MapMarker®

The Next Generation in Single-Stranded Fluorescent DNA Sizing Standards

MapMarker® are sets of high quality fluorescently labeled DNA fragments designed to provide consistent intensities and migration patterns for DNA sizing standards and are compatible with all fluorescent-based separation instruments systems. 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, fluorescein and Radiant Dye 632 (orange channel). 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 non-denaturing conditions. MapMarkers® are stable for a minimum of 18 months when stored in the dark at 4°C.

MapMarker® are of excellent quality and very competitively priced. For large volume requirements or standing orders please contact us directly.
