I know that this post is dead for 3 years now, but I had the same problem and I know that many people are looking for an answer. What they are telling me is that tagmentase is an extremely labile enzyme and it is enough for it to be a little bit outdated or to have several freeze-thaw cycles to lose most of its activity. Hence very large library sizes - tagmentation is just not good enough, and increasing its duration will not help because the enzyme is inactive. Better switch to other methods of DNA shearing.

Eh? Who are the "they" to whom you refer? Nextera doesn't seem particularly labile to me.Originally posted by rudzik79 View Post
One point of possible confusion: after tagmentation, but before PCR, everything tends to look very big because the Tn5 has inserted but apparently it still tethering both DNA ends to each other. See here for more details:
This paper describes a "contiguity preserving transposition based sequencing" method that takes advantage of this behavior of Tn5.

Yes, I think it is possible that rudzik79 did not read the entire thread prior to posting. Which one could understand, I suppose. But in this case led to an erroneous assumption as to the "aliveness" of the thread...Originally posted by GenoMax View PostReally Last posting in this thread was on 20th April of this year by @fanli

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.
There is no single reason why many patients don’t respond to treatment as expected. Cancer is...07-08-2026, 05:17 AM
