closed-HMRG is an HMRG (HY-D2379) with a closed spiro-ring structure. HMRG is a fluorescent dye, which serves as the fluorescent active product generated by enzyme-activated fluorescent probes targeting proteases and glycosidases. Its detection mechanism relies on the intramolecular spirocyclization equilibrium: HMRG itself exists in an open non-spirocyclic structure under physiological pH, which maintains a conjugated π system and produces strong fluorescence; whereas its probe precursors (such as Leu-HMRG, Ac-GlyPro-HMRG and βGal-HMRG) exist in a closed spirocyclic form and show no fluorescence due to the disruption of the π-conjugated system; when the target enzyme cleaves the substrate fragment linked to the probe precursor, the closed spirocyclic structure converts to the open structure of HMRG, restoring the conjugated system and generating a strong fluorescent signal. Its detection wavelength is Ex/Em = 501/524 nm .
Cat. No.: HY-115692
CAS No.: 1887057-34-2
Cat. No.: HY-D2984
CAS No.: 1308789-62-9
Synonyms: SNAP-PEG-NH2
Target:
Research Areas:
BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins .

Research Areas:
Sulfo-QSY21-NHS is an N-hydroxysuccinimide ester derivative fluorescent quencher that reduces the fluorescence intensity of paired fluorophores via proximity effect and relieves quenching after linker extension induced by mechanical force. Sulfo-QSY21-NHS can label streptavidin through NHS ester bioconjugation and be integrated into fluorescence-based molecular tension sensors to map the mechanical forces of cell surface receptors. Sulfo-QSY21-NHS also serves as a quencher for cysteine cathepsin-targeted quenched fluorescent substrate probes, and is widely used in studies related to breast cancer, colorectal cancer and lung adenocarcinoma .

Research Areas:
RO 16-6491 Free base is a selective, reversible inhibitor of monoamine oxidase type B (MAO-B), exhibiting high affinity and specificity for binding sites in human frontal cortex mitochondria and platelet membranes. RO 16-6491 demonstrates a fast dissociation of bound radioactivity at 20 degrees C, indicating its dynamic binding properties. RO 16-6491 also acts as a substrate for MAO-B, suggesting that its oxidation may produce a stable intermediate responsible for its potent inhibitory effects. RO 16-6491 serves as an excellent radioligand probe for investigating the regional tissue distribution of MAO-B in various physiological and pathological states.

ALDH2 probe 5 is a ALDH2 isoform-selective fluorescent probe with an emission wavelength centered at 494 nm. ALDH2 probe 5 is a turn-on fluorescent substrate for ALDH2; in its unreacted aldehyde form, twisted intramolecular charge transfer (TICT) occurs, resulting in fluorescence quenching. After ALDH2 probe 5 is catalytically oxidized to carboxylate by ALDH2, TICT is inhibited and fluorescence is significantly enhanced. ALDH2 probe 5 enables highly sensitive quantitative imaging of ALDH2 activity in recombinant enzymes, live cells, blood, tissue homogenates, and the brains of living mice. ALDH2 probe 5 can be used for studies related to neuroinflammation .
