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 .

Synonyms: mPEG5000-Maleimide
mPEG5000-Mal (mPEG5000-Maleimide) is a PEG-derived selective covalent binding agent for sulfhydryl groups (RSGs), which can form irreversible thioether bonds with sulfhydryl groups under near-neutral conditions via the maleimide group. The mechanism of action of mPEG5000-Mal can be divided into two categories: firstly, as an enzyme modifier, it binds to target proteins through hydrophobic interactions, hydrogen bonds, and van der Waals forces, altering the protein's secondary structure; secondly, as a nanoparticle surface modifier, it covalently binds to sulfhydryl groups on the surface of red blood cells, changing the surface properties and morphology of the red blood cells, leading to their phagocytosis by macrophages of the reticuloendothelial system. mPEG5000-Mal can react with free cysteine in proteins, increasing the apparent molecular weight of the modified protein by 10-15 kDa for detection purposes. mPEG5000-Mal can enhance the thermal stability and catalytic activity of enzymes, and improve the macrophage targeting of nanoparticles, enabling targeted drug delivery. mPEG5000-Mal can be applied in enzyme engineering research in the food industry and in oncology, assisting radiotherapy by inhibiting tumor-associated macrophage infiltration and enhancing anti-tumor immune responses .
