D-Val-Leu-Lys-pNA acetate (S-2251 acetate) is a chromogenic peptide substrate that serves as a characteristic substrate for plasmin and plasminogen. D-Val-Leu-Lys-pNA acetate acts as a sensitive substrate for the DFE27 serine protease derived from Bacillus subtilis DC27. Catalyzed by plasmin, D-Val-Leu-Lys-pNA acetate binds and hydrolyzes to release p-nitroaniline (pNA), which can be detected colorimetrically at 405 nm as a measure of fibrinolytic activity .

MCE MCE Total Superoxide Dismutase (SOD) Activity Colorimetric Assay Kit (Xanthine Oxidase-NBT Method) is based on the xanthine oxidase–NBT chromogenic system and quantitatively determines total SOD activity in various biological samples by measuring the inhibition of NBT reduction to formazan in the xanthine/xanthine oxidase–generated superoxide system at 560 nm. It is suitable for the determination of SOD activity in cell or tissue homogenate supernatants, whole blood, erythrocyte extracts, serum, and other biological samples.

Ehrlich's Reagent is an indicator with p-dimethylaminobenzaldehyde (HY-Y0015) as its core component. Ehrlich's Reagent is mainly used for the identification of enterobacteria, non-fermentative bacteria, fastidious bacteria and anaerobic bacteria, as well as the detection of indole derivatives and amines. It turns pink, red or purple when a positive reaction occurs. Ehrlich's Reagent undergoes colorimetric reactions with urobilinogen, indican, phenol, allantoin, tryptophan and uric acid, and forms yellow-green products when reacting with sulfur derivatives .

CAS No.: 2361979-91-9
NRh-Cu is a highly sensitive near-infrared fluorescence turn-on indicator and Cu 2+-selective probe (λex=680 nm, λem=740 nm). When NRh-Cu interacts with Cu 2+, it undergoes a structural transition from a non-fluorescent spirocyclic state to a fluorescent ring-opened state, which drives the enhancement of fluorescence emission. NRh-Cu can be used for Cu 2+ imaging in live cells and in vivo .

Cat. No.: HY-B1306R
CAS No.: 61-78-9
Synonyms: p-Aminohippuric acid (Standard)
4-Aminohippuric acid (p-Aminohippuric acid) (Standard) is the analytical standard of 4-Aminohippuric acid (HY-B1306). This product is intended for research and analytical applications. 4-Aminohippuric acid (p-Aminohippuric acid) is a coordination ligand for metal ions (such as Cu 2+, Fe 3+, Hg 2+) and a functionalization reagent for nanomaterials. 4-Aminohippuric acid can coordinate with metal ions or modify the surface of materials such as carbon nanotubes and gold nanoparticles through amino and carboxyl groups. 4-Aminohippuric acid can form stable complexes with metal ions or participate in the synthesis of nanomaterials as a reducing agent/stabilizer, enriching metal ions or giving nanoparticles peroxidase-mimicking activity. 4-Aminohippuric acid can be used to construct highly sensitive electrochemical sensors or colorimetric sensors to detect and quantitatively analyze heavy metal ions such as copper, iron, and mercury in environmental water samples and biological samples. 4-Aminohippuric acid may also be a biomarker for attention-deficit/hyperactivity disorder (ADHD) .
