Allele's Xtreme Efficiency Competent Cells are prepared with unique salt compositions and procedures that result in significantly higher transformation efficiencies than those prepared by traditional lab protocols using CaCl2 buffers. Chemically competent DH5α cells are suitable for a short transformation protocol in as little as 3 minutes before plating. Also, the cells are suitable for the propagation of plasmids of all sizes and preparations, and are recommended for difficult constructs that often yield low colony counts. Results have shown transformation efficiencies of up to 10^9 cfu/μg.
