Cupidpeptides

Cupid Peptides was a biotechnology company based in Cardiff, Wales, specializing in the development of a proprietary cell-penetrating peptide (CPP) platform. The company's core Cupid technology utilized a unique 14-amino acid sequence to facilitate the direct translocation of proteins and peptides across the plasma membrane into living cells. This method offered a non-toxic and efficient alternative to traditional delivery techniques like microinjection or electroporation, maintaining the biological activity of the cargo. Cupid Peptides primarily commercialized this technology through a range of research reagents, including cell-permeable fluorescent proteins and enzymes. Although the platform held promise for therapeutic applications in intracellular drug delivery, the company ceased operations and was dissolved in 2022.
