Sample GSM1053218 Query DataSets for GSM1053218
Status Public on Dec 21, 2012
Title CENP-A ChIPSeq_JT15
Sample type SRA
 
Source name C.albicans strain J191, IP
Organism Candida albicans
Characteristics strain: J191
growth conditions: Log phase grown C. albicans cells
media: YPDU
protein: CENP-A/Cse4
chip antibody: Polyclonal anti-Cse4 antibodies (Sanyal K & Carbon J PNAS 99, 12969 - 12974 (2002))
Treatment protocol None
Growth protocol C. albicans cells were grown to log phase at 30oC
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and CENPA-DNA complexes were isolated with antibody.
Libraries for multiplex ChIP Sequencing were constructed using NEXTflex™ ChIP-Seq Sample Preparation Kitprotocol outlined in “Preparing Samples for ChIP Sequencing of DNA” (BIOO Scientific# IP-5143-01). Briefly, DNA was subjected to a series of enzymatic reactions that repair frayed ends and phosphorylate the fragments. The end repaired fragments were subjected to two rounds of SPRI clean up with Agencourt AMPURE XP beads (Beckman Coulter #A63881) for size selection of DNA inserts between 300 to 400bp. The size selected fragments were adenylated with a single nucleotide 3'dATP overhang (BIOO Scientific# IP-5143-01) and adaptors were ligated (NEXT Flex adapters). The fragments with ligated adapters were enriched with 18 cycles of PCR. The prepared libraries were quantified using Qubit and validated for quality by running an aliquot on a High Sensitivity Bioanalyzer Chip (Agilent). Libraries were sequenced on the Illumina Genome Analyzer IIx (GAIIx) following the manufacturer's protocols.
