Advanced PhotoActivation System!

 The latest innovation in Viable PCR for detecting viable bacteria in environmental samples


 - PhotoActivation Systemdead organism의 DNA/RNA를 neutralizes 시켜, PCR, Flow Cytometry,

   Fluorescence Microscopy를 이용하여 living cells의 DNA/RNA선택적으로 Detection할 수 있습니다.


 - PhotoActivation System allows the activation of a photosensitizer (PS) by low doses of harmless visible

   light of an appropriate wavelength (blue, red, and yellow) to excite the PS to its reactive triplet state,

   which will then generate reactive oxygen species that are toxic to cells.      



Ethidium Monoazide (EMA)

  - Ethidium Monoazide (EMA) mono doses microtubes for individual sample treatment.

  - In the detection and enumeration of microorganisms in clinical samples, environmental or food

    control by molecular biology techniques it crucial to differentiate live cells from dead cells.  

  - Single dose tube Ready to use Dry reagent, no use of DMSO.

  - EMA will turn the applicability of genetic techniques and applications in many fields.



  This product has been formulated to meet the range of EMA concentration used

  in public scientific works, and contains EMA enough to treat 1000 μl of sample.

Sample ( μl)





If this volume of sample is used, the final EMA concentration would be 12,5 μM. .





If the application needs more concentration of EMA, reduce the sample volume accordingly

Reaction buffers

 - For combining with photo reactive dyes ( i.e Propidium or Ethidium Monoazide)

 - One of the critical steps in all viable cell detection workflow by the means of PMA or EMA

   photoreaction, is sample and reagent incubation on darkness.  
 During this treatment is very important to maximize reagent diffusion trough dead cells, spores,

   and cysts of microbial aggregates.

- On the other hand also is necessary to prevent viable cell damage, for this reason ionic strength,

  pH, nutrient level and aerobic/anaerobic balance needs to be under control.

 Models   These reaction buffers are compatible with vPCR, Flow Cytometry and Fluorescence Microscopy procedures.

 Reaction Buffer standardFor general purposes, neutral pH, standard ionic strength.

 Reaction Buffer plus

Contains anti clumping agents, cell membrane fluidising agents and a reduced level of nutrients.

Designed for stabilizing live cells but accelerating reagent diffusion trough dead cells.
Compatible with Enterobacteria and Mycobacteria.

 Reaction Buffer anaerobic

Contains anti clumping agents, minimum nutrient levels and provides a reducing environment compatible

with PMA or EMA based reagents. Designed for stabilizing anaerobic live cells but accelerating reagent diffusion

trough dead cells. Compatible with Bifidobacteriaceae

Reaction Tube

 - The optimal performance of photochemistry reactions is highly related with the amount of light
   received by the sample. In this product the optical properties of plastics and the tube alignment
   trough the PhAST platform have been considered in order to obtain the best-adapted solution. 

 - High transparent 1,7 mL snap cap micro- centrifuge tubes.

 - Optimal performance for PhAST Blue platforms.




 Light transmittance at 460 nm (%).


 GenIUL reaction tubes show the best light  transmittance at 460 nm (wavelength used for

 Propidium monoazide or Ethidium monoazide


 Compared with other suppliers these reaction

 tubes can obtain up to twofold better transmittance

 oven (3 min-750 W) 



 - Double dye technology in order to overcome the current limitations of viability PCR procedures.
   Nowadays, the paradigm is based in the cell membrane integrity of living cells as a unique
   differential factor from dead cells. However, as appointed in first reports, some treatment
   procedures can induce cells death without compromising membrane integrity.
-  This new reagent, combined with the appropriate reaction buffer, extends the concept of
   viability PCR to cells with intact cell membrane structure but also with capability to actively
   maintain bacterial homeostasis, as a result of active.

-  Combining both dyes with the correct reaction buffer, the DNA from dead cells (with damaged or not
   damaged membranes) will be neutralized; therefore only DNA from live cells will be detected by PCR.



 Feature   PEMAX™(Patent pending) - Reagent 2 vials of 0,5 mg   - 25 monodoses (TBC – Biomarker Kit)

  Double dye technology combines two photo-reactive molecules with different size and charge.

  The smaller molecule is capable of crossing cell membranes, but most of microorganism by the means of active efflux pumps, are able to revert

  this uptake. To allow the cells to maintain their homeostasis, are necessary larger incubation times and well defined reaction buffers.

  The second dye is needed to complete dead cell DNA neutralization when in the sample exist high amounts of dead cells.
