We study the role of cell wall hydrolases in the context of bacterial cell wall synthesis. To assess the biochemical activity of these cell wall hydrolases, I overexpressed and purified a protein (MepK) and subsequently isolated it using an affinity chromatography matrix called Ni-NTA matrix from Qiagen.

Experimental Design and Results Summary

Application

Purification of cell wall hydrolase and examine their biochemical activity on peptidoglycan.

Starting Material

E. coli cells overexpressing protein

Tips

Include 10-20 mM Imidazole in the lysis buffer to prevent non-specific protein binding.

Results Summary

I successfully purified my cell wall hydrolase, MepK, and subsequently demonstrated its biochemical activity on peptidoglycan. Moreover, I also established that MepK has a role in cell wall synthesis.

Summary

The Good

One-step easy purification.

The Bad

None.

The Bottom Line

I have used this product extensively during my graduate studies to purify many cell wall hydrolases as shown in the figure. Highly recommended.
