Publicly available brain tissue (any part) Histone (H3K27me3 and H3K4me3) ChIP-seq samples

Question

[EagleEye]

Hello everyone,

I am looking for H3K4me3 and H3K27me3 ChIP-seq (Illumina) samples for human brain tissue samples (FASTQ, any region of brain). I need greater than 36 bp read length or atleast 50 bp read length samples with proper input (control). I could not find it on Roadmap & ENCODE. Kindly please let me know if there are any samples available.

Thanks.

There are some from human on ENCODE. Check if they fulfill your criteria.

All those samples are either 36 bp read length or embryo samples (looking for adult brain). Anyway thank for the effort :)

Have you tried SRA-Explorer for a search. Posting small samples below. H3K4me3[All Fields] AND brain[All Fields] AND ("Homo sapiens"[Organism] OR ("Homo sapiens"[Organism] OR human[All Fields]))?

Thanks for the information. Looks like SRR2172598 and SRR2172599 are not publicly available (they are protected under dbGAP). Still struggling to get H3K27me3 ChIP-seq.

There was a much larger list that you may need to look through. I only copied a few entries.

I will have a look :)
