Help with trouble shooting: re-reading the same plate produces better results
Hello, I'm doing Sanger sequencing and I'm getting some strange results that I've now reproduced at least 4 times. Every time I read my plate in the sequencer, my results look much better when I read it again the following day with absolutely no modifications to the plate. That is, multiple wells that were once negative and didn't show any signal, suddenly showed up as positive for my target on a re-read of the same plate on the next day. I'm using the BigDye xterminator kit with m13 primers after PCR. I'm also reading my plates on the 3730 DNA analyzer.
Does anyone know why this could be happening? I am at a complete loss as to what is going on.
Thanks in advanceTags: None

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
