In addition to the polyclonal ISPs, Torrent also filters low quality and primer dimer reads, and the “usable sequence” is the percentage of Library ISPs that pass the polyclonal, low quality, and primer dimer filters. The low quality filter eliminates reads with uncertain base calls; at least...
What informations can be determined from examining an electrophoretic gel of PCR products? Explain. Explain the Ct value in PCR. What should the Ct values of a negative control be from an RT-PCR? What are the probable reasons for getting a smudged effect when ...
If the user clicks the "Multiplex PCR dimer scores" button, PrimerMapper also implements a combinations without replacements algorithm (n choose k: equation 1) for all primers (both forward and reverse) to calculate cross-complementarity primer-dimer scores. The user must start with "1: Design...
Samples compromised by primer-dimer reactions were deleted from the analysis. Using a value of 17 femtograms per haploid genome of S. cerevisiae, we calculated Saccharomyces genome equivalents (SGE) per μL of extract volume.Abbreviations BSA: Bovine Serum Albumin ITS: Internal Transcribed Spacer...

2. Analyze reaction products (10 μL) by electrophoresis on a 3.5% high resolution agarose gel in 1X TAE stained with dye for detecting dsDNA. Gene specific sncRNA amplicons should form discrete ~75 bp bands that are easily distinguished from smaller primer-dimer bands that may be seen in ...
Shown in figure 1C) is the primer-dimer formation between the primers ACTAGTACGTAGATCATTCG and GCATCTACCAGCGATAGCTA. Note the 3' end of the second primer has a run of seven straight matches to the first. The scores for each of these is based on the formula 4 * |G + C| + 2 ...
gel filtration buffer increased to 1000 and 500 mM, respectively, we obtained nsp8 dimer and nsp8 tetramer. Based on our findings, we speculate that, the reason for Biswal et al. not detecting nsp8 tetramer through gel filtration might be that the NaCl concentration in the purification ...
In contrast, the success rate of LNA-spiked primers is 70% when dimer formation is ignored and 80% when accounting for putative primer dimer formation [15]. Although the primer design data set for both DNA and LNA-spiked primers are limited, the difference suggests that DNA primers may ...
Before proceeding to empirical testing, the finally selected primer sequences were checked for potential hairpins structure, self-dimer, cross-dimer, and cross-homology, and tested for binding affinities to the priming sites (delta G values) using Gene infinity Platform. Their specificity was ...
