immune responses to some proteins and synthetic polypeptides in inbred strains of rats.the antibody responses to dnp-bovine gamma globulin, bovine gamma globulin, human serum albumin, ovalbumin, pepsin and five synthetic polypeptides were examined in strains of inbred rats representative of eight common major histocompatibility complex (rti) haplotypes. with each antigen the antibody response varied considerably among strains, and the data provide many potential strain and antigen combinations with which to study the genetic control of the immune response.197991650

[antigenic structure of the l forms of br. abortus 544].the gel precipitation test after ouchterlony and mancini was employed to study comparatively the antigenic structures of s and l forms of brucella abortus 544. reduction of the antigenic fractions was established with the l-transformed brucella organisms as compared to the initial cultures. reduced were mainly fractions of the antigenic structures that took part in cell wall building. cytoplasmic antigens remained unchanged. those that participated in the building of cell walls precipitated in c ...197992852
relatedness among coagulase-negative staphylococci: deoxyribonucleic acid reassociation and comparative immunological studies.dna-dna-homology values were determined under restrictive to relaxed reassociation conditions with type strains and some additional strains of coagulase-negative staphylococci belonging to ten different species. the immunological relationship of the catalases present in the type strains of these species was also determined by applying double immunodiffusion and microcomplement fixation. the results of these studies support the previous proposal to subdivide the coagulase-negative staphylococci i ...197992972
immunological properties of peptic fragments of bovine serum albumin.the effect of peptic degradation on the immunological and antigenic properties of bovine serum albumin (bsa) was investigated. molecular fragments obtained after various times of digestion (3-360 min) were studied. enzymatic digestion resulted in a rapid loss of serologically defined antigenic determinants. the immunogenicity of the fragments as measured by the level of reaginic and total anti-bsa antibody response in bdf1 mice was also diminished. pre-treatment of mice with fragments exhibiting ...197993079

site-specific endonucleolytic cleavages and the regulation of stability of e. coli ompa mrna.the stability of ompa mrna is growth-rate dependent. we show that the 5' noncoding region of this mrna provides a target for site-specific endonucleases. the rate of degradation of ompa mrna parallels the rate of these endonucleolytic cleavages, implying that endonucleolytic rather than exonucleolytic attack is the initial step in ompa mrna degradation. thus the 5' noncoding region appears to be a determinant of mrna stability, and endonucleolytic cleavages in the 5' noncoding region may well re ...19883280138
