Large or Ligated DNA

These competent cells offer the highest transformation efficiencies available, enabling dramatically improved transformation efficiencies when cloning large plasmids and ligated DNA. XL10-Gold Ultracompetent Cells possess the high transformation phenotype (Hte), which gives these cells an average transformation efficiency of ≥ 5 x 109 transformants/μg of supercoiled DNA and makes them ideal for the transformation of large plasmids and ligated DNA. They can also be used for the construction of plasmid libraries as they are able to decrease the size bias against large plasmids and they can produce larger and more complex libraries. ElectroTen-Blue Electroporation-Competent Cells possess the high electroporation efficiency phenotype and have an average transformation efficiency of ≥ 3 x 1010 transformants/μg of supercoiled DNA.
