@Pete_Brahms@SecKennedy This article for Fauci is interesting in this context Rethinking next-generation vaccines for coronaviruses, influenzaviruses, and other respiratory viruses: Cell Host & Microbe
@cshperspectives It looks like they used an antibody from a different company than at least some of the previous papers. Even if it was from the same company, maybe previous batches didn't cross react. In previous manuscripts, only a subset of ZnF143 sites overlap with CTCF.
It's been a while since I posted. Pleased to announce 2 papers! Both about chromatin compartments.
Using deep sequencing in collaboration with ENCODE, we identify A and B compartments at 500 bp resolution! #3Dgenome@NatureComms

See Thread.
@dphansti You should change the title of the paper to "If you need to draw black lines to show people where the domains are, then you need to sequence more"
My 3 year old daughter Lila was recently diagnosed with a VERY rare and aggressive type of #leukemia.
👉 It’s potentially treatment resistant… AND
👉 Requires a bone marrow transplant.
A🧵with all the details we have so far 👇
Please @Twitter help me save my little girl.

More proof that there are two types of TADs forming by different mechanisms. Using "TAD" to refer to both of them is confusing.
3/ The right way for you to show that the results are due to cfDNA is to purify 100,000 sperm, isolate the cfDNA from this prep, and then do ATAC-seq or Hi-C. What do you see? Probably nothing because there is not enough cfDNA
1/ Of course we didn't use DTT. It makes no sense to try to analyze the state of chromatin by first destroying it with DTT. You are contaminating the sperm with DNA from the epididymis by mincing the tissue, which we don't do.
2/ In the conditions we use, the nuclei are permeabilized based on movement of dyes into the nucleus. The DNA is extracted after ATAC-seq by proteinase K and phenol extraction, which you don't seem to do according to the manuscript.
Maybe you are not purifying the sperm properly? We don't find any cell free DNA in sperm preps from the cause epididymis and no differences between treating or not with DNase. Also, no difference with ejaculated sperm after gradient purification
