Description

General description

The SIG10 5a Chemically Competent Cells share the most useful genetic elements of standard cloning strains like DH5α and directly replace them in cloning protocols.
They provide the performance researchers need with ease of use as only common laboratory equipment is required and provide solutions for a wide range of applications at economical prices.

Features and Benefits

• Direct replacements for standard cloning strains like DH5α, DH10B, JM109, TOP10, XL1-Blue, etc.
• Optimized genetics for high yields: endonuclease and recombination minus
• Blue - white screening

Components

• SIG10 5a chemically competent cells
• pUC 19 transformation control DNA
• recovery medium for cloning
