Agar, microbiology tested, for cell culture (powder) [9002-18-0]

Agar, microbiology tested, for cell culture (powder) is a jelly like substance that contains agarose and agar gel. Agar, microbiology tested, for cell culture (powder) can be isolated from the cell walls of red algae species such as Gelidium and Gracilaria (Ogonori). The gelation and melting of Agar, microbiology tested, for cell culture (powder) is based on the hydrogen bridge (physical gels), so the gelation is reversible. Agar, microbiology tested, for cell culture (powder) is widely used in food additives, plant tissue culture, microorganisms culture media, fingerprint recognition, and medical fields^[1][2].

Preparation of agar beads loaded with sulphamethizole^[3]
(1) 1.5 g agar dissolved in 20 mL water, heated until completely dissolved, and then cooled to about 70°C.
(2) 2 g sulphamethizole was added to (1) medium suspension, and the mixed drops were added to a 100 mL graduated cylinder containing Burgess's reagent using a 3 mL plastic syringe (the cylinder was immersed in ice water).
(3) After filtration, beads were dried under vacuum at room temperature (20°C) for 24 h.
