Published Data on Aquatic Genomics

Peer-reviewed research has established a full toolkit of insertion and deletion detection methods for aquatic model organisms such as zebrafish. These technologies span from labor-intensive gel-based assays to automated high-throughput platforms including fluorescent PCR, HRMA, sequencing and qPCR.

Proper assay design requires avoidance of SNPs within amplicons, especially for heteroduplex-based methods. These nuclease-independent workflows are compatible with various mutant generation systems and broadly applicable across model systems. Drawing on these validated methods, BioVenic delivers optimized indel detection pipelines tailored to diverse aquatic species.
