16S Metagenomics-Direct Primer Pool & DNA Library Kit for Illumina – YST0123 COMBO is an Illumina compatible NGS Library Kit that uses a novel Two-Step PCR method for bacterial DNA library preparation kit for the Illumina high-throughput sequencing platforms. We have revolutionized the 16S library preparation process and eliminated the tedious DNA extraction step. With this kit you can directly amplify crude samples, such as stool, soil, sewage, etc., to make 16S DNA libraries for NGS.
