Home / About Us

53Biologics is a fast-growing global CDMO based in Valladolid (Spain) with extensive experience in decoding biologics overexpression, from DNA to proteins.

Why 53Biologics?

DNA is 'read' in a specific way, like letters and words are read to from left to right to reproduce a message, the encoded information is translated in one direction. This reading frame, from the five-prime end (5’) to the three-prima end (3’) is in the genesis and the sense of life for 53Biologics. The initial designations refer to the number of carbon atom in a deoxyribose molecule to which a phosphate group bonds. But for 53Biologics is the way to translate, from a DNA to a protein, from just encoded information to a reality.
