N-(Azido-PEG3)-N-Fluorescein-PEG3-acid is a PEG-based PROTAC linker which contains azide, fluorescein and carboxylic acid moieties. N-(Azido-PEG3)-N-Fluorescein-PEG3-acid is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

Cresol Red sodium is a colorimetric pH indicator. Cresol Red sodium serves as an optical sensor for monitoring carbonic anhydrase-catalyzed reactions and as a colorimetric dye that responds to hydrogen ions generated during DNA synthesis. Cresol Red sodium can be used in the research of hepatitis A and COVID-19.

(E)-BSPOTPE is the E configuration of BSPOTPE (HY-W856375A). BSPOTPE binds Human serum albumin (HSA) (HY-P1956), exhibits aggregation-induced emission (AIE) phenomenon. BSPOTPE shows selectivity for albumin (such as HSA and BSA), but has no obvious fluorescence response to other proteins and DNA. BSPOTPE can be used as fluorescent probe for HSA.

DCDAPH (Compound 2c) is a novel smart NIRF probe for detection of β-amyloid (Aβ) plaques (λ_ex/λ_em=597/665 nm in PBS). DCDAPH shows high affinity for Aβ aggregates (K_i=37 nM, K_d=27 nM). DCDAPH shows good blood brain barrier permeation and can meet most of the requirements for the detection of Aβ plaques both in vitro and in vivo.

BODIPY FL Thapsigargin is a potent green fluorescent dye. BODIPY FL Thapsigargin inhibits intracellular SERCA-type Ca2+ pumps present in the sarcoplasmic/endoplasmic reticulum. BODIPY FL Thapsigargin used for investigation of thapsigargin binding sites in live cells.

CytoTrace Red CMTPX is a cell permeable long-term cell tracer (Ex=577 nm, Em=602 nm).

AMC-GlcNAc (compound 1) is a potent fluorogenic probe for detection and characterization of β-hexosaminidase enzyme activity. AMC-GlcNAc enables continuous monitoring by turn-on fluorescence and fluorescence signal is constant over a wide pH range (Ex=325 nm, Em=390 nm). AMC-GlcNAc enables ratiometric fluorescence detection with high sensitivity and low background, which can be used to screen for recombinant dispersin B activity in E. coli cell lysate.

Hoechst 33342 analog 2 is a marker dye in Hoechst series. Hoechst is A live nuclear marker dye. Hoechst binds to the grooves in the DNA double strand, which tends to be A/ T-rich DNA strand. Although it binds to all nucleic acids, the A/ T-rich double strand DNA significantly enhances fluorescence intensity Therefore,Hoechst dye can be used for living cell labeling. The fluorescence intensity of Hoechst dye increases with the increase of pH of solution.

7-Methoxycoumarin-3-carboxylic acid, SE can be used for the synthesis of hydrophilic dye compound 12. Compound 12 shows a homogeneous distribution inside the cell and represents a suitable probe for viscosity measurements in the cytoplasm.
