OT-2 magnetic bead protein purification workstation

1. Early preparation 1. Equipment inspection: Make sure that the OT-2 magnetic bead protein purification workstation is in good working condition, and check whether all components are complete and functional. 2. Reagent preparation: Prepare the required magnetic beads, buffers, washing solutions, eluents and other reagents, and ensure that their quality and purity meet experimental requirements. 3. Sample processing: According to the experimental needs, the sample is preprocessed, such as cell disruption, precipitation removal, concentration, etc., to release the required protein.

2. Binding of magnetic beads to target protein 1. Magnetic bead selection: Select appropriate magnetic beads based on the properties and characteristics of the target protein. The surface coating and chemical composition of the magnetic beads should have specific binding ability to the target protein. 2. Mix the magnetic beads with the sample: Mix the pretreated sample with the magnetic beads, and incubate them under appropriate conditions (such as temperature, pH value, ionic strength, etc.) to fully combine the magnetic beads with the target protein. 3. Magnetic separation: Use the magnetic separation function of the OT-2 magnetic bead protein purification workstation to separate the magnetic beads bound to the target protein from unbound impurities and interfering substances.

3. Washing and Elution 1. Washing: Use appropriate buffer to wash the magnetic beads bound to the target protein to remove unbound impurities and interfering substances. During the washing process, the number of washing times and the volume of washing liquid should be controlled to ensure the washing effect. 2. Elution: Under the optimized elution buffer conditions, the target protein is eluted from the magnetic beads. During the elution process, the volume, elution time, and elution speed of the eluate should be controlled to ensure efficient recovery and purity of the target protein.

4. Collection and detection 1. Collection: Collect the eluted target protein and transfer it to an appropriate container. 2. Detection: Use protein quantitative methods (such as BCA method, Bradford method, etc.) to detect the concentration and purity of the purified protein. At the same time, SDS-PAGE, Western blot and other methods can be used for further analysis and identification of the purified protein.

5. Storage and subsequent application 1. Storage: Store the purified protein under appropriate conditions (such as temperature, pH value, light, etc.) to prevent its degradation or inactivation. Typically, purified proteins can be stored in a -20°C or -80°C refrigerator. 2. Subsequent application: According to experimental needs, the purified protein will be used for subsequent biological experiments, structural analysis, functional research, etc.

The workflow of the OT-2 magnetic bead protein purification workstation may vary depending on experimental requirements, the nature and characteristics of the target protein, and other factors. Therefore, during the specific experimental process, the workflow should be adjusted and optimized according to the actual situation. At the same time, to ensure the accuracy and reliability of experimental results, good experimental operation and quality control principles should be followed.
