| 20090081722 | SITE-SPECIFIC LABELING OF AFFINITY TAGS IN FUSION PROTEINS - The present invention provides methods and fluorescent compounds that facilitate detecting and labeling of a fusion protein by being capable of selectively binding to an affinity tag. The fluorescent compounds have the general formula A(B)n, wherein A is a fluorophore, B is a binding domain that is a charged chemical moiety, a protein or fragment thereof and n is an integer from 1-6 with the proviso that the protein or fragment thereof not be an antibody or generated from an antibody. The present invention provides specific fluorescent compounds and methods used to detect and label fusion proteins that contain a poly-histidine affinity tag. These compounds have the general formula A(L)m(B)n wherein A is a fluorophore, L is a linker, B is an acetic acid binding domain, m is an integer from 1 to 4 and n is an integer from 1 to 6. The acetic acid groups interact directly with the positively charged histidine residues of the affinity tag to effectively label and detect a fusion protein containing such an affinity tag when present in an acidic or neutral environment. | 03-26-2009 |

| 20100279314 | COMPOSITION AND METHOD FOR MEASURING THALLIUM INFLUX AND EFFLUX - The present invention relates to methods for detecting the activity of an ion channel in a cell. The methods comprise providing a loading buffer solution to a cell that has an ion channel. The loading buffer comprises at least one thallium indicator (e.g., an environmentally sensitive, luminescent dye) and a physiological concentration of chloride ions. The methods further comprise providing a stimulus buffer to the cell, wherein the stimulus buffer comprises thallium (e.g., thallium ions). Providing the stimulus buffer causes thallium influx into the cell through the ion channel. After providing the stimulus buffer, the luminescence (e.g., fluorescence) of the dye in the cell is detected. The luminescence of the dye can change in the presence or absence of thallium. The methods may be used to measure influx or efflux of thallium through an ion channel. | 11-04-2010 |
