72oC 2min

All Biobytes essential gene primers were produced using Vector NTI. Each primer's thermodynamic properties were examined using Vector NTI's hairpin and dimerzation programs. Primers were optimized to fit as many of the following criteria as possible: 

  * Find the shortest possible sequence, reducing the cost to produce the primer.

  * Produce the highest score value possible.

  * Produce the closest Tm's possible

  * Produce hairpins with dG values >-5

  * Produce dimers with dG values >-10

The following are Vector NTI statistics for this primer:

dG Dimer (kcal/mol): -5.2

dG Hairpin (kcal/mol): -2.5

Oligonucleotides were synthesized. Primers were tested using MG1655 E.coli genomic DNA as template.
