Preparation of Yeast Samples with Cryo Mill

Experimental Purpose:

This experiment aims to utilize a cryo mill for efficient grinding of yeast liquid to break cell walls while preserving protein activity, providing a solid foundation for subsequent protein extraction. By leveraging an ultra-low temperature environment and advanced 3D grinding technology, the method ensures complete cell disruption while preventing heat-induced protein inactivation. The results will evaluate the method's effectiveness in enhancing protein extraction efficiency and maintaining protein integrity, delivering high-quality samples for further experimental analysis.

Experimental Steps:

Material Preparation

Prepare a 2mL*24 adapter and the required yeast liquid samples. Ensure that all experimental equipment, grinding beads, and adapters are clean and contamination-free.

Sample Loading

Add an appropriate amount of yeast liquid to a 2mL centrifuge tube, along with an equal volume of mixed grinding beads (0.5mm and 1mm). Ensure the ratio of grinding beads to the sample meets experimental requirements, then securely cap the centrifuge tube.

Adapter Setup

Place the centrifuge tube into the corresponding hole of the 2mL×24 adapter. Ensure the groove at the bottom of the adapter locks firmly into the shaft slot. Adjust the adapter to a horizontal position and place the centrifuge tubes symmetrically. Cover the adapter with the lid and tighten the nut securely.

Set Grinding Parameters

Configure the grinding machine to a frequency of 70Hz and a grinding time of 60 seconds, with a 10-second pause. Perform 5-8 cycles, adjusting the time and cycles as needed based on the number of samples and desired grinding results.

Grinding Process

Start the grinder to initiate the grinding process. Pause and adjust the grinding time if necessary to ensure complete cell disruption.

Final Check

After grinding, inspect the samples to confirm thorough cell disruption before proceeding with subsequent steps.

This method efficiently disrupts yeast liquid samples, preserves protein activity, and provides high-quality samples for subsequent analysis.
