Cupid Peptides

Cupid Peptides is a Cardiff-based manufacturer of cell-penetrating peptide products for biomedical research.

Its proprietary Cupid sequence, derived from the amoeba Dictyostelium discoideum, enables large recombinant protein cargoes to traverse cell membranes and access intracellular targets.

Products offer the specificity of dominant-negative or siRNA approaches with the speed of small molecule inhibitors.

Custom synthesis services are available for researchers requiring bespoke cell-permeable fusions of their chosen protein cargo.
