Despite the successful method of using organic solvents, such as glycerol, to prevent cryo-damage when freezing proteins for storage and distribution, there are still several disadvantages associated with it, including sample viscosity, interference with colorimetric assays, influence in protein interactions, or issues pertaining to cytotoxicity.

With its unique technology, Leadgene offers products in glycerol-free formulations, which retains biomolecules with their natural features and activities.


Notably, these products are compatible with LEADSPHERE® Lyophilization Technology and are ideal for developing point-of-care testing.
