the objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51su. the four antigen preparations for immunization ofbalb/c mice were: cl: blv-flk cell lysate, uf: a fraction of cl (between 30 and 100 kda), wvp: wholevirus particles and sp: with ion exchange chromatography, gp51su was semipurified. a total of ninesucce...

In 2001, Canetti and Krawczyk proposed a security model (CKmodel) for authentication protocols. They also gave an indistinguishabilitybased definition for key exchange protocols. Since then the model has almost exclusively been used for analyzing key exchange protocols, although it can be applied to authentication protocols in general. The model not only captures a large class of attacks but al...

Anti-acetylcholine receptor antibody titres have been monitored in the sera of 19 myasthenic patients treated with plasma exchange combined with a three month period of immunosuppressive therapy. In general the post-exchange titres stabilised at below pre-exchange levels for prolonged periods which were associated with clinical improvement. In seven instances recurrence of symptoms occurred and...

Fab arm exchange by a stabilized anti-IL-31 IgG(4)S228P monoclonal antibody (mAb) was studied using physiologically relevant antibody concentrations and thiol exchange conditions, and directly compared to that of matched wild type IgG(4) (IgG(4)wt) and IgG(1) control antibodies. In vitro arm exchange between the test mAbs and a purified IgG(4)wt exchange partner was monitored using capillary is...

PURPOSE This study focused on the anti-microbial protein human lactoferrin (hLF) commonly found in saliva, and tried to develop biocompatible dental materials that have higher anti-microbial effects. METHODS A lyophilized cation exchange resin was added to tissue conditioner at 4 wt% and 8 wt%. The amount of hLF binding to the tissue conditioner and their anti-microbial effect against Candida...
