The RTSF Genomics Core at Michigan State University offers a number of options for genotyping services. The available platforms and technologies encompass a wide range of sample and assay set sizes allowing analysis of a handful to millions of loci simultaneously.

GeneScan/Fragment Analysis Services

Amplified Fragment Length Polymorphism (AFLP)

AFLP is a powerful DNA fingerprinting technique that can be used for plants and bacteria based on the selective amplification of restriction fragments from a total digest of genomic DNA.

Short Tandem Repeats (STR)

STR analysis is an important complement to both the length and sequence-based DNA typing systems used for human identification. Due to their small size STRs are often used successfully to analyze samples containing minute amounts and degraded DNA that cannot be typed using conventional methods. STRs are commonly used for forensic applications determining population genotype frequencies.

Recommended DNA quantity for GeneScan/Fragment Analysis: 200-300 ng of DNA in a 20 µL volume.  DNA must be quantified by fluorometric method, such as Qubit or PicoGreen.

TaqMan probe based Genotyping

TaqMan® 5'-nuclease assay chemistry provides a fast and simple way to get single nucleotide polymorphism (SNP) genotyping results. Each TaqMan® SNP Genotyping Assay includes two allele-specific TaqMan® MGB probes containing distinct fluorescent dyes and a PCR primer pair to detect specific SNP targets.  Assays are run in a 384-well format on our QuantStudio 7 Flex qPCR instrument.
