The TV400-DGGE Denaturing Gradient Gel Electrophoresis System

The TV400-DGGE denaturing Gradient Gel Electrophoresis system is a cost-effective solution for researchers studying mutations and DNA polymorphisms critical in disease aetiology and genetic diversity. Designed primarily for parallel denaturing Gradient Gel Electrophoresis (DGGE), where electrophoresis and the denaturing gradient run in the same direction, the TV400-DGGE has a maximum 96-sample throughput compatible with standard microplates and thermal cycler blocks. A 100ml gradient mixer is also included to pour gradient gels using our newly designed gel-running module and cam-caster, while a 400W heater, regulated by an external temperature control unit connected to a heat sensor within the gel tank, allows the gel temperature to be set to the predetermined melting temperature (Tm) of the PCR®-amplified DNA polymorphism or mutation of interest.

400W heating element - manually controlled by a temperature control unit connected to a PT100 heat sensor - enables the gel and buffer temperature to be set in 1°C increments to a predetermined Tm, to a maximum 70°

Maximum 96-sample throughput using two 48-sample combs - allows samples to be transferred quickly and easily to the each gel from standard 96-well microplates or thermal cycler blocks
Large format 20.5 x 20cm glass plates allow gradient gels to be poured containing wider ranges of denaturant concentration, maximising sensitivity and resolution
100ml gradient mixer used with the new-style TV400-GRM and casting base to make two 1mm parallel denaturing gradient gels
Formamide, urea and acrylamide available to pour denaturing gradient gels - contact
Can also be adapted for constant denaturing gel electrophoresis (CDGE) if the denaturant concentration required for partial melting of the DANN target sequence is already known
