Meridian Core Reagents include a range of high-quality products for routine molecular biology applications, including electrophoresis, cloning and protein digestion.


Meridian electrophoresis reagents include agarose and buffers. The DNase/RNase free agarose is available as powder or pre-weighed tablets and is ideal for high resolution separation of a wide range of DNA/RNA fragments. To complement this are a selection of pre-weighed and ready-to-use running and loading buffers. These products have been specially developed for convenience, efficiency, and to help standardization of nucleic acid and protein electrophoresis.

  • Perfect for DNA and RNA electrophoresis
  • Molecular biology grade
  • Dissolve and use in minutes
  • Guaranteed batch-to-batch reproducibility


Meridian offers a range of products to complement our Competent Cells. They consist of ligase, for use in vector construction and X-Gal and IPTG, used in the blue/white selection of transformed colonies.

  • Maximize transformation efficiency and selection
  • Convenient and time saving
  • Sterile, ready-to-use



Protein Digestion

Proteinase K is an enzyme used to digest most proteins in molecular-biological techniques. The enzyme may be used at 56°C for up to 4 hours, or 37°C for overnight incubations. Proteinase K is available as a powder or as a stabilized stock solution (20 mg/ml). Proteinase K solution is stabilized with a specially formulated buffer and can be used directly from the freezer.

  • Broad-spectrum serine protease
  • Active under denaturing conditions
  • Stable at high temperatures
  • Molecular biology grade
