qPCR Probes
Quantitative PCR (qPCR), also known as real-time PCR, is an essential tool in fundamental research and clinical diagnostics. It plays a vital role in detecting infectious diseases, cancer biomarkers, genetic disorders and other targets.
BiOligo provides customized qPCR probes, including TaqMan probes, molecular beacon probes and super-quenched probes, all tailored to meet your specific research needs.
Probe Design
The selections of fluorophores and quenchers are essential to probe design:
- An appropriate fluorophore choice is related to the qPCR instrument used;
- An appropriate quencher choice is related to the quenching mechanism involved.
