We recently reported the cloning and sequencing of the gene encoding a 31-kDa Treponema pallidum subsp. pallidum rare outer membrane porin protein, designated Tromp1 (D. R. Blanco, C. I. Champion, M. M. Exner, H. Erdjument-Bromage, R. E. W. Hancock, P. Tempst, J. N. Miller, and M. A. Lovett, J. Bacteriol. 177:3556-3562, 1995). Here, we report the stable expression of recombinant Tromp1 (rTromp1...

The outer layer of the vitelline membrane from hen egg yolk consists of ovomucin, vitelline membrane outer layer protein I (VMOI) and lysozyme. Here we report the occurrence of a further basic protein (pI 11.5) in the outer layer, which was designated as vitelline membrane outer layer protein II (VMOII). It was dissociated from the outer layer in a 10% (w/v) NaCl solution and purified to homoge...

background: leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic leptospira spp. a major challenge of this disease is the application of a basic research to improve diagnostic method. outer membrane proteins of leptospira are potential candidates that could be useful in diagnosis. among them the lipl41 is an immunogenic protein which is present on...

different strains of escherichia coli (e. coli) from human, chickens, and the common strain between human and chickens were isolated and typed with mono-specific antibody. the e. coli strains from each group of human, chicken and common between human and chicken were selected. the polypeptide patterns of selected strains were analyzed and compared with each other by sodium dodecyle sulphate pol...
