Microbial Freeze Drying Buffer, Filter Sterilized, Color : Brown

Microbial Freeze Drying Buffer (Filter Sterilized) is a proprietary solution of hydrolyzed plant protein (a substitute for bovine serum albumin) and carbohydrate lyoprotectant meant for the long-term preservation of microorganisms, including both bacteria and fungi. This formulation evolved from Reagent 18, a proven solution for microbial freeze drying described in the ATCC lyophilization manual. Superior to traditional additives like sucrose and skim milk, Microbial Freeze Drying Buffer has a 90% viability of bacteria and is free of all animal products and proteins. This buffer maintains microorganisms’ viability through freezing, water removal, and subsequent storage of freeze dried microbial samples.

This freeze drying buffer is sterile filtered and aseptically packaged in 500 ml PET bottles. The shelf life is two years at room temperature with no loss of functionality if aseptic techniques are employed.
