FastPrep-24™ 5G Homogenizer

Catalog Number:

116005500

In this study, we examined the expression levels of cell wall hydrolases in Enterococcus faecium using Western blot analysis. We utilized the FastPrep-24™ 5G Homogenizer to efficiently lyse the Gram-positive bacterial cells, which facilitated high-quality protein extraction suitable for the immunodetection of our target proteins.

Experimental Design and Results Summary

Application

Used for efficient mechanical lysis of Enterococcus faecium to extract total cellular proteins for downstream Western blot analysis of cell wall hydrolases.

Tips

Use appropriate bead types for optimal disruption of tough Gram-positive cell walls. Always balance tubes to avoid uneven homogenization and machine wear.

Summary

The Good

Extremely effective for lysing difficult-to-break gram-positive bacteria.

The Bad

Plastic tubes can crack if improperly loaded or overfilled, leading to sample loss. Requires optimization of speed and time settings for different sample types, which can be time-consuming initially.

The Bottom Line

The FastPrep-24™ 5G Homogenizer is a powerful and reliable tool for disrupting tough bacterial samples like Enterococcus faecium, making it ideal for protein extraction and Western blot workflows.
