Answer:It contains reference fragments from 100 bp to 2.5 kb.
Answer:The marker is supplied as 50 µL.
Answer:The DNA size marker concentration is 100 ng/µL.
QX DNA Size Marker 100 bp–2.5 kb is a reference ladder for QIAxcel DNA fragment sizing. The 50 µL reagent contains defined DNA fragments of 100, 200, 300, 400, 500, 600, 700, 800, 1000, 1200, 1500, 2000, and 2500 bp at a nominal concentration of 100 ng/µL. These reference peaks are used by QIAxcel analysis software to establish a size-calibration curve for unknown DNA fragments within the supported range. The marker is useful for PCR-product analysis, restriction digests, cloning checks, and other applications where fragment size must be estimated from automated capillary electrophoresis. It should be paired with the appropriate alignment marker and QIAxcel process profile for the selected gel cartridge. Correct marker assignment is important because sizing accuracy depends on matching the analysis settings to the actual reference ladder.
