WebOct 17, 2024 · Real-time detection of PCR products can be achieved through the use of either: 1) DNA-binding dyes or 2) fluorescent PCR primer- and probe-based chemistries. As their name implies, DNA-binding dyes are non-specific fluorescent dyes that intercalate with any double-stranded DNA (dsDNA) molecules. WebFluorophores (or fluorochromes) are commonly used in conjugation with antibodies as detection reagents in applications such as flow cytometry. Fluorophores can absorb and emit light within a range of wavelengths, normally referred to as the absorbance (excitation) and emission spectra.

WebWe are proud to offer a complete multiplex qPCR solution that enables you to perform up to a 4-plex reaction for gene expression and a duplex reaction for genotyping analysis. WebOct 21, 2024 · Fluorophores are molecules that can absorb light energy in a process called excitation and re-emit light energy at a longer wavelength in a process called … shoulder and upper arm muscles

WebTwo primers are used for fragment analysis: one to bind to the 5¢ end of the template gene and a second to bind to the 3¢ end. One of the primers is labeled with a fluorescent molecule (i.e., a fluorophore) at the 5¢ end. If multiplexing, primers with the same fluorophore should not be used that produce fragments of a similar length. WebCalibrate the Real-Time PCR Instrument for Dyes and Fluorophores Prior to starting a qPCR experiment, verify that the real-time PCR instrument is compatible and calibrated correctly for the dyes and fluorophores chosen. CFX Manager™ software has a Dye Calibration Wizard with an easy guide to calibration (Tools > Dye Calibration Wizard). WebThe Cy5 fluorophore is also the basis for the lipophilic neuronal and long-term DiD cell tracing reagents, which append alkyl tails (≥12 carbons) onto the core fluorophore. For stable signal generation, Alexa Fluor 647 dye is generally brighter than Cy5 dye in protein and nucleic acid conjugates. shoulder and upper arm muscle pain
