摘要:
A homogeneous high throughput assay is described which screens compounds for enzyme inhibition, or receptor or other target binding. Inhibition (or binding) by the library compounds causes a change in the amount of an optically detectable label that is bound to suspendable cells or solid supports. The amounts of label bound to individual cells or solid supports are microscopically determined, and compared with the amount of label that is not bound to individual cells or solid supports. The degree of inhibition or binding is determined using this data. Confocal microscopy, and subsequent data analysis, allow the assay to be carried out without any separation step, and provide for high throughput screening of very small assay volumes using very small amounts of test compound.
摘要:
A method for determining the level of tyrosine kinase activity in a biological sample is disclosed. The method employs an anti-phosphotyrosine antibody as both the capture agent and the detecting agent. The detecting antibody is labeled with a fluorescent label, for instance, Cy5, Cy5.5 or Cy7 or a lanthanide ion, such as europium, as the signal generating entity. The method is particularly well suited to high throughput screening, for example, for compounds which modulate tyrosine kinase activity.
摘要:
The present invention encompasses polypeptides that comprise a chemokine receptor binding sequence and are useful in determining the affinity of a compound for a chemokine receptor. Substitution of one of the amino acids of the C-terminal region of the polypeptide with a cysteine enables the polypeptide to be detectably labelled without loss of receptor binding activity and without the problems inherent in radioiodine labelling. Methods for use of the polypeptides in competitive binding assays are also disclosed.
