Resuspend in one/twentieth the volume of new maintenance broth, and incorporate an equivalent volume of twenty% (v/v in water) sterile glycerol. Cells developed on agar could possibly be scraped from the area in to the ten% glycerol broth. Dispense modest aliquots with the suspension into sterile vials. Retail store the vials in liquid nitrogen or in the mechanical freezer at no more than 50
Get clean up dried conical flask According to the prerequisite of media. Weigh and suspend the quantity on the dehydrated media According to volume needed, as per company’s instruction.
