Synonyms: N-Acetylcysteine; N-Acetyl-L-cysteine; NAC
Acetylcysteine (N-Acetylcysteine) is a mucolytic agent that can cross the blood-brain barrier, which reduces the thickness of the mucus. Acetylcysteine is a ROS inhibitor. Acetylcysteine is a cysteine precursor, prevents hemin-induced ferroptosis by neutralizing toxic lipids generated by arachidonate-dependent activity of 5-lipoxygenases. Acetylcysteine induces cell apoptosis. Acetylcysteine also has anti-influenza virus activities. In addition, Acetylcysteine ​​is the most stable form of cysteine ​​during drug delivery and can be used in disulfidptosis studies .

MitoSOX Red is a live cell fluorescent probe that specifically targets mitochondria and is cell membrane permeable. MitoSOX Red enters mitochondria and is oxidized by superoxide but not by other ROS or RNS generating systems. The oxidized MitoSOX Red then binds to nucleic acids in mitochondria/nucleus, producing strong red fluorescence. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. In addition, superoxide dismutase (SOD) can prevent the oxidation of MitoSOX Red.
Excitation/emission wavelength: 510/580 nm.

CAS No.: 103404-75-7
Purity:  99.92%
Synonyms: D-(-)-Luciferin sodium; Firefly luciferin sodium; Beetle Luciferin sodium
D-luciferin sodium is the natural substrate of the enzyme luciferase (Luc) that catalyzes the production of the typical yellowgreen light of fireflies. The 560 nm chemiluminescence from this reaction peaks within seconds, with light output that is proportional to luciferase concentration when the substrate luciferin is present in excess. The luciferase (luc) gene is a popular reporter gene for research and agent screening. Chemiluminescent techniques are virtually background-free, making the luc reporter gene ideal for detecting low-level gene expression. As little as 0.02 pg of luciferase can be reliably measured in a standard scintillation counter. In addition to its role as a reporter of gene expression, luciferase is commonly used in an extremely sensitive assay for ATP . We of er the firefly luciferase (HY-P1004A), luciferin free acid (HY-12591A), as well as its water-soluble sodium salts (HY-12591) and potassium salts (HY-12591B) .

FITC (Fluorescein Isothiocyanate), is one of the green fluorescein derivatives widely used in biology. FITC has the characteristics of high absorptivity and excellent fluorescence quantum yield. The isothiocyanate group of FITC can be combined with amino, sulfhydryl, imidazole, tyrosyl, carbonyl and other groups on the protein, so as to achieve protein labeling including antibodies and lectins. In addition to its use as a protein marker, FITC can also be used as a fluorescent protein tracer to rapidly identify pathogens by labeling antibodies, or for microsequencing of proteins and peptides (HPLC). The maximum excitation wavelength of FITC is 494 nm. Once excited, it fluoresces yellow-green at a maximum emission wavelength of 520 nm. In addition, FITC is also a hapten that can induce contact hypersensitivity (CHS) and induce an atopic dermatitis model .

DNase I is an enzyme that degrades DNA. DNase I is mainly produced by digestive system organs, such as the pancreas and parotid gland. Three types of DNase I are known in mammals: pancreatic type, parotid type, and pancreatico-parotid type. DNase I plays a key role in the cleavage of extracellular DNA, and is critical for limiting inflammatory responses and maintaining homeostasis. DNase I is responsible for digesting extracellular nucleoproteins, which may be essential for preventing autoimmune reactions. Decreased DNase I activity may be associated with the occurrence and development of systemic lupus erythematosus (SLE). DNase I (filtered) is filtered through a 0.22 μM membrane and is not tested for pyrogenicity .
