Agarose Channel

(QMAC)

Bacteria immobilization in a thin agarose channel suitable for

•  microscopic imaging for cellular analysis

•  diffusion of media for bacteria growth and antibiotics for susceptibility testing 

 

 

QMAC technology is implemented in multi-well plate formats with dried antibiotics
as ready-to-use kits for susceptibility testing

•  96-well for dRAST (direct Rapid Antimicrobial Susceptibility Test)

•  24-well for QDST (Drug Susceptibility Test for M. tuberculosis)

Sample + Agarose

Dried antibiotics

Media

Immobilization of bacteria cells in the agarose channel

Diffusion of culture medium and antibiotics into the agarose channel

 

Time-lapse imaging

  • Each QMAC Chip enables time-lapse imaging of bacteria growth

  • Precise cellular image analysis and algorithms for determination of the minimum inhibitory concentration

  • S/I/R interpretation based on breakpoint and expert rules
