Reporter Gene Assays

Unlike reporter gene assays, RT-qPCR can be used on native, non-transformed cell types, and RT-qPCR measures mRNA transcripts of the actual gene as it is expressed from within its natural environment, rather than transcripts from an artifial, plasmid-based consrtuct.*

LightCycler® 1536 Details

The LightCycler® 1536 optical unit facilitates mono- and dual-color assays using a variety of dyes, such as FAM, VIC, and Yellow 555, by supporting formats including Universal ProbeLibrary (UPL) probes, hydrolysis probes, and intercalating dyes (e.g., BrightGreen). The unique thermal block cycler design, in combination with the LightCycler® 1536 Multiwell Plate, enables very high well-to-well homogeneity and inter-assay reproducibility.

The LightCycler® 1536 Software supports the next generation of real-time PCR results (e.g., Cp's, endpoint fluorescence values), providing novel threshold functions for data refinement and powerful tools for data sorting and reviewing. Since this system is designed for automated high-throughput laboratory workflows, the instrument’s software allows easy data management for network and LIMS environments. In combination with Roche RealTime ready reagents, the system also features a new surveillance concept that checks for pipetting errors.
