dc.description.abstractMethods were established for the estimation of bovine lactoferrin by enzyme-linked immunosorbent assay (ELISA) on microtitre plates and nitrocellulose (dot assay). Mfinity-puri:fied antibodies to bovine lactoferrin were prepared and conjugated to horseradish peroxidase by the periodate method. Conjugates with enzymatic and immunological activity had an apparent molecular weight of 65 or 95 kd. Four methods of ELISA on microtitre plates and three dot assays were developed. ii Differences between the seven assays could be attributed to the absorption capacity of the solid phase and the types of conjugates and substrates used. The range of the two successful quantitative assays were 3-lOOOng lactoferrin/ml (sandwich) and 60-8000ng lactoferrin/ml (competitive), while the qualitative dot assays had a range of 1-lOOJ.lg lactoferrin/ml. More replicates would be required to reduce variability. Results from these assays generally corresponded to results from ROCKET electrophoresis. Dot assay on nitrocellulose has a greater potential for reproducible and quantitative assays than assay on microtitre plates, because of the greater adsorption capacity of the nitrocellulose. In addition, the dot assays are faster and lend themselves to more applications than either ROCKET electrophoresis or ELISA on microtitre plates. The ELISA developed in this project appear to be the first alternatives to radial immunodiffusion and ROCKET electrophoresis for the measurement of bovine lactoferrin.en
