This instructable describes how to make a blue LED (470nm) transilluminator for DNA imaging using SYBR safe dyes. The transilluminator has a 6 x 7 cm viewing area for small agarose gels.
The transilluminator can also be modified to sit beneath the mini-gel electrophoresis tank
(from a previous instructable), as described in Step 8. Used in this way, you can also visually track progress of your DNA during electrophoresis. Open source hardware kit
- This is an open source hardware project. To enable users to make or modify the device, I have included all of the PCB design files, enclosure design files and list of all hardware and electronics in a zip file attached below. We have also put together an LED Transilluminator Kit
containing all of the parts described in this Instrucatble.
