Cat. No.: HY-66019
CAS No.: 3326-32-7
Synonyms: Fluorescein 5-isothiocyanate
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 .

Br-DAPI is a marker dye in DAPI series. DAPI is a fluorescent dye that binds strongly to DNA. It binds to the AT base pair of the double-stranded DNA minor groove, and one DAPI molecule can occupy three base pair positions. The fluorescence intensity of DAPI molecules bound to double-stranded DNA is increased by about 20 times, and it is commonly observed with fluorescence microscopy, and the amount of DNA can be determined based on the intensity of fluorescence. DAPI cannot penetrate intact cell membranes and is commonly used for staining damaged and fixed cells . Storage: Keep away from light.

Synonyms: Dextran 3; Dextran D3; Dextran T3(MW 2400-3600)
Dextran T3 (Dextran 3; Dextran T3(MW 2400-3600)) is a neural tracer and intestinal permeability probe that can move anterogradely and retrogradely in neuronal axons by passive diffusion. Dextran T3 (MW 3,000) is able to permeate across the intestinal epithelial cell membrane in the presence of cholera toxin-induced cytoskeletal disturbance. Dextran T3 (MW 3,000) is used as a fluorescent marker to rapidly label developing neurons (such as Xenopus retinal ganglion cells) and to assess intestinal barrier function. It can be used to study axonal transport in neuroanatomy and permeability changes in intestinal pathophysiology. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .
