Cryopreservation of Microbial Stocks: Used to prepare glycerol stocks for long-term storage of bacteria such as Escherichia coli; 50% Glycerol Solution is diluted to a 15–25% final concentration.

Sample Loading for Electrophoresis: Added to DNA, RNA, or protein samples to increase density and prevent diffusion during gel loading.

Enzyme and Protein Stabilization: Included in storage and assay buffers to stabilize enzymes and proteins during freezing, thawing, and transport.

Competent Cell Storage: Serves as a cryoprotectant for freezing chemically or electrocompetent bacterial cells.

Glycerol Density Gradients: Used to prepare glycerol gradients for fractionation of proteins and nucleic acids via ultracentrifugation.

PCR Additive: At low final percentages, improves amplification by stabilizing DNA polymerases and aiding difficult templates.
