VANGENES BIOTECH  GROUP

History and Mission

Vangenes Biotech Group, established in 2013, is an international biotechnology company headquartered in Xiamen City, China, with branches in the United States, Brazil and Chinese Hong Kong. We have NGS laboratories in China and the United States. We are committed to non-invasive pan-cancer early screening, non-invasive prenatal paternity testing, personal genome. We have rich scientific research experience, advanced technology platform and excellent expert team.

We have successfully applied the NGS technology and bioinformatics analysis technology to the field of genetic testing. We have non-invasive multi-cancer early screening technology (3 cancer types: lung cancer, liver cancer, breast cancer), non-invasive prenatal paternity testing technology, non-invasive Down's screening technology.

Our Service in Asia Pacific

Vangenes Non-invasive Prenatal Paternity Test

To safely and privately determine who is the father of your fetus at 7 weeks of your pregnancy, only need 10ml venous blood of pregnant woman and male samples like blood, nails, hairs etc.

Our Intellectual Patents

 

Through comparing and correcting the gene sequence obtained by processing the human genome using high-throughput sequencing technology, this method performs a T test between chromosomes to determine whether there is euploid variation in the chromosome in the mixed sample.

 

This patent well solves the technical problem of GC bias caused by high-throughput sequencing, thus making it possible to apply high-throughput sequencing in the detection of chromosome copy number variation in mixed samples.



The invention discloses a quantitative method for free fetal DNA (deoxyribonucleic acid) proportion in maternal peripheral blood. DNA containing designed SNP (single nucleotide polymorphism) in plasma is extracted by the aid of a designed primer and loaded on a machine after a series of treatment, sequencing products are compared to a human genome sequence, and a basic group of each SNP site is determined. The concentration of the free fetal DNA is quantified by analyzing the proportion of the basic groups in the SNP. Induced errors can be corrected by the aid of a plurality of SNP sites, the SNP sites are simultaneously calculated by a statistics method, and calculated free fetal DNA concentration accuracy is improved.


 

The invention provides a method for judging antenatal parental right relation with SNP. The SNP is used as a genetic marker, and judgment of the antenatal parental right relation is conducted through cooperation of the SNP and the high throughput sequencing technology. Only 10 ml of maternal peripheral blood is needed, free DNA extracted from the maternal peripheral blood plasma contains the free DNA of a fetus already, so that only one sample of a mother and the fetus is needed. Due to the fact that only the venous blood of a pregnant woman needs to be extracted, operation is simple and convenient, the pregnant woman and the fetus cannot be damaged.
