Genotyping mouse lines
Genotyping is critical to genetic research, allowing researchers to identify genetic variation and understand how changes in the genome influence biological processes, and the downstream impacts on overall health and disease progression. For researchers, accurate genotyping of mouse lines is essential for the success of their studies. At Ozgene, we offer comprehensive genotyping services tailored to meet the needs of various research projects.
What is genotyping?
Genotyping is the process of determining the genetic makeup of an organism by examining its DNA sequence. In mouse models, genotyping helps identify specific genetic variations that can influence phenotypic traits, disease susceptibility and response to treatments. Genotyping techniques have evolved significantly over the years improving accuracy, speed and the volume of data that can be generated from each sample. As animal models have become a cornerstone of genetic research, so has genotyping in supporting these studies.
Common methods of genotyping
Many methods can be employed to genotype mice, each with specific applications and advantages:
| Genotyping Method | Advantages | Limitations | Applications |
|---|---|---|---|
| Polymerase Chain Reaction (PCR) | High sensitivity and specificity, quick, cost-effective | Requires prior knowledge of the DNA sequence, contamination risk | Detection of specific genetic mutations, verification of cloned DNA sequences, pathogen detection |
| DNA Sequencing | Detailed nucleotide sequence information, detects all types of genetic variations | Expensive, time-consuming, complex data analysis | Comprehensive genetic analysis, identification of novel mutations, GWAS |
| Restriction Fragment Length Polymorphism (RFLP) | Reliable, reproducible | Labor-intensive, time-consuming, limited to variations affecting restriction sites | Genetic fingerprinting, disease marker identification, analyzing genetic diversity |
| Single Nucleotide Polymorphism (SNP) Genotyping | High-throughput, scalable | Requires knowledge of target SNPs, limited to known SNP variations | GWAS, pharmacogenomics, personalized medicine |
| Microsatellite Analysis (STR) | Highly polymorphic markers, useful for genetic linkage studies | Labor-intensive, expensive, prone to PCR artifacts | Forensic DNA profiling, population genetics, parentage testing |
| Amplified Fragment Length Polymorphism (AFLP) | High resolution, reproducibility, no prior sequence knowledge required | Technically demanding, high cost | Genetic mapping, assessing genetic diversity, identifying genetic markers |
| High-Resolution Melt Analysis (HRM) | Simple, rapid, high sensitivity for mutation detection | Limited to small amplicons, requires high-quality DNA | Mutation scanning, epigenetic studies, SNP genotyping |
| Denaturing High-Performance Liquid Chromatography (DHPLC) | High sensitivity for mutation detection, detects heterozygous mutations | Expensive equipment, limited to specific mutation types | Mutation detection, DNA fragment analysis, genetic screening |
| Mass Spectrometry-Based Genotyping | High accuracy, sensitivity, analyzes multiple samples simultaneously | High cost, complex instrumentation, specialized expertise required | SNP genotyping, detection of genetic modifications, quantitative allele frequency determination |
| Digital PCR | High precision and accuracy, quantifies absolute DNA amounts | Expensive, specialized equipment, limited throughout | Rare mutation detection, copy number variation analysis, pathogen quantification |
| Hybridization-Based Techniques | High specificity, detects multiple genetic variations | Requires high-quality probes, labor-intensive | Detection of specific DNA sequences, gene expression analysis, comparative genomic hybridization |
| Gene Chips and Microarrays | High-throughput, analyzes thousands of genetic variations simultaneously | Requires knowledge of target sequences, expensive | GWAS, gene expression profiling, pathway analysis |
| CRISPR/Cas-Based Genotyping | High specificity, efficiency, targets multiple genes simultaneously | Off-target effects, requires design and synthesis of guide RNA | Functional genomics, gene editing validation, mutation screening |
| Fluorescence In Situ Hybridization (FISH) | High resolution, visualizes genetic material in cells | Labor-intensive, requires high-quality probes and fluorescence microscopy | Chromosomal aberration detection, cancer diagnostics, gene mapping |
