Abstract: The present invention relates to novel 6-acetylmorphine analogs, and methods for their synthesis and use. Such analogs are designed to provide a convenient linkage chemistry for coupling under mild conditions to a suitable group on a target protein, polypeptide, solid phase or detectable label.

Abstract: This disclosure relates to methods and kits for determining the presence and/or amount of one or more analytes in a keratinized structure (e.g., hair) sample.

Abstract: Methods for assessing the condition of keratinized structures, including hair, in particular methods to determine the condition of keratinized structures in relation to suitability for analysis of analytes of interest in a test sample, are presented. The methods comprise contacting the keratinized structure with a non-proteolytic reducing agent and an optional proteolytic agent. The methods further include inspection of the hair sample, or measurement of free protein eluted from the keratinized structure, after reduction and optional proteolysis to determine condition prior to analyte identification and quantitation by known techniques such as immunoassays.
