ALA-1/4, 4-channel fluorometer


ALA-1/4 is the first multi channel rotor type fluorescence detector that allows detection of the fluorophores lights emission in the reaction mixes with a closed-tube method immediately after PCR.

ALA-1/4 is a four-channel high speed detector of fluorescence/quenching ration of DNA probe combined with a fluorescence/quenching molecules. Level of fluorescence depends on the quantity of the positive  amplification after thermocycling of DNA probes. The instruments substitutes for electrophoresis and gel-documentation step of amplicon detection. The closed-tube method ensures biosafety conditions in the DNA diagnostic Labs.

Biosan FEP (Fluorescence  detection with End Point analysis) is the revolutionary approach that allows to:

  • Carry out the experiment with closed test tubes, thus eliminating the probability of contamination;
  • Perform the amplification and detection processes in the same room with reduced personnel costs;
  • 4-channels detection: FAM, HEX, ROX, CY-5;
  • Register, interpret and store the results obtained on PC;
  • Simultaneously detect a variety of infections pathogens;
  • Eliminate the need for electrophoresis and gel run storing instruments.

Channels' specifications:

  • Channel 1 — FAM:
    Excitation wavelength   460 nm
    Emission wavelength   515 nm
  • Channel 2 — HEX:
    Excitation wavelength   532 nm

    Emission wavelength   670 nm

Software specifications:

  • Register, interpret and store the results obtained on PC
  • Simultaneously detect a variety of infections pathogens
  • Save/Load the previously obtained results
  • Edit existing or create new test-systems
  • Option for results interpretation in gel electrophoresis image simulation
