Figure Lengend Snippet: Characterization of CRISPR–SaCas9 target site mutations in HIV breakthrough cultures. Supernatants from cultures exhibiting syncytia formation were collected at the peak of infection and used to infect fresh cells transduced with SaCas9/gRNA. After robust viral replication, cells were harvested, and total cellular DNA was extracted. The target region was amplified by PCR and analyzed by Sanger sequencing. Sequences were aligned to the LAI reference, with the wild-type sequence shown at the top and culture numbers indicated on the left. The target sequence is underlined, and the PAM sequence is highlighted in blue. Nucleotide substitutions are shown in red, predicted SaCas9 cleavage sites are indicated with black triangles, and corresponding amino acids are displayed on the right.
Article Snippet: gRNA spacers were designed using Benchling CRISPR guide design software ( https://www.benchling.com/ ), targeting the HIV-1 DNA genome of the primary LAI virus isolate.
