PMA-Lite LED Photolysis Device is specifically designed for photoactivation of propidium monoazide (PMA) and other similar dyes. It can also function as a general photolysis device to provide continuous illumination to 1.5-2 mL-sized vials in a controlled manner. The device can hold up to 18 vials. Multiple LED lights are positioned to provide even and maximal illumination from both the sides and bottom to all vials. An internal fan is used to reduce the heat generated from the lights to ensure near room temperature photolysis. The device has a timer that can be set for 10, 15, 20 or 30 minutes of continuous photolysis. The unit has 120/240V internal converter. A universal outlet adapter is included for customers outside of North America.
PMA is a photo-reactive dye that binds to dsDNA with high affinity and can be used for the selective detection of viable pathogens by qPCR. More information can be found on our PMA product pages 40019 and 40013.

For viability PCR of gram-negative bacteria we highly recommend using our new PMA Enhancer (31038) in conjunction with PMA. PMA Enhancer for Gram Negative Bacteria was designed to improve PMA-mediated discrimination between live and dead gram-negative bacteria. When a sequence from a gram-negative bacteria is amplified by PCR, samples pre-treated with Enhancer show a decrease in the signal from dead cells, with no change in the signal from live cells.
Biotium also provides strain-specific PMA Real-Time PCR Bacterial Viability kits with validated primers for 5 selected pathogens: M. tuberculosis, S. aureus, MRSA, Salmonella, and E. coli O157:H7. These kits provide everything that you need for the selective detection of your favorite species of live bacteria by real-time PCR. Don’t see your favorite strain?
