摘要:
The invention is directed to enhanced methods for detecting an analyte of interest in situ, by immunoassay, or by hybridization comprising binding an enzyme-labeled conjugate molecule to an analyte of interest in the presence of a redox-inactive reductive species and a soluble metal ion. The enzyme catalyzes the conversion of the inactive reductive species to an active reducing agent, which in turn reduces the metal ion to a metal atom thereby providing an enhanced means of detecting the analyte via metal deposition.

The present invention relates to an anesthetic composition containing a fluoroether compound and a physiologically acceptable Lewis acid inhibitor. This composition exhibits improved stability and does not readily degrade in the presence of a Lewis acid.
摘要:
A method for fluoromethylating halogenated alcohols. The method includes the step of providing an alpha-halogenated alcohol of the formula R1C(CX3)2OH, wherein R1 is selected from the group consisting of hydrogen and alkyl groups. The alpha-halogenated alcohol is reacted with a first compound of the formula CH2(OR2)2 in the presence of an acid catalyst to form an acetal. The resulting acetal is then chlorinated with a chlorinating agent to form a chloride compound of the formula R1C(CX3)2OCH2Cl. The chloride compound is then converted to a fluoride compound of the formula R1C(CX3)2OCH2F using a fluorinating agent.
摘要:
Fluorescent conjugates suitable for use in flow cytometry and other biological applications. The fluorescent conjugates comprise an antibody having a polymeric dye bound thereto. The polymeric dye is preferably enhanced by a hydrophobic and conformationally restrictive moiety either bound thereto or in close association therewith. The hydrophobic and conformationally restrictive moiety is preferably derived from a cyclodextrin. The polymeric dye comprises a polymeric entity having signal-generating groups, such as aminostyryl pyridinium dye residues attached thereto. The fluorescent conjugates exhibit exceptional stability characteristics and avoid many of the problems of energy transfer, bio-conjugability, and solubility.
