Bio rad molecular rulers are dna standards with precisely defined size intervals between bands dna ladders for simplified estimation of the length of nucleic acids separated on agarose gels.
We recommend loading 0 5 1 0 µg of 50 bp dna ladder diluted in sample buffer.
Or 0 5 2 5 µl for silver staining up to 1 000 applications.
For long term storage store at 20 c.
