Denaturing gradient gel electrophoresis (DGGE) systems

DGGE is a powerful genetic analysis technique that can be used for detecting single base changes and polymorphisms in genomic, cloned, and PCR amplified DNA. DGGE is ideal for screening samples for genetic mutations, and it can also be used for determining DNA fragment melting point.

Design of the gel cassettes allows both sides of the glass plates to be continuously exposed to the circulating temperature controlled buffer, so minimising temperature fluctuation within the gel/sample matrix and improving gel resolution
Hinged safety cover with an electrical interlock protects against accidental contact with charged buffer, aids temperature control and limits evaporation
Buffer tank dimensions allow efficient use of bench space
No need for an external peristaltic pump for buffer recycling

The DGGEK-2401 has a medium-sized buffer tank but with two dual gel cassettes, for a capacity of four gels per run.

Note: Power supply is not included.
