Description

MAX Efficiency® Stbl2™ Competent Cells are high-efficiency chemically competent cells specifically designed for cloning unstable inserts. In addition to recA1, a unique set of genetic markers allow for stable cloning of direct repeat and retroviral sequences and tandem array genes. MAX Efficiency® Stbl2™ Competent Cells offer:

• >1 x 109 transformants/µg plasmid DNA for cloning rare sequences
• Elimination of mcrBC-hsdRMS-mrr and mutation of mcrA—allows cloning of methylated genomic sequences
• A unique genotype that stabilizes direct repeat and retroviral sequences such as SIV and HIV
• Greatly increased plasmid yield and quality due to endA1 mutation
For Research Use Only. Not for use in diagnostic procedures.
