Dna ladder

Manufactured by Solarbio
Sourced in China

A DNA ladder is a molecular weight standard used to determine the size of DNA fragments in gel electrophoresis. It consists of a mixture of DNA fragments of known sizes, which are used as a reference to estimate the size of unknown DNA samples.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
