Microsatellite Instability (MSI) Testing in Animal Tumor Samples
The detection of Microsatellite Instability (MSI) is a critical diagnostic tool used to assess genomic instability within tumor samples. This service focuses on the evaluation of MSI specifically from animal tumor samples, providing insights that are invaluable for understanding the genetic predispositions and potential therapeutic responses.
Microsatellites are short DNA sequences consisting of 2-5 base pairs repeated multiple times in a tandem arrangement. Mutations can occur within these sequences due to errors in replication or repair processes, leading to instability. MSI testing is particularly useful for identifying tumors with high mutation rates that may benefit from specific treatments.
In the context of animal tumor samples, this service ensures that the genetic makeup of tumors is accurately characterized. Understanding MSI helps researchers and clinicians tailor treatment plans based on the patient's (or in our case, the animal subject's) unique genetic profile. This can lead to more effective therapies with reduced side effects.
The testing process involves several steps including sample collection, DNA extraction, PCR amplification of microsatellite markers, followed by analysis using high-resolution melting curve analysis or next-generation sequencing techniques. These methods allow for precise quantification and categorization of MSI levels into different stages (MSI-High, MSI-Low, Microsatellite Stable).
Accurate MSI testing is essential not only for research purposes but also for ensuring compliance with regulatory standards such as those outlined in ISO 15189:2012. By providing reliable data on MSI status, our laboratory supports the development of personalized medicine approaches that enhance treatment efficacy.
The results from this service can have significant implications across various sectors including academia, pharmaceuticals, and veterinary sciences where understanding genetic variations plays a crucial role in advancing knowledge about disease progression and susceptibility.
