Collection: Post-Translational Modification

Post-Translational Modification — includes chromogenic and fluorogenic reagents such as indolyl galactopyranoside derivatives, tetramethylbenzidine, and calcein, used in the detection of enzyme activity and biochemical markers. This group serves as substrates or detection reagents in proteomics studies related to post-translational modification of proteins.

Post-Translational Modification Reagents are used in ELISA assays, beta-galactosidase histochemical staining, and colorimetric detection of enzyme activity using substrates such as TMB or 4-chloro-1-naphthol. Proteomics and molecular biology researchers use fluorometric reagents such as calcein to measure calcium levels, while galactopyranoside substrates are used in reporter gene assays and visualization of protein expression in tissues or cells.

Selection considers the form of supply, either ready-to-use solution or powder that requires dissolution, the detection wavelength suitable for the instrument, and compatibility with the assay system used. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
