Questions and Answers

What is the purpose of the optical module in real time PCR system?

  • To conjugate with a reporter fluorochrome
  • To detect fluorescence in the tubes during the run (correct)
  • To amplify and quantify a target DNA molecule
  • To translate fluorescence data into result

What is the function of TaqMan probe in real time PCR?

  • To bind to dsDNA and emit a fluorescent signal
  • To prevent the amplification of target DNA molecules
  • To emit fluorescence signal upon degradation by Taq polymerase (correct)
  • To detect and quantify soluble substances

In ELISA, what does a direct ELISA involve?

  • Coating microwell plates with antigen and quantitating labeled antibody binding (correct)
  • Conjugating a reporter fluorochrome with a quencher fluorochrome
  • Detecting and quantifying soluble substances such as peptides and proteins
  • Using TaqMan probe to emit fluorescence signal
