International Classification:

C07C22900

US Classification:

562444, 564167

Abstract:

A method for enhancing the conversion of a phenol substrate to a product by a peroxidase enzyme comprises the steps of reacting a conjugate comprising a detectably labeled phenol with a peroxidase enzyme in the presence of an enhancing reagent, the enhancing reagent conmprising an inorganic salt, an organic compound having the formula wherein when X is B(OH) , Y is I, or wherein when X is OH, Y is a halogen, or Q-R wherein Q is a linear or branched 1-12 heteroatom alkyl wherein the heteroatoms are selected from C, N, O, and S, wherein the bonds connecting the heteroatom alkyl chain are single or double, wherein any carbon atom in the heteroatom alkyl chain optionally includes a substituent selected from âOH, âCOOH, âNH , and âSH, and wherein R is selected from âOH, âCOOH, âNH , and âCH ; or mixtures of the inorganic salt and the organic compound. A compound having the formula: wherein R is âCH OH, âCOOH, and n is 1-8.

Abstract:

A method for performing a peroxidase-based assay by reacting a peroxidase enzyme with a soluble organic p-hydroxyphenyl-containing compound having the formula: wherein Q is a linear or branched 1-12 heteroatom alkyl wherein the heteroatoms are selected from C, N, O, and S, wherein the bonds connecting the heteroatom alkyl chain are single or double, wherein any carbon atom in the heteroatom alkyl chain optionally includes a substituent selected from âOH, âCOOH, âNH , and âSH, and wherein R is selected from âOH, âCOOH, âNH , and âCH ; and converting the soluble organic p-hydroxyphenyl-containing compound into a stable insoluble product which becomes highly fluorescent after illumination, upon excitation.

Abstract:

A microfluidic system, device, and method are disclosed. The microfluidic system may include a first microfluidic channel and a second microfluidic channel, each of which are carrying one or more objects. There is an intersection between the first and second microfluidic channels where one or more objects from the first microfluidic channel impact one or more objects from the second microfluidic channel under hydrodynamic forces. The impact causes the objects to deform and the deformation of objects can be analyzed to determine properties of the object.
