PCR Cycling Parameters–Six Key Considerations for Success

WebThe most sophisticated T m calculations take into account the exact sequence and base stacking parameters, not just the base composition (1,2,3). The equation used is: T m = Δ H kcal ∘ C × Mol Δ S + R In ( [primer] / 2) − 273.15 ∘ C. Δ H is the enthalpy of base stacking interactions adjusted for helix initiation factors (3,4). WebNOTE: The PCR inhibition spike control samples will contain a final volume greater than 50 L due to the extra spike volume unless the spike volume is substituted for water in the master mix. 6.6 Ensure that the proper final pmol concentration of primers and probe is added per reaction based on the assay-specific attachment. totfact https://htctrust.com
