Enhancing Specificity and Sensitivity in 14;18 Translocation Assay Techniques

This quiz focuses on the intricacies of the 14;18 translocation assay, emphasizing the roles of blocking and washing in enhancing specificity and sensitivity. Participants will explore additional factors contributing to assay specificity beyond these techniques. The importance of stringency washes will also be evaluated, specifically regarding the denaturant used and its function in the wash solution. Furthermore, the impact of adding an alkaline phosphatase tag to oligonucleotide probes on melting temperature (Tm) during hybridization will be discussed.

Presentation Transcript

  1. Molecular Diagnostics – Quiz 11 • Blocking and washing both contribute to the specificity and sensitivity of the 14;18 translocation assay. What else contributes to the specificity? • In the stringency wash you will do today, what is the denaturant that is added to the wash solution and why is it being used? • How and why does the addition of the alkaline phosphatase tag to the oligonucleotide probe effect the Tm when the probe is used in hybridization? (Be specific)
