We are your source for Poly-L-lysine, Poly-L-ornithine, Poly-L- arginine and other polyamino acids.
Polyamino acids have properties that mimic proteins, making them ideal for both drug delivery and the delivery of nucleic acids both in vitro and in vivo. These properties include increasing solubility and stability of drug attachments, drug encapsulation, drug targeting, bypassing multidrug resistance (MDR) factors, minimal stimulation of the immune system, low toxicity, and biodegradability. With over 20 years of experience in manufacturing polyamino acids we can supply both research and cGMP polyamino acids. Our process uses non-animal source materials, and we can manufacture custom polyamino acids for specific molecular weight ranges or polydispersity ranges (size distribution). Polyamino acids must be chemically modified for drug delivery use, we can conjugate polyamino acids to active pharmaceutical ingredients (API) for you. As the leading manufacturer of polyamino acids, we deliver the best quality and the largest selection.
