title: The gut microbiome of wide-type and as3mt mutants under different arsenic exposure in zebrafish
design: The DNA samples were subjected to PCR amplification with primers 515F (5-GTG CCA GCM GCC GCG GTA A-3) and 907R (5- CCG TCA ATT CMT TTR AGT TT-3) targeting the V4-V5 hypervariable region of the 16S rRNA gene.
