摘要: The present invention provides a novel method for the identification and clonal isolation of antibodies that bind to unique epitopes. The method is based on the use of antibodies as solid phase capture reagents to bind a known capture antibody epitope, thereby precluding the capture antibody epitope from being presented to a population of antibodies to be screened. The method is particularly suited for screening libraries of cloned antibodies, such as phage display combinatorial antibodies. An antibody specific for herpes simplex virus (HSV), was employed as a model for the assay.

摘要: Antibodies are disclosed which specifically bind to native PrPSc in situ. Preferred antibodies bind only to the native PrPSc of a particular species e.g., human, cow, sheep, pig, etc. Particularly preferred antibodies bind specifically to a particular isoform of human PrPSc. Preferred antibodies of the invention are (1) produced by phage display methodology, (2) bind specifically to native PrPSc, (3) neutralizes the infectivity of prions, (4) bind to PrPSc in situ and (5) bind 50% or more of PrPSc in a liquid flowable sample. Antibodies of the invention can be bound to a substrate and used to assay a sample (which has any PrPc denatured via proteinase K) for the presence of PrPSc of a specific species which PrPSc is associated with disease. Antibodies which specifically bind to human PrPSc can be labeled and injected carrying out an in vivo diagnostic test to determine if the human is infected with prions associated with disease. The antibodies are preferably produced using phage display technology wherein the genetic material in the phage expressing the antibody is obtained from a mammal with an ablated endogenous PrP protein gene and an endogenous chimeric PrP gene which mammal had been inoculated with PrPSc to induce antibody production.
