Sample GSM4396046 Query DataSets for GSM4396046
Status Public on Mar 07, 2020
Title Input_HP1_3'RI_B3_1
Sample type SRA
 
Source name In vitro cultured blood stage cells
Organism Plasmodium falciparum
Characteristics genotype: AP2-Ggfp-3'RI
clone: B3
chip antibody: None
Growth protocol Blood stage P. falciparum parasites were cultured in human O+ red blood cells in RPMI-1640 medium supplemented with Albumax II (10% v/v), hypoxanthine (200 μM) and gentamycin (50 μg/ml) in 3% CO2 and 5% O2 at 37 °C.
Extracted molecule genomic DNA
Extraction protocol ChIP was performed as previously described (Zanghi et al, 2018 Cell. Rep.) with parasites synchronised at 36 hpi. Sonicated chromatin (500 ng DNA content) was immunoprecipitated overnight with 0.5 μg of anti-HP1 polyclonal rabbit antibodies. and incubated after with 25 μl of Dynabeads Protein G (Invitrogen) for two hours. Subsequent washing, cross-link reversion and DNA extraction were carried out as described before.
Sequencing libraries were produced with the immunoprecipitated DNA using the MicroPlex Library Preparation Kit v2 (Diagenode) with the KAPA HiFi polymerase (Kapa Biosystems) for the PCR amplification. For each ChIP sample, a control DNA corresponding to the ChIP input was processed in parallel.
