Wing disc, HP1a-chromo, HiC, rep1 |
| Sample type |
SRA |
| |
|
| Source name |
wing disc
|
| Organism |
Drosophila melanogaster |
| Characteristics |

tissue: wing disc
developmental stage: 3LW
|
| Growth protocol |
Stocks were maintained on standard cornmeal food at 25˚C. H3.2HWT and H3.2K9R larvae were cultured as previously described in Penke 2016. Briefly, one hundred fifty yw; ∆HisC, twi-Gal4/CyO virgin females and seventy-five yw; ∆HisC, UAS-2xEYFP/CyO; H3.2HWT/ H3.2HWT or H3.2K9R/ H3.2K9R males were put in a cage and allowed to lay eggs on a grape juice agar plates. GFP-positive L1 larvae were transferred to vials of standard food and allowed to grow at 25˚C. Wandering third instar (L3) GFP-positive larvae were used for experiments. HP1acontrol and HP1achromo larvae were cultured by establishing vials with ten w1118; Df(2L)BSC228/CyO, Tb, RFP virgin females and, to produce HP1acontrol, a single yw; +; + male, or a single w1118; HP1achromo/CyO, Tb, RFP male (Table S3). After three days, genomic DNA from sacrificed w1118; HP1achromo/CyO, Tb, RFP males was sequenced to confirm the genotype the HP1achromo allele, which exhibits occasional instability. The remaining females were flipped daily and non-tubby third larval instar wandering females were used for experiments.

| Extraction protocol |
Each in situ Hi-C replicate was performed using 60 wing imaginal discs dissected from female H3.2HWT, H3.2K9R, HP1-chromo, and HP1-control wandering L3 larvae. Discs were fixed in 1xPBS with 4% paraformaldehyde for 20min, transferred to tubes in a minimal volume of 1xPBS plus 0.15% Triton X-100, and used as input for the Arima Hi-C kit v00 protocol (A410030), following manufacturer’s instructions that were last revised March 2018.
Hi-C libraries were amplified using the KAPA Hyper Prep kit (KK8502).
