Popis

General description

Noble agar, also known as agar or agar-agar, is a gelling hydrocolloid extracted from sea weeds such as Gelidium and Gracilaria. It′s structure contains repeating units of D-galactose and 3,6-anhydro-L-galactose, with a few differences, in addition to a low ester sulphate residue. Agarose and agaropectin are the key components of agar. Noble agar is majorly used as both human and animal food supplement. In addition, it is also used in industries for the preparation of solid microbiological media.

Select agar is majorly used as a component of culture media for molecular genetics related studies.

Application

For use as a component of culture media for molecular genetics.

Select agar has been used as a gelling agent to prepare dielectric phantoms along with polyvinylpyrrolidone (PVP) and salts. It has also been used as a component of LB agar for the bacterial transformation screening.

Select agar has been used in the preparation of Luria Bertani (LB) agar plates during DNA transformation process.
