Zfh1 ChIP-seq in Drosophila melanogaster embryos at 4-6h and 6-8h AEL

ABSTRACT: Canton S flies (as wild type) were bred at 25C and tightly staged 2-hr embryos were collected after 2 times of 2-hr prelay. The embryos were aged on the apple juice plates and aged to 4-6 and 6-8 hr. For each time point, two independent Chromatin immunoprecipitation (ChIP) experiments were performed using two different antibodies and compared to two independent mock ChIPs using the corresponding pre-immune serum. One Zfh1 antibody was generated in Guinea pig against full-length Zfh1 in the Furlong laboratory, and the other was a generous gift from Dr. Ruth Lehmann. ChIPs were optimized using the enrichment of a binding site identified in a pilot experiment of Zfh1- ChIP-on-chip measured by real-time PCR as previously described. The quality of each IP was also assessed by real-time PCR. Solexa libraries were prepared according to the manufacturer's recommendations. Library quality was assessed on a 2100 Bioanalyzer system (Agilent). All samples were single-end sequenced with 36-bp reads using an Illumina Genome Analyzer IIX by the EMBL Genomics Core Facility.
