Invitrogen 50 bp DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA fragments ranging from 50 bp to 2,500 bp. The 50 bp DNA ladder consists of 17 chromatographically purified individual DNA fragments with reference bands of 2500, 800 and 350 bp for easy orientation.

The 50 bp DNA ladder is ideal for DNA fragment separation on 2% agarose gels.

50 bp DNA Ladder Features:
•Distinctive, clear bands—Chromatographically purified fragments provide consistent and reliable results
• Convenient—Pre-mixed 6X TrackIt Cyan/Orange loading buffer makes it easy to track sample DNA migration
• Accurate—Gets the exact amount of DNA in each band

Product Usage
Double-stranded DNA molecular weight standards can be observed on 2% agarose gel after ethidium bromide or SYBR Safe staining. This molecular weight standard is designed with DNA bands of uniform intensity, making it easy to see each band clearly. The exact amount of DNA in each band allows for approximate quantification of sample DNA.

This molecular weight standard can be radiolabeled using T4 polynucleotide kinase or T4 DNA polymerase.
