Substrates
Research-Grade Enzyme Substrates for Life Science Discovery
High-purity enzyme substrates engineered for precision in kinase assays, protease assays, molecular biology, and drug discovery. Our enzyme substrates are manufactured to rigorous purity standards with full analytical data and reliable global delivery.
What Are Biochemical Substrates?
Enzyme substrates are in life science research, a substrate is a molecule upon which an enzyme acts — or a compound that generates a detectable signal (light, fluorescence, or color) when processed by a biological system. Substrates are the foundation of countless assays, from ELISA and Western blotting to reporter gene assays and high-throughput screening.
At ACUBIOCHEM, we manufacture and supply a curated portfolio of chemiluminescent substrates, luciferin derivatives, and fluorogenic substrates designed to deliver consistent, reproducible results across your experimental workflow.
Whether you need off-the-shelf catalog substrates or custom-synthesized derivatives for a novel assay platform, our team supports you from compound selection through scale-up.

🎯 Kinase Substrates
Peptide and protein substrates for kinase activity assays, including consensus phosphorylation site sequences, myelin basic protein (MBP), histone H1, and custom peptide substrates. Compatible with radiometric, fluorescent, and luminescent detection platforms for high-throughput screening.
🧬 Protease Substrates
Fluorogenic and colorimetric peptide substrates for serine, cysteine, aspartyl, and metalloprotease activity assays. Includes AMC/AFC-conjugated peptides, pNA substrates, FRET-based substrates, and native protein substrates for enzyme kinetics, inhibitor screening, and protease profiling.
⚡ Metabolic Enzyme Substrates
Substrates for NAD+/NADH-dependent dehydrogenases, oxidases, transferases, and other metabolic enzymes. Includes carbohydrate substrates, lipid substrates, amino acid substrates, and cofactor-dependent substrates for metabolic profiling, enzyme activity assays, and diagnostic reagent manufacturing.
⚙ Other Enzyme Substrates
Substrates for phosphatases, esterases, glycosidases, phosphodiesterases, nucleases, and other enzyme classes. Includes pNPP for phosphatases, MU-glucoside for glycosidases, cAMP/cGMP analogs for phosphodiesterases, and custom substrates for specialized assay development and enzyme characterization.
