We are new to ATAC-Seq. We have performed library validation and several of our samples have produced results similar to those in the image attached. We have a single large peak at 186 bp. Are we okay to go ahead for sequencing? Thanks a lot.

We run qc chips for people doing ATACseq with some frequency. I'm never sure what a "good" result is.
I guess you want a large percentage of your DNA to be in the nucleosome monomer size range? But you also want to see some multimers? Not sure.

Here is what my ATAC libraries look like. I agree that optimization of tagmentation enzyme amount or time should be considered.
What is you input amount? Are you starting with <50,000 cells? Smaller input amounts will require less enzyme and/or shorter incubation.Attached FilesLast edited by RickC7; 06-14-2018, 08:25 AM.

Does my library look ok?
Hello, I performed ATACseq preparation of librarys I used 50.000 cells counted by en bauer chamber, and following the protocol of Buen rostro, I did 25 cycles in total of PCR. Can someone tell me if this library looks ok? (attached pdf 1st sample) I am not sure about it. Thank you so much for your help
Best

Cancer research has been transformed through numerous molecular techniques, with RNA sequencing (RNA-seq) playing a crucial role in understanding the complexity of the disease. Maša Ivin, Ph.D., Scientific Writer at Lexogen, and Yvonne Goepel Ph.D., Product Manager at Lexogen, remarked that “The high-throughput nature of RNA-seq allows for rapid profiling and deep exploration of the transcriptome.” They emphasized its indispensable role in cancer research, aiding in biomarker...-
