We have a theory that large libraries, specifically those with fragments trailing off to >2kb, do not quantitate accurately from Bioanalzyer. We think this because qPCR concentrations do not correlate. Has anyone else had this problem? It seems if we are able to remove the "tail", then qPCR matches a bit better with Bioanalzyer.

Libraries over 2 kb don't tend to work on Illumina sequencers, so do you really care what the concentration of those molecules is?
Also, are you doing a TaqMan qPCR or SYBR? If it's SYBR, you have to factor in the average molecule size, so you're still dependent on the Bioanalyzer anyway.

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...-

Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...-
