Gallocyanine is a small molecule blue dye used to stain nuclei. It is known to inhibit Dickkopf-1 (Dkk1), an antagonist of the Wnt pathway. Gallocyanine can disrupt the interaction of Dkk1 with its receptor LRP5/6 (IC50 = 3 μM), thereby activating Wnt/β-catenin signaling. Modulation of the Dkk1-LRP5/6 interaction via gallocyanine has been shown to inhibit prostaglandin J2-induced tau phosphorylation at serine396 in primary cortical neurons in vitro.

Phalloidin-AMCA conjugate is a blue fluorophore that specifically labels filamentous actin (F-actin). It consists of aminomethylcoumarin (AMCA; ex/em max = 350/450 nm) conjugated with phalloidin , a mycotoxin that binds F-actin. Phalloidin-AMCA conjugate is used in fixed and permeabilized tissue sections, cell cultures, or cell-free experiments.

Phalloidin-TRITC is a TRITC labeled, red fluorescence probe for F-actin . Phalloidin, bound to actin filaments, reacts covalently with amino acids Glu-llT, Met-ll9, and Met355, which are very close to the nucleotide binding site.

Isosulfan blue is a blue dye utilized for identifying lymph vessels during lymphangiography and sentinel lymph node biopsies in breast cancer. However, Isosulfan blue may cause allergic reactions during breast cancer operations [1] [2].

Calcein Blue is a blue-fluorescent, short-term dye.

AA-dUTP [sodium salt] is a fluorescent dye used for staining cDNA.

Z-Val-Lys-Met-AMC TFA is a fluorescent substrate used for detecting the β-secretase activity of cathepsin B.

D-Val-Leu-Lys-pNA dihydrochloride (D-VLK-pNA dihydrochloride) is a chromogenic substrate for enzyme proteases. It is catalytically cleaved and hydrolyzed by plasmin, releasing p-nitroaniline (pNA), which can be measured spectrophotometrically at 405 nm to assess plasmin activity.

MMP-3 Fluorogenic Substrate, a compound designed for matrix metalloproteinase-3 (MMP-3) activity quantification, releases 7-methoxycoumarin-4-acetyl (Mca) upon MMP-3 cleavage. Mca's fluorescence, with excitation and emission maxima at 328 and 420 nm respectively, serves as a measurable indicator of MMP-3 activity.

Rose bengal lactone (C.I. Solvent Red 141) is a rose bengal lactone stain commonly used to stain the nuclei of plant and animal cells.

Direct Red 80 (Sirius Red), a tetra azo dye, is used to detect amyloid and enhance the birefringence of collagen fibers in tissue sections.

AD-1 is a novel near-infrared fluorescence (NIF) probe capable of monitoring all Aβ species in early Alzheimer's disease models. It exhibits excellent blood-brain barrier penetration and low cytotoxicity.

BP Fluor 405 picolyl azide is an advanced fluorescent probe that incorporates a copper-chelating motif to enhance the effective concentration of Cu(I) at the reaction site. The rate of the CuAAC reaction depends on the concentrations of all reagents, including copper; therefore, increasing the effective concentration of copper at the reaction site can substantially accelerate the CuAAC reaction rate without the need to increase the concentrations of azide reagents or copper. Additionally, using pyridyl azide instead of traditional azides allows for the copper catalyst concentration to be reduced by at least tenfold without compromising labeling efficiency. In summary, the introduction of the pyridyl group into the azide probe significantly boosts the sensitivity of alkyne detection, proving especially valuable for detecting low-abundance targets or situations requiring a significant increase in signal intensity.
