Lyophilization Reagent (2X Concentrate) 500 ml This clear solution is designed to simplify protein lyophilization. It is composed of a mixture of a matrix (caking agent) and lyoprotectant, that when mixed act synergistically to provide a solution with a high eutectic point, solid matrix, and excellent protein stability. It is prepared as a 2X concentrate that can be used as is, or mixed in equal concentration with a sample. Mixing the 2X Concentrate with buffers may require a reassessment of freeze drying parameters. Lyophilization Reagent is sterile filtered and bottled aseptically. It is provided in 500 ml PET bottles.
