BSA Protein

Manninotrionate potassium is a hapten that can be conjugated to bovine serum albumin (BSA) or to ovalbumin. In vivo antisera generated from manninotrionate potassium-protein conjugates produce weak precipitation reactions with bovine lung galactan, guaran, gum arabic, and larch arabinogalactan.

Aminostigmine hydrochloride is a Cholinesterase (ChE) inhibitor. Aminostigmine hydrochloride is a carbamate nerve agent precursor with a K_d of 6.6 mM for BSA. Aminostigmine hydrochloride exerts toxicity through carbamoylation of the enzyme active site and binds to serum albumin to reduce free toxicity. Aminostigmine hydrochloride is useful for studying atomic-level binding interactions between toxic compounds and carrier proteins .

Lys-VBOD is a Fluorescent probe for lysosomal viscosity monitoring and live cell imaging. Its detection mechanism depends on viscosity: increased viscosity restricts the twisting of the double bond between the indole and BODIPY fluorophore, as well as the rotation of the single bond between quinoline and BODIPY, which reduces non-radiative decay and leads to enhanced fluorescence intensity in high viscosity environments; it also features a morpholine group that provides lysosome-targeting properties, allowing it to localize to lysosomes for viscosity detection. The probe has excitation/emission wavelengths of Ex/Em = 602/637 nm, and its fluorescence intensity shows a good linear relationship with log-transformed viscosity values. Lys-VBOD is stable across a wide pH range of 5.35 to 10.74, is not affected by macromolecules and proteins like BSA, has a fluorescence lifetime that increases with viscosity, and can visualize real-time lysosomal viscosity changes in live cells under Dexamethasone (HY-14648) stimulation[1].
