title: GSM8974767: Bacterial metagenome A28; Homo sapiens; OTHER
library_construction_protocol: DNA was isolated by grinding, shaking, centrifugation, adsorption, elution with Mixed lysis buffer (buffer) containing Proteinase K, Isopropyl alcohol buffer solution, Ethanol buffer solution, ddH2O and so on. The V3/V4 regions of the bacteria were amplified using a pair of specific primers 341F/ 805R.
