FITC (Fluorescein Isothiocyanate, 5-FITC) is an amine-reactive reagent for the FITC labeling of proteins, microsequencing of proteins, and peptides. 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.

| FITC Palmitate
FITC-Palmitate is a fluorescently labelled fatty acid derivative made by chemically coupling fluorescein isothiocyanate (FITC) with a long chain fatty acid, palmitic acid. Due to its combination of fat solubility and green fluorescent signals, it has a variety of uses in biomedical and cell biology experiments. |
| PGSK diacetate (5/6-mixture)
PGSK diacetate (5/6-mixture) is a metal ion-sensitive fluorescent probe that can penetrate cell membranes. PGSK diacetate can react with a variety of metal ions, including Fe2+, Cd2+, Co2+, Ni2+, Zn2+, etc. PGSK diacetate chelates Fe2+, resulting in fluorescence quenching, which can be restored when a membrane-permeable chelator is added, thereby reflecting the changes in the intracellular chelatable iron pool. The excitation/emission maxima of PGSK diacetate are 507/532 nm, respectively. |
| Dextran-Rhodamine B
Dextran-Rhodamine B (RB-Dextran) is a fluorescent marker made by combining rhodamine B fluorescent dye and dextran polysaccharide through a specific chemical reaction. RB-Dextran is a red fluorescent modified dextran polysaccharide formed by chemically labeling rhodamine B onto dextran molecules, which can be used in cell tracing, biofluid dynamics research and other fields, and its fluorescent properties can be used to track the distribution and metabolism of dextran in organisms and other processes. |
| N-Succinimidyl 6-(2,4-Dinitroanilino)hexanoate
N-Succinimidyl 6-(2,4-Dinitroanilino)hexanoate, the DNP-X acid modified by succinimidyl ester, is an amine-reactive building block for developing a probe, which can be recognized by anti-DNP antibodies. |
| FITC-Arachidonic Acid
FITC-Arachidonic Acid is a fluorescent labelled compound for biomedical research. FITC-Arachidonic Acid combines the biological activity of arachidonic acid and the fluorescent properties of FITC, and is suitable for the study of cellular signalling, lipid metabolism and so on. |
