The present disclosure embodies compounds of Formula I, methods of use thereof, and kits thereof:  that are useful in connection with the detection of analytes of all types (e.g., biological molecules such as proteins, organic molecules, natural or synthetic molecules). The disclosure is particularly applicable to detection of proteins and nucleic acids using all types of membrane-based assays by techniques such as Western blotting, Dot blotting, Southern blotting, and Northern blotting.

Hemicyanine dyes

The present invention provides a chemiluminescent ink formulation, comprising: a phthalocyanine metal catalyst; a visible dye; and a solvent. The formulation is useful in catalyzing a chemiluminescent reaction, by admixing for example, luminol or isoluminol with an oxidizing agent, a base and the chemiluminescent ink formulation to emit light.

Phthalocyanine formulation and uses thereof

Multifunctional molecular weight protein ladders and methods of making thereof are disclosed herein that are useful for determining the molecular weight of a test protein and/or the relative mass or amount of the test protein in a protein separation assay, such as gel electrophoresis or western blotting. Also included are compounds of Formula I (e.g., mono acetylated MP-11 NHS ester) that may be used to label purified proteins of the protein ladder. The MP-11 label protein ladder can be detected on a blotting membrane by exposing the microperoxidase to a suitable substrate, such as a chromogenic substrate or a chemiluminescent substrate.

Multifunctional protein molecular weight ladders

The present invention provides novel compounds and methods for hydrocyanines derived from near-infrared cyanine dyes, as reactive oxygen species probes in imaging. In certain embodiments, the present invention provides reduced dyes as substrates for ELISA and Western blots.

Application of reduced dyes in imaging

The present invention provides near-infrared fluorogenic and/or chromogenic formulations, methods, systems and kits. Upon contacting an azine with an oxidant and a peroxidase, the azine is converted to an azine derivative which is both visibly colored and fluorescent. This invention also provides high sensitive methods to detect biological molecules, showing better sensitivity than chemiluminescence methods. Advantageously, the formulation and reaction is free of luminol or luminol derivatives.

Fluorogenic and chromogenic substrate

The present invention relates to non-isotopic immunoassays for thiopurine methyltransferase (TPMT). The immunoassays of this invention may be homogenous or heterogenous, in which detection of the TPMT-catalyzed reaction product relies upon specific binding of antibody to 6-MMP or other TPMT-catalyzed reaction products. Preferred embodiments of this invention include a Rapid Immunomigration Cassette and an assay carried out in ELISA assay format.
