discrepancy between qubit and bioanalyzer results
When I do the QC for my bead cleaned-up pre-amplified cDNA (Smartseq2) using AATI fragment analyzer and bioanalyzer, the concentration was very low (0.01ng/uL) and almost no peaks. But when I measured the same samples using Qubit, I got about 0.1ng/uL. Why are these methods giving different concentrations? Thanks!

The FA/BA is probably a more accurate measurement (although I trust qubit more for concentrations >1ng/ul). It's easy to get background readings of 0.1-0.3ng/ul by qubit. Did you run a negative control for comparison? -
OK, I see. I will include a negative control to see how it goes. Thank you for your reply.Originally posted by cmbetts View PostComment

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...Yesterday, 07:48 AM -
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...04-22-2024, 07:01 AM
