AG Scientific Inc Trehalose Dihydrate 25 G
D-(+)-Trehalose is among the most effective sugars for the stabilization of proteins against damage caused by desiccation or freezing and is noted for its high water-retention capabilities, protecting cells against multiple environmental stressors. It is rarely used as a replacement for conventional sweeteners. It is more commonly used as a cryoprotectant in a variety of cell freezing media. A wide array of implemental enzymes, probes, substrates, antibodies and biology reagents can be kept in trehalose, saving on expensive freezer storage.D-(+)-Trehalose dihydrate is a non-reducing disaccharide, yielding 2 moles of D-glucose upon acid hydrolysis. It is an inducer of autophagy and has properties allowing it to stabilize partially unfolded proteins and inhibit protein aggregation.Trehalose dihydrate has been demonstrated to decrease lysosomal amyloid precursor protein (APP) and inhibits polyglutamine-mediated protein aggregation both in vivo and in vitro.

Medchemexpress LLC D-α-Hydroxyglutaric acid | 13095-47-1 | 98.0% | 148.11 | 1 ML
D-α-Hydroxyglutaric acid is the primary metabolite that accumulates in the neurometabolic disorder D-2-hydroxyglutaric aciduria. It acts as a weak competitive antagonist of α-ketoglutarate (α-KG), inhibiting multiple α-KG-dependent dioxygenases with a Ki of 10.87 mM. This compound increases reactive oxygen species (ROS) production, binds to and inhibits ATP synthase, and suppresses mTOR signaling. It also accumulates in human cancers with neomorphic mutations in IDH1 and IDH2 genes.

AdipoGen n-Octyl-beta-D-glucopyranoside
Chemical. CAS 29836-26-8. Formula C14H28O6. MW 292.4. Non-ionic detergent for the functional solubilization, isolation, purification and crystallograpy of membrane proteins. Mild, non-denaturing detergent that is used for the solubilization and reconstitution of membrane-bound proteins in their native state and for the preparation of lipid vesicles. Its well-defined chemical structure, small uniform micelles and high water solubility make it superior to most other non-ionic detergents for membrane solubilization. The high critical micelle concentration 0.7% of n-octylglucoside facilitates ready removal from final protein extracts by dialysis or gel filtration. Used in lysis and solubilisation buffers for bacterial lipoprotein preparations, mitochondrial extracts or for determination of protein content by BCA assay. Can be used in 2D electrophoresis.
