| Treatment protocol |
We established the Cas12a stably expressing HUDEP-2 using pRG232 (#149723, Addgene) and puromycin selection. Control and NFIA&NFIX Cas12a gRNA oligos were subcloned into lentiviral pRG212 (#149722, Addgene) using BsmBI restriction site, and then introduced into HUDEP2 cells by lentivirual infection
|
| Growth protocol |
HUDEP2 Cells were maintained in a medium containing StemSpan SFEM (9650, StemCell Technologies) supplemented with 50 ng/mL recombinant human stem cell factor (300-07, Peprotech), 3 IU/mL Epoetin alfa (Epogen, Amgen), 0.4 μg/mL dexamethasone (D9891, Sigma Aldrich), 1 μg/mL doxycycline (D9891, Sigma Aldrich) and 1% Pen-Strep (15140122, Invitrogen). Erythroid differentiation was induced by placing 2-5 million HUDEP-2 cells into 1x Iscove’s modified Dulbecco’s medium (IMDM, MT10016CV, Mediatech) supplemented with 1% L-glutamine, 330 μg/mL human holo-transferrin (T4132, Sigma Aldrich), 10 μg/mL recombinant human insulin solution (I9278, Sigma Aldrich), 2 IU/mL heparin, 5% inactivated fetal biovine serum (FBS), 3 IU/mL Epoetin alfa (Epogen, Amgen), 1 μg/mL doxycycline and 1% Pen-Strep.

| Extraction protocol |
0.5-1 million undifferentiated HUDEP2, HUDEP2 undergoing 2 days of differentiation, and primary cells undergoing 8 days of erythroid differentiation were used for CUT&RUN. We followed the experimental procedure published by Henikoff lab (dx.doi.org/10.17504/protocols.io.bcuhiwt6) with adaptations15. Antibody incubation was performed in 300μl PCR tubes for 2 hours in the cold room. pA/G-MNase and Spike-In DNA (#40366) were obtained from Cell Signaling. The following antibodies were used: IgG (#3900, Cell signaling), BCL11A (ab191401, Abcam), NFIA (PA5-52252, Thermo Fisher Scientific), NFIX (SAB1401263, Sigma Aldrich), GATA1(Ab11852, Abcam), H3K27Ac (MA5-23516, Invitrogen). All antibodies were used approximately 1μg in 100μl.
The concentration of the released DNA fragments was determined by Qubit and 15-30ng DNA was used for adapter ligation and library construction. The sequencing libraries were generated using the kit from NEB (Cat# E7645 and E6440S). We followed the experimental procedure posted by Nan Liu (dx.doi.org/10.17504/protocols.io.wvgfe3w) to size select the <120 bp fragment and facilitate the transcription faction binding site identification20. The multiplexed sequencing libraries were pair-end (2x50bp) sequenced on Illumina Nextseq 2000 platform.
