Collagenase, Type IV (EC 3.4.24.3) is a microbially derived matrix metalloproteinases (MMPs) and zinc peptidase. Collagenase, Type IV degrades type IV collagen and type VII collagen, the main components of the basement membrane, and can also decompose basement matrix and elastin.

2-NBDG is a fluorescently-labeled deoxyglucose analog that is used primarily to directly monitor glucose uptake by living cells and tissues. It is also used as a topical contrast reagent for the detection of neoplasia. 2-NBDG can be used in real-time confocal, high-resolution, or wide-field fluorescence microscopy as well as in flow cytometry. The probe can be excited by the Argon laser at 488 nm to give the environment-sensitive fluorescence. It has lower photostability than the rhodamine-based fluorescent probes.

3X FLAG peptides are FLAG-tagged peptides containing three repeats of the Asp-Tyr-Lys-Xaa-Xaa-Asp motif. 3X FLAG peptide can be used for protein separation and purification, and competitive elution with target proteins.

IPTG is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.

FITC-Dextran (MW 4000) is a fluorescent probe for fluorescein isothiocyanate (FITC) dextran (Ex=495 nm; Em=525 nm). FITC-Dextran (MW 4000) can be used as a marker to reveal heat shock-induced cell damage and to study the early and late stages of apoptosis. FITC-Dextran (MW 4000) can also be used for cell permeability studies, such as blood-brain barrier permeability and determination of the extent of blood-brain barrier disruption.

DSPC (1,2-Distearoyl-sn-glycero-3-phosphorylcholine) is a cylindrical-shaped lipid. DSPC is used to synthesize liposomes, and is the lipid component in the lipid nanoparticle (LNP) system.

Fluo-4 AM is a cell-permeable Ca²⁺ (calcium ion) indicator (Ex/Em = 485/526 nm).

1-Ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride is a carbodiimide reagent that can form nucleic acid and compounds with amide bonds. 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride accelerates the formation reaction of esters, amides, and peptides, as a condensing and dehydrating agent, which are often used for polynucleotide synthesis, anhydroxydation, lactonization and esterification.

Collagenase, Type II is a microbially derived matrix metalloproteinases (MMPs) and zinc peptidase. Collagenase, Type II breaksdown collagens1, 3, 5, 7, 8, 10, fibronectin, gelatin, aggrecann.

Cremophor EL-40, a polyoxyethylene castor oil derivative, is a nonionic surfactant. Cremophor EL-40 is widely employed to improve dissolution and delivery of agents.

Pronase E (Activity ≥ 7000 U/g) is a mixture of proteolytic enzymes that is obtained from Streptomyces griseus and could digest protein into individual amino acids.

DiO is a long-chain carbocyanine dye. Carbocyanine dyes are widely used as Di to label cells, organelles, liposomes, viruses and lipoproteins.

Thioflavin T is a cationic Benzothiazole dye that shows enhanced fluorescence upon binding to amyloid in tissue sections. Excitation max.: ~385 nm (free); ~450 nm (bound); Emission max.: ~445 nm (free); ~485 nm (bound).

Collagenase, Type I is a microbially derived matrix metalloproteinases (MMPs) and zinc peptidase. Collagenase, Type I breaks down collagens 1, 3, 7, 8, 10, gelatin, proteoglycans, aggrecan.

Rhod-2 is a high-affinity visible light excitation wavelength Ca²⁺ fluorescent probe, Rhod-2, AM is an acetyl methyl ester derivative of Rhod-2, which has cell membrane permeability and can easily enter cells with simple culture. Once it enters the cell, it is sheared by its lactesterase to produce Rhod-2 without membrane permeability, which remains in the cell to perform the corresponding physiological functions. Maximum excitation/emission wavelength: 549/578 nm.

PEG8000 can be used for phage precipitation, isolation of plasmid DNA, and promotion of flat end-junction reactions.

DiD is a long-chain carbocyanine dye. Carbocyanine dyes are widely used as Di to label cells, organelles, liposomes, viruses and lipoproteins (Ex/Em = 633/665 nm).

Rhodamine dyes are membrane-permeable cationic fluorescent probes that specifically recognize mitochondrial membrane potentials, thereby attaching to mitochondria and producing bright fluorescence, and at certain concentrations, rhodamine dyes have low toxicity to cells, so they are commonly used to detect mitochondria in animal cells, plant cells, and microorganisms.

CY5 is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis. CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction. Below, we introduce the labeling method of protein antibody labeling, which has certain reference significance.

Proteinase K (Protease K) is a nonspecific serine protease that is useful for general digestion of proteins. Proteinase K is active in the presence of SDS or urea and over a wide range of pH (4-12), salt concentrations, and temperatures. Proteinase K can be use for promoting methods of viral nucleic acid extraction, and detection.
