  • Convenient Formats of Competent Cells

    NEB provides these superior competent cell strains in several formats for your convenience. All are available as 50 µl single-use transformation tubes and many are available in larger, 200 µl tubes for multiple simultaneous reactions. Our most popular cloning strains are available as electrocompetent cells. NEB 5-alpha is also available in a lower efficiency, subcloning format for substantial value.

    96-well, 384-well and StripWell formats may be customized upon request. Please inquire.
