Abstract: 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.

Abstract: Compositions and methods for detecting the activity of an ion channel in a cell are described. The methods include providing a loading buffer solution to the cell, where the loading buffer includes a thallium ion indicator and optionally chloride ions, and providing a stimulus buffer that includes thallium ions to the cell. Providing the stimulus buffer can cause thallium ion influx into or efflux out of the cell through the ion channel. After providing the stimulus buffer, a change in at least one optical property of the thallium ion indicator is detected in response to thallium influx or efflux, thereby detecting the activity of the ion channel.
