Which Agar do I want?
A0930 Agar, Bacteriological
Bacteriological agar is a highly purified extract of select Gelidium marine algae, forming part of the cell wall, that gives excellent growth characteristics used in a wide variety of microbiological applications. Agar is a phycocolloid, a complex mixture of several sugar compounds that retains a gelatinous structure at RT after boiling. Bacteriological agar is purified by successive washings to remove or extensively reduce chemical contaminants, color and salts. After autoclaving, agar is light amber and free of particulates, solidifying into a clear, firm gel.
Bacteriological Agar is suitable for all molecular biology applications (i.e. bacterial and phage growth, M13 and Lambda). It is superior to standard microbiology grade agars.
A0940 Agar, Drosophila
Gelidium based Drosophila agar is an inexpensive growth medium especially suited to the growth and nutrient requirements of Drosophila without the expense of bacteriological grades. This is a food grade agar which offers excellent clarity.
A0950 Agar, Noble
Noble Agar is the highest purity agar available. It is washed in accordance with the Noble and Tonney method which removes trace impurities, ash and minerals that interfere with many sensitive applications, such as electrophoresis and immunological procedures.
