Company:

Promega

Product Name:

Pure Yield Plasmid Midi Prep

Catalog Number:

A2495

Our lab regularly uses promega midi prep kit for large scale plasmid isolation from 100-200ml bacterial culture for transfection. We observed the quality of plamid DNA good enough for transfection. We usually get 100-300ug plasmid depends on the culture density.

Experimental Design and Results Summary

Application

Plasmid DNA for transfection grade

Starting Material

Bacterial culture

Protocol Overview

Bacterial culture (100-150ml) grown overnight was pelleted down and resuspended in 3ml of resuspension buffer completely. Then resuspended cells were added with 3ml of cell lysis buffer and mixed gently a few times. The cells suspension transition to transparent (not more 3 min) add 5ml of Neutralization buffer and mixed gently 10 times to completely neutralize lysis buffer. We followed the manual protocol as recommended by Promega.

Tips

Allow lysis step for a maximum of 3 min and mix very gently

Results Summary

We observe high quality transfection grade plasmid in large volume.
