Method of Processing and Testing Powdered Samples Using Immunochromatographic Strip Tests

Abstract

A method and kit for processing and testing powdered samples are provided herein. The powdered sample is combined with a fluid to produce a slurry or liquid suspension, and the slurry is contacted with an immunochromatographic test strip containing detectable reagents that are immunoreactive with an analyte to be detected in the sample. The method is particularly useful for the analysis of agricultural products or crops, such as the identification of recombinant grains.

         14 . A kit for detecting a recombinant protein in a powdered, genetically modified agricultural crop sample comprising: 
 a buffer, wherein the buffer is capable of forming a slurry free from excess liquid with the powdered sample;    an immunochromatographic strip; and,    antibodies, wherein the antibodies are combined with the sample prior to contacting the sample with the buffer.    
     
     
         15 . The kit of  claim 14  wherein the sample is a grain.  
     
     
         16 . The kit of  claim 14  wherein the sample is corn.  
     
     
         17 . The kit of  claim 14  wherein the sample is a genetically modified plant.  
     
     
         18 . The kit of  claim 14  wherein the protein is a recombinant  Bacillus thuringiensis  protein.  
     
     
         19 . The kit of  claim 14  wherein the protein is a Cry1Ab protein.  
     
     
         20 . The kit of  claim 14  wherein the protein is a Cry1Ac protein.
