pubmed:abstractText |
Fluorescence Recovery After Photobleaching (FRAP) has been used extensively in the study of transport and binding in biological media in vitro. The present study adapts and further develops FRAP so that it may be utilized for the in vivo quantification of binding parameters. The technique is validated in vitro by measuring mass transport and binding parameters for the Concanavalin A/Mannose binding system (a diffusion-limited system). The pseudo-equilibrium constant (the product of the equilibrium constant and the total concentration of binding sites) for this system was determined to be 26 +/- 15 which compares favorably with literature values ranging between 16 and 32. The applicability of this technique to measure parameters for monoclonal antibody/antigen interactions in a thin tissue preparation such as the rabbit ear chamber tissue preparation is also examined. Unlike other methods for measuring binding parameters, this is the only technique which has the potential to measure parameters relevant to antibody delivery in vivo. The proposed technique is noninvasive and does not require a priori knowledge of, independent measurement of, or variation in the concentration of binding sites or total concentration of binding species.
