Molecular Biology Grade Agarose
This is the high purity gelling agent needed for
gel electrophoresis experiments.
Each tiny one inch square packet contains between
600 and 700 milligrams of agarose, enough to make 50 to
100 milliliters of gel, depending on the gel strength
you choose to make.
For large DNA fragments, a weak gel is needed, so most
experimenters will be using one packet in 100 milliliters
of distilled water.
Dissolves easily in cold water. Microwave 100 milliliters
for 30 seconds to make the gel.
