Cell Biolabs’ Rhodamine Competitive ELISA Kit provides a convenient method for the detection of total rhodamine in extracts from cells, tissue, serum, plasma, or foods. The total content of rhodamine in unknown samples is determined by comparison with a rhodamine standard curve. Each kit provides sufficient reagents to perform up to 96 assays, including standard curve and unknown protein samples. The kit has a detection sensitivity limit of 1 µM rhodamine.
