CRISPR-Cas9 genetic editing mechanisms require a short (typically 20nt) RNA sequence complementary to a target site next to a Protospacer Adjacent Motif (PAM) sequence. The most commonly used Cas9 nuclease (SpCas9) from Streptococcus pyogenes recognizes the PAM sequence NGG. One new function introduced a few years ago will search for PAM sequences in your sequence. […]
If you are using CRISPR editing techniques then there are two useful functions in MacVector for you: MacVector will scan Nucleic Acid sequences for Protospacer Adjacent Motifs (PAM) associated with the CRISPR Cas9 and related enzymes cleavage and modification functions. MacVector’s Analyze | Align To Reference… tool is ideal for screening reads for the short […]
MacVector’s Analyze | Align To Reference… tool is ideal for screening reads for the short insertions, deletions or substitutions resulting from CRISPR experiments. Simply open your reference sequence, choose Analyze | Align To Reference…, click on the Add Seqs toolbar button to add reads from different clones/experiments, then click on Align to align the reads […]
If you are screening a set of clones for the presence of changes after a CRISPR experiment, then the MacVector Analyze | Align To Reference functionality is the approach to use. However, you may find that the default parameters are not ideal for this type of analysis – they are tuned for simple sequence confirmation […]
The Database | Align To Folder function is an extremely useful tool to help you find matching sequences on your own local file system. It is essentially a BLAST search of your own private sequence collection – a little slower, but more sensitive. You can use it to easily open all of the sequences you […]
