             In addition to our protocol guide, Natronaut has created an easily accessable codon optimization table specifically for <i>Vibrio natriegens</i> that can be directly used in Snapgene. This table will assist researchers in selecting the most efficient codons for gene expression, optimizing the performance of genetic constructs, and improving experimental outcomes for future teams working with <i>Vibrio natriegens</i>
