An uncharged polysaccharide purified from agar. Agarose melts when heated to 100 C and resolidifies when cooled below about 50°C. When it solidifies agarose forms a matrix. The size of the pores in the gel matrix can be varied by using different concentrations of agarose: the higher the concentration of agarose, the smaller the pore size.
A polysaccharide obtained from agar that is the most widely used medium for gel electrophoresis procedures.
A gel-like substance added to a DNA sample for separation of the DNA from the proteins in a process called electrophoresis.
Is a product obtained from a seaweed (mostly red algae), that when mixed with water and boiled becomes gel-like and solidifies after cooling.
One of the constituents of agar. Often used in preference to agar because it gels at a lower temperature and does not contain the inhibitors of virus growth frequently present in agar. It is also used widely in gel electrophoresis because it has a more uniform pore size than that of agar. ( 10)
A polymer that is used as a matrix for electrophoresis.
