Design Notes
To ensure binding specificity for the Cas13a variant from Leptotrichia buccalis, the stem region was adapted from Fozouni et al. (2020), which used the same stem region successfully when designing guide RNAs for the detection of SAR-CoV-2 RNA.
The recognition sequence was adapted from Barr et al. (2000), where a 34-bp region containing the ADHD-associated mutation of interest was selected. A length of 34 bp was chosen specifically in order to ensure that the overall guide RNA sequence would be 64 bp, which is the recommended length for CRISPR-Cas13a.
The sequence was then converted to DNA (converting all U bases to T) in order to be submitted to the Parts Registry.
