Web13 sep. 2012 · The Multiplex PCR 5X Master Mix is used at a final concentration of 1X in most cases; however, in some cases, the Multiplex PCR 5X Master Mix can be used as low as 0.8X or up to final 1.5X to increase product yields. Annealing temperature. Single-plex PCR should be first performed for each pair of primers, testing a gradient of annealing ... http://insilico.ehu.es/tm.php?formula=basic
WebWe've developed a NEB online tool, the NEB Tm Calculator, that can be used for any of our polymerases to get an appropriate Ta for your experiment. Our Tm calculator takes … Web30 dec. 2015 · The term 16.6*log 10 ([Na +]) adjusts the Tm for changes in the salt concentration ... No phosphate is present at the 5' end of strands made by primer extension, so no adjustment to the OligoCalc DNA MW calculation is necessary for primer extensions. That means that for ssDNA, ...
