We got linearized plasmid pSB1C3 and we performed gel extraction successfully and the nanodrop protocol showed that we got 12.7 ng/µl concentration of plasmid.

Transformation of Bacillius subtilis 168 with pGFP-rrnB containing yneA

Aim

We performed gel electrophoresis on our 12 digested minipreps and found 8 were the correct product. We transformed B. subtilis 168 with one of the samples (1).

Filamentous in pgfprrnb.jpg

Materials and Protocol

Please refer to transformation of B. subtilis.

Results and Conclusion

Please refer to results in tomorrow's lab book.
