| Title |
ChIP-seq input for H3K27ac in wild-type female 8-week-old mouse heart |
| Sample type |
SRA |
| |
|
| Source name |
heart
|
| Organism |
Mus musculus |
| Characteristics |
age: 8-week-old
genotype: wild-type
tissue: heart
chip antibody: input
|
| Treatment protocol |
To harvest tissues, 8-week-old mice were killed humanely by i.p. injection of an appropriate volume adjusted for body weight of sodium pentobarbitone (stock 200 mg/ml) pre-mixed at a 2:1 ratio with sodium heparin (stock 5,000 I.U./mL).
|
| Growth protocol |
Mice were bred and housed in individually ventilated cages and all animals had ad libitum access to water and food (Teklad #2918 global 18% protein rodent diet). Mice used were either wild-types (Pcca+/+ A138T; amWT) for control experiments, or homozygous (Pcca-/- A138T; amPA). Only heterozygous or wild-type dams were used for breeding and genotyping by PCR was performed.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
8-week-old mouse hearts were fixed for 10 min at room temperature with 1 % formaldehyde in modified AMVM isolation solution containing 0.5 mM EGTA (solution pH 7.4 at room temperature) in Langendorff mode. Fixed ventricles were minced and rinsed twice in PBS, then lysed in ChIP lysis buffer (1 % SDS, 10 mM Tris-HCl pH 8.0, 1 mM EDTA) by homogenisation (Qiagen TissueRuptor II). Lysates were pooled with fixed, sonicated Drosophila S2 cells at a ratio of 5:1 mouse:Drosophila cells, followed by IP.
DNA libraries were made using the NEBnext Ultra II DNA library preparation kit for Illumina (Cat no. E7645).
