Abstract: Kits and processes for detecting analytes present in solid materials, especially soil or foodstuffs. The kits and processes utilize a tubular apparatus, fitted or fittable with a piston, cap and filter, as a scoop and both to extract the analyte from the solid material into the extraction liquid and to separate the extraction liquid from the solid material.
Abstract: Improvements in immunoassays for chlorpyrifos and compounds structurally related to chlorpyrifos are achieved by using standards of increased stability.
Abstract: A carbohydrate-free polypeptide coded for by a human DNA sequence of 309 nucleotides is immunologically reactive with monoclonal antibody against the human DF3 breast carcinoma-associated antigen. The nucleotide sequence is also useful as a probe to reveal restriction fragment length polymorphisms in human DNA.
