Nucleic Acid Molecular Weight Markers
Alkali Scientific DNA Markers (Low Range) 250 bp Ladder, 1 Milliliter
DNA Markers (Low Range) 250 bp Ladder (1 mL) is a liquid format DNA marker used in gel electrophoresis for the molecular weight determination of DNA fragments. The 250 bp ladder contains a series of DNA fragments that are useful for estimating the size of unknown DNA samples. This marker is commonly used in molecular biology labs to confirm the integrity of DNA samples, analyze restriction enzyme digestions, and ensure accurate molecular size estimation during electrophoresis. The 250 bp ladder is ideal for low-range applications, making it a standard choice for small DNA fragment analysis and various molecular research experiments.

STEMCELL Technologies DNA Loading Dye, Size: 3 mL
DNA Loading Dye is a ready-to-use marker dye containing orange G (0.4%), bromophenol blue (0.03%), and xylene cyanol FF (0.03%), in 15% Ficoll 400, 10 mM Tris-HCl (pH 7.5), and 50 mM EDTA (pH 8.0). The dye is used for loading DNA samples into agarose gel wells and tracking migration during electrophoresis. In a 0.5 - 1.4% agarose gel in 0.5X TBE, xylene cyanol FF migrates at approximately 4 kb, bromophenol blue at approximately 300 bp, and orange G at approximately 50 bp. This product is free of nuclease activity.
