Is Beijing Nuosai Gene Direct Selling?

I haven't heard of it. There are many gene decoding entries in Xue Jiajin's gene, and the sample analysis method adopted is highly fault-tolerant. In addition, the high-fidelity amplification technology of trace genes can be used to obtain enough genetic information from the trace samples of oral exfoliated cells. Of course, it can also use conventional biological samples such as anticoagulant venous blood and tissue samples to obtain DNA sequences. Anticoagulant venous blood, saliva and exfoliated cells of oral mucosa were used as gene detection samples.
