Guide to Free qPCR and RT-qPCR Master Mix Samples

Free qPCR samples contain enough reagents for up to 200 rxns (20 µL). These samples suit routine testing and research with options for probe or SYBR Green assays. Selection depends on assay type, starting material, and thermocycler.

Steps to Select Your Sample

First, pick the right sample based on your needs. Then, choose the sample size on the product page. Finally, add it to your cart.

Consider assay type such as probes or SYBR Green. Factor in starting material like DNA or RNA. Match your qPCR thermocycler for best results.

Probe Assay Options

Probe assays provide highly specific detection and allow multiple targets in co-detection. They adapt well to routine testing with versatile methods.

SYBR Green assays offer a cost-efficient choice for single target detection. They use simple assay design and rely on melt curve for specificity. These suit research purposes.
