PCRing Antibiotic Resistance Markers

  • May 25, 2010
PCRed the antibiotic resistance marker biobytes (Ampicillin, Tetracycline and Chlormaphenicol) that are analogous to the kanamycin PCR fragements.

Production of BioByte Parts:

Parts are created by PCR, digested with BsaI, and put into the parts plasmids as demonstrated by mWasabi.
