Hi tired_of_overclustering
I've had to do quite a lot of troubleshooting with MiniSeq libraries so I can try to help!
How are you purifying your libraries? And if you do a melt curve at the end of the qPCR, how does it look?

Puh... hard to say... MiniSeq as far as I know uses unpatterned flow cells so over clustering is definitely more of an issue then with patterned flow cells. Did you have a look at what was the difference in the decent runs and the over clustered ones? How do you determine loading concentration and what concentrations did you load? I guess you are aware of Illuminas Denature and Dilute Guide? Whats the average library size? What kind of libraries are you preparing? Do you see a difference with different library types (for example RNAseq vs WGS)?

Miniseq run issues
Hi,
I am new to sequencing stuff by myself and till date I have ran at least 30 miniseq runs. Some runs were decent, but most of the runs over clustered in spite of quantifying libraries using NEB library quant kit. I make my own libraries using two sets of PCR and custom designed barcodes, purify and run bioanalyzer. Is there a way to troubleshoot what is exactly wrong? I did contact Illumina and they haven't given me a satisfactory answer ever. Any help would be appreciated.Tags: 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...-
