Purity

>70% double-stranded covalently closed circular form I (RF I) DNA.

Transformation Efficiency

  • E. coli: >2 × 105/µg DNA
  • B. subtillis: >2 × 10/µg DNA (by electroporation)

Transformation efficiency of competent B. subtillis largely depends on the percentage of dimerized pHY300PLK vector. To increase transformation efficiency, first amplify pHY300PLK DNA with an E. coli recA+ strain.

Prior to electroporation of B. subtillis, amplify vector with an E.coli recA- strain to obtain monomeric pHY300PLK.

 

Concentration

300–800 µg/ml

E. coli-Bacillus Shuttle Vector | pHY300PLK

Form

10 mM Tris-HCl (pH 7.4), 0.1 mM EDTA

Vector Size

4,870 bp

The E.coli-Bacillus Shuttle Vector pHY300PLK is constructed from the E.coli-derived plasmid pACYC177 and the Streptococcus faecalis-derived plasmid pAMa1; as a result, the vector can be used to transform both E. coli and Bacillus subtillis. The E. coli-Bacillus Shuttle Vector DNA contains both the ampicillin resistance and tetracycline resistance genes as selective markers; while both of these resistance genes can be expressed in E. coli, only the tetracycline resistance gene can be expressed in B. subtillis. The pHY300PLK vector also contains a single cleavage site for restriction enzymes Bal I, BamH I, Ban I, Bgl I, Bgl II, Bst P I, EcoR I, EcoR V, Hind III, Hpa I, Sal I, Sma I, Pvu I and Xba I.
