SDM1 Forward Primer for pCT5c Mutation

Description

This primer is designed for mutating the BsaI site 1 in pCT5-bac 2.0. This part is a forward primer with a mutation nucleotide, changing c to g.

Usage and Biology

• This part is used in site directed mutagenesis of pCT5c (Part: BBa_K4417000).
• Sequence: tgccctgggtttccattgcgc
• Length: 21-mer
• Tm: 61℃
• GC content: 62%

Method

This part is used with BBa_K4417000 and BBa_K4417002. A detailed protocol is described in BBa_K4417000.

Characterization

This primer will remove one BsaI site, leaving another two BsaI sites. The KLD product was transformed into DH5-α, and the plasmid was checked using a diagnostic digest. From Figure 3, the expected band size can be identified in lanes 2, 7, 11, and 15.

Conclusion

This part has high efficiency and quality in site directed mutagenesis.
