I'm having a lot of issues with NuGEN's Ovation 3'DGE and RNA-Seq library preparation kits. No matter what I do, I can't seem to generate any libraries for sequencing. Has anyone had a similar problem? When I use the mRNA Seq prep kit from Illumina and try it on the same samples I'm getting great libraries....hmmm.....frustrated....

are you using Illumina kit to generate library itself, or your own reagents? Anyway, there is a report in Biotechniques that shows that pretreatment of ovation-generated ds cDNA with S1 nuclease increases efficiency of library generation. Their claim is that it's due to hairpins at the ends of DNA fragments that obviously would affect any end repair /adaptor ligation. S1 ligase will get rid of the ssDNA, so should solve the problem.

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 -
Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.07-01-2026, 11:43 AM
