What is a random co-polyamino acid?
A random co-polyamino acid is a polymer made from two or more different amino acids that repeat in a random sequence.

Are the polyamino acid molecular weights average or absolute?
All polyamino acid molecular weights are average molecular weights and not absolute. Polydispersity is calculated from the ratio of Mw/Mn (Mw is the weight average molecular weight and Mn is the number average molecular weight).

What are some applications of polyamino acids?
Polyamino acids are used in a variety of applications.

    Clinical applications include:
  • Micro encapsulation
  • Nano and micro particles for tissue-targeted drug delivery and for the delivery of biologics
  • Vaccines for hepatitis C, multiple scleroses, emphysema
  • Gene therapy
  • Immuno suppressants

    Non-clinical applications include:
  • High throughput screening
  • Substrates for the purification of protein kinases
  • Cell adhesion
