An extremely rapid assay technique for antibodies has been developed utilizing protein A or protein G bound to Perfusion Chromatography support matrices. Either dilute or concentrated samples are directly injected on a column that selectively binds antibody, which is quantitated directly by elution and UV absorbance. Due to the unique mass transport characteristics of the supports, total assay cycle times are typically 1 minute or less, with assays as short as 15 seconds possible. The assay system can accurately quantitate a 100,000:1 or greater dynamic range in sample concentration without sample dilution, is extremely repeatable and is easy to automate with conventional HPLC systems. Assay of antibodies in a wide range of sample types has been demonstrated.
