50bp marker

Bio&SELL 50bp DNA marker:
  • 10 bands: 50 bp to 700 bp


  • Exact sizing


  • Relative quantification


  • 300 bp band for easy size recognition with enhanced intensity


1 μg Bio&SELL 50 bp DNA marker on a 1.0% agarose gel.

Separation at 5 V/cm for 3.5 hours.


The DNA marker is available in 3 variants:

1. Marker “without loading dye”: only the marker is included. For loading your gel you have to add a loading buffer to the marker. Bio&SELL offers two loading buffers with either the dye Orange G or bromophenol blue.

2. Marker „ separate loading dye“: we supply 6-fold concentrated loading buffer along with the DNA markers. Here you can choose between the dye Orange G or bromophenol blue.

For best results, we recommend mixing your test samples as well with the Orange G (or bromophenol blue) loading buffer. The quantity is sufficient for up to 2000 of your samples (250 μg marker). Thus you benefit from the advantages of the Orange G dye and save an additional loading buffer.

3. Marker „ready-to-load“: this marker is prestained, it already contains the loading buffer with bromophenol blue in an optimal concentration. For a quick and easy loading of your agarose gel: „simply load and run“.
