SERVICES
haplotyping by single-chromosome sequencing
4DGenome is leading technology company, providing microbiome, single cell, single chromosome, low input whole genome sequencing service. We also offer customized bioinformatics service. Let us provide you with the personalized service you deserve.
WHOLE GENOME SEQUENCING
Low input of DNA or RNA
Whole Genome Sequencing (WGS) provides the most comprehensive map of an organism's genetic information. High quality sequencing is now available with as little as 1 ng of starting material.
SINGLE CHROMOSOME SEQUENCING
Human single chromosome isolation and sequencing
We provide the cutting-edge technology service for single chromosome sequencing. Our novel approach is chromosome range haplotyping determination.
SINGLE CELL SEQUENCING
single cell isolation and whole genome sequencing for DNA or RNA
Single cell sequencing (SCS) is becoming a new approach to study biological heterogeneity. We provide single cell isolation, whole genome amplification and sequencing service.
MICROBIOME SERVICES
16S ribosomal RNA sequencing
We offer 16S ribosomal RNA (rRNA) gene sequencing service and data analysis. Next-generation sequencing enables analysis of the entire microbial community within a sample.
CUSTOMIZED TARGET DESIGN
probe design for DNA capture
Targeted capture provides an efficient and sensitive means for sequencing specific genomic regions in a high-throughput manner. If you’re looking for customized design of your capture sequencing, we will meet your satisfaction.
BIOINFORMATICS SERVICE
High-throughput data analysis
We provide customized service for bioinformatics analysis, including NGS data analysis, haplotyping, imputation and ancestry analysis. We also provide service of software development.

SCIENCE&EDUCATION
1. WHAT IS A HAPLOTYPE?
The term haplotype was invented about 50 years ago by the Italian geneticist Ruggero Ceppellini (Milan, 1917 – 1988). Now the term and concept have been widely used since, long before DNA analysis. Human genomes are diploid. Human diploid cells contain two sets of homologous chromosomes, which have slightly different sequences from each other. Their complete description and interpretation require to know not only their mutations but also the arrangement of these mutations onto chromosomal haplotypes. A haplotype is a sequence (or a collection of mutation) of each of those two homologous chromosomes. A haplogroup is a group of similar haplotypes that share common ancestors.
2. WHY NEED CHROMOSOMAL HAPLOTYPES?
It is because two homologous chromosomes have different mutations, are functioning differently, their functionalities are closely related to their combinatorial content of mutations, and their functionalities are closely related to human diseases.
3. WHY NEED TO MEASURE THE HAPLOTYPES EXPERIMENTALLY?
It is because it is much more accurate with less switch errors on long-range or chromosomal-range of haplotyping.
4. WHO NEED HAPLOTYPES?
Disease-gene discovery
Rare diseases and rare mutations
long range eQTLs
Genetic epidemiological studies (association studies, linkage studies)
Functional interpretation of various high-throughput data sets
Linkage disequilibrium assessment
Genetic demography
HLA typing
Ancestry analysis
Evolution
Population history
Pharmaceutical companies
Hospitals
