The P2 porin protein is the most abundant outer membrane protein (OMP) of nontypeable Haemophilus influenzae (NTHI) and shows extensive antigenic heterogeneity among strains. To study the molecular basis of this heterogeneity, the DNA sequences of th

Summary Outer membrane protein P6 is an important antigen expressed on the surface of all strains of Haemophilus influenzae. The predicted amino acid sequence of P6 contains a region of alpha helices that shares sequence identity with a family of hel

Infections caused by Haemophilus influenzae are a major worldwide health problem. In particular, nontypeable strains of H. influenzae are a common cause of otitis media in infants and children. A vaccine to prevent these infections would result in th

Allyl vinyl ether can be polymerized to highly isotactic polymer with SbCl5 in toluene at ca. −10°C. The stereospecificity is not significantly lower than that of polymer made at ca. −75°C; The reproducibility of the process is greatly improved
