20120135420 | Method for detecting the presence of target bacteria or a target component carbohydrate antigen thereof - A process is disclosed for separating a carbohydrate antigen from a Gram-positive or Gram-negative bacteria in a purified form that contains no more than 10% protein. The separated antigen is coupled to an affinity column, over which polyclonal antibodies to the same bacteria are chromatographed and recovered in a purified form that exhibits high specificity and sensitivity in immunoassays for the raw carbohydrate antigen corresponding to the purified antigen on the column. A particularly preferred form of rapid immunochromatographic assay employing the purified antibodies, which assay is very useful as an aid to rapid diagnosis of diseases caused by bacteria, is disclosed. | 05-31-2012 |
20090011436 | Dry Chemistry, Lateral Flow-Reconstituted Chromatographic Enzyme-Driven Assays - A lateral flow chromatographic assay format for the performance of rapid enzyme-driven assays is described. A combination of components necessary to elicit a specific enzyme reaction, which are either absent from the intended sample or insufficiently present therein to permit completion of the desired reaction, are predeposited as substrate in dry form together with ingredients necessary to produce a desired color upon occurrence of the desired reaction. The strip is equipped with a sample pad placed ahead of the substrate deposit in the flowstream, to which liquid sample is applied. The sample flows from the sample pad into the substrate zone where it immediately reconstitutes the dried ingredients while also intimately mixing with them and reacting with them at the fluid front. The fluid front moves rapidly into the final “read zone” wherein the color developed is read against predetermined color standards for the desired reaction. Pretreatment pads for the sample, as needed, (e.g. a lysing pad for lysing red blood cells in whole blood) are placed in front of the sample pad in the flow path as appropriate. The assay in the format of the invention is faster and easier to perform than analogous wet chemistry assays. | 01-08-2009 |
