Edit Request: Page Rewrite edit
Hello,
I've made numerous minor edits to this page to make it conform with Wikipedia's style, and I also added a "cleanup" template message at the top to encourage others to continue improving the page. But since this a low priority page according to WikiProject Molecular and Cellular Biology and WikiProject Computational Biology and therefore doesn't receive much attention, I took it upon myself to rewrite the page to remove promotional and overly technical language. However, I have a conflict of interest and cannot ethically make edits myself. Therefore, I kindly request that another replace the content on the page with the content below. You'll notice that besides removing inappropriate language, I did not add any new information, except citations and crosslinks where they were lacking.
- @Cglife.bmarcus: Thank you for your handling of this and your note on the WP:MOLBIO talkpages. I'll go through your suggestions section-by section. T.Shafee(Evo&Evo)talk 08:38, 9 September 2019 (UTC)
Here is my full rewrite:
ATAC-seq edit
ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing) is a technique used in molecular biology to assess genome-wide chromatin accessibility.[1] In 2013, the technique was first described as an alternative advanced method for MNase-seq (sequencing of micrococcal nuclease sensitive sites), FAIRE-Seq and DNase-Seq.[1] ATAC-seq is a faster and more sensitive analysis of the epigenome than DNase-seq or MNase-seq.[2][3][4]
Done nothing controversial in these suggestions. T.Shafee(Evo&Evo)talk 08:42, 9 September 2019 (UTC)
Description edit
ATAC-seq identifies accessible DNA regions by probing open chromatin with hyperactive mutant Tn5 Transposase that inserts sequencing adapters into open regions of the genome. [2][5] While naturally occurring transposases have a low level of activity, ATAC-seq employs the mutated hyperactive transposase.[6] In a process called "tagmentation,"Tn5 transposase cleaves and tags double-stranded DNA with sequencing adaptors.[7] The tagged DNA fragments are then purified, PCR-amplified, and sequenced using next-generation sequencing.[7] Sequencing reads can then be used to infer regions of increased accessibility as well as to map regions of transcription factor binding sites and nucleosome positions.[2] The number of reads for a region correlate with how open that chromatin is, at single nucleotide resolution.[2] ATAC-seq requires no sonication or phenol-chloroform extraction like FAIRE-seq;[8] no antibodies like ChIP-seq;[9] and no sensitive enzymatic digestion like MNase-seq or DNase-seq.[10] ATAC-seq preparation can be completed in under three hours.[11]
- Done Some repetitious material removed, and sensible wikilinks added. Reasonable additional references. T.Shafee(Evo&Evo)talk 09:10, 9 September 2019 (UTC)
Single-cell ATAC-seq edit
Modifications to the ATAC-seq protocol have been made to accommodate single-cell analysis. Microfluidics can be used to separate single nuclei and perform ATAC-seq reactions individually.[11] With this approach, single cells are captured by either a microfluidic device or a liquid deposition system before tagmentation.[11] [12] An alternative technique that does not require single cell isolation is combinatorial cellular indexing. This technique uses barcoding to measure chromatin accessibility in thousands of individual cells; it can generate epigenomic profiles from 10,000-100,000 cells per experiment.[13] But combinatorial cellular indexing requires additional, custom-engineered equipment or a large quantity of custom, modified Tn5. [14]
- Done I agree with the suggestions. The above suggestion also replaces a lot of the promotional language with a far more neutral summary of the info and the cells-per-experiment range is clearer. T.Shafee(Evo&Evo)talk 10:08, 9 September 2019 (UTC)

Request edit edit
 | This edit request by an editor with a conflict of interest has now been answered. |
- User:Evolution and evolvability, thank you for your timely and considerate addition of my edits to the page. I also intended to delete the Efficiency and Specifications section. You'll notice I pulled some of the language from that section up to the Applications section, so there is now some repetition. The rest of the section, I believe, is promotional and does not not conform with Wikipedia's guidelines. Therefore, I request that you delete the Efficiency and Specifications section. Thank you, Cglife.bmarcus (talk) 14:53, 9 September 2019 (UTC)
Reply 12-SEP-2019 edit
Section deleted
- The requested section was deleted.
Additional changes made:
- Two instances where
{{cite journal}}was used were changed to{{cite book}}, as the references listed were their own publications covering a specialized area of information and published in editions (as are textbooks), rather than typical journals which publish on a regular schedule and which usually cover discordant topics (linked by a category) under sequential volumes and issues.
