Chemicals & Small Molecules

12-Doxyl stearic acid, a derivative of stearic acid featuring a 4,4-dimethyl-3-oxazolinyloxy (DOXYL) group, functions as a hydrophobic spin label. This compound is prevalently utilized in research to investigate the molecular characteristics of membranes and hydrophobic proteins.

DC4 crosslinker, an 18Å mass spectrometry-cleavable crosslinking reagent, features two intrinsic positive charges facilitating the fragmentation of cross-linked peptides into their constituent peptides through collision-induced dissociation or in-source decay. Initial fragmentation leads to cleavage adjacent to the positive charges, enabling the identification of cross-linked peptides as pairs of ions with precise mass separation. Furthermore, the resultant intact peptide fragments can undergo further fragmentation, producing a sequence of b- and y-ions for peptide identification.

Chondroitin sulfate sodium (Chondroitin polysulfate sodium) is a naturally occurring glycosaminoglycan extracted from animal cartilage that is used as a food supplement with antitumor activity, reduces inflammatory mediators and apoptotic processes, and decreases the production of inflammatory cytokines, iNOS, and MMPs, and may be used in the study of Osteoarthritis.

6-O-Propynyl-2'-deoxyguanosine, a click chemistry reagent with an alkyne group, facilitates research in various biochemical [1] contexts.

Didocosanoin, a diacylglycerol, incorporates the saturated 22-carbon fatty acid, docosanoic acid, at both of its positions.

trans-Petroselinic Acid (Δ6-trans-Octadecenoic Acid) is a trans-isomer of fucoidan and an isomer of oleic acid, which can be extracted from milk fat of cows, goats and ewes, as well as human breast milk.

2,7-Dichlorodihydrofluorescein (DCFH2) serves as a non-fluorescent probe, which becomes the highly fluorescent 2′,7′-dichlorofluorescein (DCF) for detecting reactive oxygen species [1] [2].

5-Sulfosalicylic acid, a sulfonated salicylic acid derivative, is effective against breast cancer cell lines with less toxicity [1] and possesses antioxidant activities [2].

800CW NHS ester is a near-infrared probe used for labeling lysine residues (λ max = 776 nm) [1][2].
