COMPOSITIONS FOR ONE STEP COLORIMETRIC ANALYSIS AND METHODS OF USING SAME

摘要

The present invention provides compositions and kits comprising porous substrates that retain staining solutions, wherein the staining solutions comprise one or more staining agents that form visible complexes with proteins or other molecular species of interest in a gel. The invention further provides methods for identifying biological moieties in a sample, using the compositions and kits of the invention, with superior signal to noise ratios that do not require destaining procedures.
