MapMarker® are sets of high quality fluorescently labelled DNA fragments designed to provide consistent intensities and migration patterns for DNA sizing standards and are compatible with all fluorescent-based separation instruments systems including capillary electrophoresis. MapMarker DNA fragments are uniformly spaced to provide accurate base calling and precision sizing of samples.
MapMarker® contains singular DNA strands with a single fluorophore and bands ranging from 50 to 1000 base pairs. Only single strands are labeled with a single dye; the products are available with all of the most commonly used fluorescent dyes, including rhodamine, tetramethylrhodamine, x-rhodamine and fluorescein. Custom configurations and dyes are also available.
MapMarker® are evaluated for resolution, intensity and background on denaturing polyacrylamide sequencing gels using laser excitation. MapMarkers® are free of extraneous peaks over their entire sizing range and are free of "pull up" signal in other channels. MapMarkers® produce consistent within run and between run sizing within their size range and reproducible runs in gels or capillary-based systems. MapMarkers may be used under either denaturing or nondenaturing conditions.
The markers are fully compatible with all current methodology, equipment and software. It can be used as well on gels as on capillary-based systems. All MapMarkers are at 8 fmoles/band/µl.
