Agilent feature extraction software v9.1.3

Here, we performed array-based comparative genomic hybridization to demonstrate that there was no chromosome aberration after the CRISPR/Cas9-mediated genome-editing intervention. The genomic DNA of iPSCs with a low passage number (4th–7th passage) was isolated and intermittently sonicated using a Digital Sonifier 450 sonicator probe (Branson Ultrasonics, Danbury, CT, USA). DNA samples were amplified using the GenomePlex WGA kit (Thermo Fisher Scientific, Waltham, MA, USA). A Genomic DNA ULS Labeling Kit (Agilent) was used to label the amplified DNA with either Cy3 or Cy5. As recommended by Agilent, 2.0–2.5 g of amplified DNA were used as the input starting material for each labeling reaction. Scanning and image analysis were conducted according to the Agilent Oligonucleotide Array-based CGH for Genomic DNA Analysis Protocol (version 4.0). Microarrays were scanned using an Agilent G2565BA DNA Microarray Scanner (Agilent). Agilent Feature Extraction software (v9.1.3) was used to extract data from raw microarray image files. Agilent CGH Analytics software (v3.4) was used to visualize, detect, and analyze the aberration patterns from CGH microarray profiles.
