X. Lemercinier et C. Jones, An NMR spectroscopic identity test for the control of the capsular polysaccharide from Haemophilus influenzae type b, BIOLOGICALS, 28(3), 2000, pp. 175-183
We describe the use of Nuclear Magnetic Resonance (NMR) spectroscopy to con
trol the identity of purified bulk capsular polysaccharide [called poly(rib
osylribitolphosphate) or PRP] from Haemophilus influenzae type b (Hib), and
derivatised forms, used in the production of Hib polysaccharide-protein co
njugate vaccines. We describe the approaches we have developed to validate
this teal. (C) 2000 The International Association for Biologicals.
