Chromogenic conjugates for color-based detection of targets are described. The conjugates comprise a chromogenic moiety such as rhodamine, rhodol or fluorescein. The chromogenic moiety is linked to a peroxidase substrate. The chromogenic conjugates can be used in immunohistochemical analysis and in situ hybridization. The conjugates can be used to detect 1, 2, 3 or more targets in a sample by color.

deprotection is especially effective with (trimethylsilyl)methyl isocyanide, and serum albumin can catalyze the elimination under physiological conditions. NMR and computational studies revealed that an imine-tautomerization step is often rate limiting, and the unexpected cleavage of the Si-C bond accelerates this step in the case with (trimethylsilyl)methyl isocyanide. Tetrazylmethyl-removal is compatible
