Aspects of the disclosure relate to lateral flow assays having a number of different detection zones tuned to extend the dynamic range of the assay in indicating concentration of a hazardous contaminant in a test sample. Some aspects relate to assay reader devices configured with instructions to generate a result representing the concentration of the hazardous contaminant in the test sample based on some or all of the detection zones.

High dynamic range assays in hazardous contaminant testing

The present application relates to antibodies that bind to small molecules such as cyclophosphamide, ifosfamide, and analogs thereof, and immunological assays for determining the presence and/or quantifying the amount of cyclophosphamide and/or ifosfamide in a sample. By way of example, such immunological assays can be used for environmental testing.

Cyclophosphamide analogs for use as immunogens and assay conjugates for an immunoassay of cyclophosphamide and ifosfamide

Dimeric cationic lipids

The present invention provides novel amide-based cationic lipids of the general structure: ##STR1## or a salt, or solvate, or enantiomers thereof wherein; (a) Y is a direct link or an alkylene of 1 to about 20 carbon atoms; (b) R.sub.1 is H or a lipophilic moiety; (c) R.sub.2, R.sub.3, and R.sub.4 are positively charged moieties, or at least one but not all of R.sub.2, R.sub.3, or R.sub.4 is a positive moiety and the remaining are independently selected from H, an alkyl moiety of 1 to about 6 carbon atoms, or a heterocyclic moiety of about 5 to about 10 carbon atoms; (d) n and p are independently selected integers from 0 to 8, such that the sum of n and o is from 1 to 16; (e) X.sup.- is an anion or polyanion and (f) m is an integer from 0 to a number equivalent to the positive charge(s) present on the lipid; provided that if Y is a direct link and the sum of n and p is 1 then one of either R.sub.3 or R.sub.4 must have an alkyl moiety of at least 10 carbon atoms. The present invention further provides compositions of these lipids with polyanionic macromolecules, methods for interfering with protein expression in a cell utilizing these compositions and a kit for preparing the same.
