Low-Range DNA Markers

 

Components:        

 

            Low-Range DNA Marker Solution: 0.4 ml (200 lanes); store at 4ºC

 

Product Description: The Low-Range DNA Marker set includes 8 linear DNA fragments (from 4.5 Kb to 0.1 Kb) ready for agarose or polyacrylamide gel analysis. The markers are supplied in a stabilized loading solution containing sucrose, bromophenol blue (lower dye), xylene cyanol (upper dye), and EDTA. These DNA fragments typically migrate as two easily recognizable quadruplets providing a convenient reference. The upper cluster includes 4 fragments of 4.5 Kb, 1.9 Kb, 1.2 Kb, and 0.8 Kb in sizes. The lower cluster also includes 4 fragments: 0.42 Kb, 0.29 Kb, 0.21 Kb, and 0.1 Kb. Each of the 8 DNA fragments carries 5’-overhangs and therefore can be conveniently radiolabeled by either Klenow (using labeled dATP) or Polynucleotide Kinase. An additional 60-bp fragment becomes visible when the marker set is overloaded or labeled with an isotope. The DNA markers set should be kept at 4ºC. The product is for research only.
