7-Azido-4-methylcoumarin is a selective coumarin-based fluorescent probe for hydrogen sulfide (H2S). In the presence of H2S, the aromatic azido group of 7-Azido-4-methylcoumarin is selectively reduced to produce the fluorescently active 7-amino-4-methylcoumarin (AMC). 7-Azido-4-methylcoumarin binds to the coumarin/phenol-binding site of BSA, the aglycone-binding site of UGT1A6, and the substrate-binding site of SULT1A1, respectively. 7-Azido-4-methylcoumarin retains its fluorescent properties after covalent binding, acts as a fluorescent H2S probe, and does not react with cysteine, homocysteine or glutathione (Ex/Em = 340/445 nm) .

MN551 is a covalent modulator of SOCS2 and CISH, with selectivity for SOCS2 and CISH over SOCS4. MN551 covalently modifies Cys111 in the SH2 domain of SOCS2 and Cys144 in the EF loop of the CISH SH2 domain, while only minimally modifying Cys471 in the BG loop of the SOCS6 SH2 domain. MN551 increases the thermal stability of the recombinant SOCS2-ElonginB-ElonginC complex and competitively blocks the binding of SOCS2 to its substrate; when delivered via the prodrug MN714, it blocks the intracellular recruitment of substrates by SOCS2. MN551 can serve as a chemical probe for investigating the biological functions of SOCS2 and its CRL5 complex, and also act as an E3 ligase-binding module in proteolysis-targeting chimeras (PROTACs) .

Synonyms: Dextran 3; Dextran D3; Dextran T3(MW 2400-3600)
Dextran T3 (Dextran 3; Dextran T3(MW 2400-3600)) is a neural tracer and intestinal permeability probe that can move anterogradely and retrogradely in neuronal axons by passive diffusion. Dextran T3 (MW 3,000) is able to permeate across the intestinal epithelial cell membrane in the presence of cholera toxin-induced cytoskeletal disturbance. Dextran T3 (MW 3,000) is used as a fluorescent marker to rapidly label developing neurons (such as Xenopus retinal ganglion cells) and to assess intestinal barrier function. It can be used to study axonal transport in neuroanatomy and permeability changes in intestinal pathophysiology. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .

2A3 (2-aminopyridine-3-carboxylic acid imidazolide) is a covalent probe reagent for Selective 2'-Hydroxyl Acylation analyzed by Primer Extension (SHAPE) that targets the RNA ribose 2'-OH group. 2A3 efficiently permeates the biological membranes of Gram-negative bacteria, Gram-positive bacteria, and mammalian cells. 2A3 exhibits no base bias and specifically labels conformationally flexible, unpaired regions within RNA. 2A3 forms covalent adducts by acylating the 2'-OH groups of flexible RNA residues. When combined with SHAPE-MaP (mutational profiling) sequencing technology, these modification sites are converted into detectable mutational signals, thereby accurately reflecting local RNA backbone flexibility and base-pairing status. 2A3 is primarily utilized in molecular biology and transcriptomics research, including the resolution of RNA structuromes in living cells, the study of RNA folding regulatory mechanisms, and the investigation of non-coding RNA functions .

KB05yne is a site-selective, alkyne-functionalized electrophilic "probe" fragment probe designed for covalent ligand discovery, with preferential reactivity toward specific cysteine residues in proteins. KB05yne strongly labels wild-type target proteins (e.g., CDKN2AIP, HPCAL1) but does not label their cysteine-to-alanine mutants, confirming site-specific cysteine reactivity. KB05yne can be used for the discovery and optimization of site-specific covalent ligands, and is applicable to proteins with diverse structures and functions, especially in studies targeting cysteine residues in cancer-related or difficult-to-purify proteins .

ER Tracker Yellow (BDNCA-346) is a Fluorescent probe for targeted visualization of temperature at the endoplasmic reticulum. Its detection mechanism depends on temperature, with fluorescence intensity decreasing at higher temperatures due to preferential non-radiative processes; this intensity reversibly returns to baseline when cooled, provided the probe does not precipitate or degrade. It localizes specifically to the endoplasmic reticulum, where it may covalently attach to biomacromolecules via a thiol-reactive moiety, and its fluorescence remains stable after cell fixation; its fluorescence intensity is unaffected by physiological pH ranges of 5.0–8.0 and free Ca²⁺ concentrations of 0–800 μM. Its excitation/emission wavelength is Ex/Em = 559/581 nm[1].
