MD108-50bp DNA Ladder

Cat. no. 4992796/4992797
Storage: -30~-15°C for 2 years. For frequently use, it can
be stored at 2-8°C for 3 months.
Concentration: About 0.08 mg DNA/ml

Description
The ladder consists of nine double-stranded DNA bands that are suitable as molecular weight standards for agarose gel electrophoresis.
The product is ready-to-use; it is premixed with 1×Loading Buffer for direct loading 3~6 μl on agarose gel electrophoresis.
The ladder is composed of nine individual DNA fragments(in base pairs): 500, 400, 350, 300, 250, 200, 150, 100,and 50. It contains one intense band (300 bp) for easy orientation. To load 6 μl of the product will provide 50 ng per DNA fragment with one intense fragment of 100 ng.

Buffer Contents
10 mM Tris-HCl (pH 8.4)
10 mM EDTA
0.02% Bromophenol Blue
5% Glycerol

Protocol

1. Directly load 3~6 μl of this product on the agarose gel(load 1 μl per 1 mm gel lane. The loading volume can be increased appropriately for wide lanes).
2. Electrophoresis condition: 2~3% agarose gel, 4~10 v/cm voltage.
3. DNA marker can be visualized using ethidium bromide under UV light.

Recommendations

1. Directly use, do not heat before loading.
2. Please use new agarose gel and change electrophoresis buffer in time, so as not to affect the electrophoresis results.
