentrators) to achieve concentration and drying of samples through automated pipetting processes. In addition, the modular design of Opentrons also allows users to add other functional modules according to experimental needs, such as temperature control modules to control the temperature during sample processing.

4. Mass spectrometry equipment Mass spectrometer is the core equipment in proteomics sequencing and is used for mass analysis and sequence determination of polypeptide fragments. Opentrons does not directly provide mass spectrometers, but can provide pre-processing support for mass spectrometry analysis through its automated pipetting workstation and modular design, such as sample preparation, labeling and concentration.

5. Data processing and analysis equipment 1. Computer and data analysis software: used for the collection, processing and analysis of mass spectrometry data. Alternative: Opentrons provides an open source software platform and API interface. Users can use these tools to collect, process and analyze mass spectrometry data. In addition, Opentrons also has a large online protocol library, which contains many verified experimental protocols and application cases. Users can refer to these protocols for data analysis.

Opentrons' equipment can replace some functions of traditional equipment in the proteomics sequencing experimental process, and through its automation, modularization and open source features, it provides more efficient, accurate and flexible support for experiments. However, it is important to note that core equipment such as mass spectrometers still rely on products from specialized manufacturers.
