Product Name:

MegaX DH10B™ T1R Electrocomp Cells

Catalog Number:

C640003

We are interested in making a large volume of lenti vector plasmid for genomics study. The MegaX 10B competent cells were transformed with ligation mixture contain lenti vector with insert. This competent cells were selected for this high transformation efficiency.

Experimental Design and Results Summary

Application

Library preparation

Starting Material

Ligation mixture

Protocol Overview

We used 2ul of ligation mixture into 22ul of electro competent cells with 2Kv, 200 ohm condition and typically get 4.5-4.7ms pulse.

Tips

Purify the ligation mixture before electroporation

Results Summary

We got high transformants, however with lentiviral vector we observed recombined plasmids if grown more than 14hr at 37 celsius.

Additional Notes

Summary

The Good

High transformation efficiency

The Bad

Observed unwanted recombinant in lenti vector with large volume.

The Bottom Line

Recommended for high efficiency transformation for library making.
