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 .

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.

Hoechst 33258 is a blue to blue-green fluorescent live cell dye that can label DNA. Hoechst 33258 can specifically bind to the minor groove of DNA (and tends to bind to A/T-rich DNA), resulting in a significant increase in fluorescence intensity. Hoechst 33258 can cross the cell membrane and cause changes in DNA structure, such as G2/M phase arrest. Hoechst 33258 can bind to live or fixed cells, and the fluorescence intensity increases with increasing solution pH. As a DNA-specific probe, Hoechst 33258 can be used to detect DNA content, analyze cell cycle, etc. The excitation wavelength of Hoechst 33258 is 350-365 nm, and the emission wavelength is 460-490 nm .

Synonyms: HOSu; 1-Hydroxy-2,5-pyrrolidinedione
N-Hydroxysuccinimide (HOSu; 1-Hydroxy-2,5-pyrrolidinedione) is a covalent crosslinker commonly used in bioconjugation technology with a primary amine group. N-Hydroxysuccinimide reacts with amino groups (-NH2) to form a stable amide bond, which can modify amino-containing biomolecules. N-Hydroxysuccinimide can be used, for example, for protein labeling with fluorescent dyes and enzymes, surface activation of chromatography supports, microbeads, nanoparticles and microarray slides, and chemical synthesis of peptides. N-Hydroxysuccinimide has a wide range of applications in biomaterial synthesis (such as collagen, chitosan crosslinking), drug delivery systems (such as hydrogel preparation) and tissue engineering .

DQ-BSA-Red is a bovine serum albumin labeled with a red fluorescent dye that can be used to detect lysosomal activity. The excitation wavelength and emission wavelength of DQ-BSA-Red are 590 nm and 620 nm, respectively. The BSA molecule in DQ-BSA-Red is labeled with high concentration of red fluorescent dye in multiple sites, which shows high fluorescence self-inhibition. Once DQ-BSA-RED enters the lysosome, DQ-BSA is cleaved by lysosomal proteases, resulting in unquenched and released fluorescent fragments, emitting bright fluorescence. Inactivated lysosomes are unable to degrade the BSA protein and thus have a lower or even no fluorescent signal .
