5'-O-(4,4'-Dimethoxytrityl)-N2-isobutyryl-2'-O-methylguanosine 98%

Supplier: Enzo Life Sciences

Highly specific, cell permeable, and irreversible 20S proteasome inhibitor. Inhibits ubiquitin proteasome pathway in cell culture (IC50=1µM). It has been suggested that the natural product lactacystin acts as a precursor for clasto-lactacystin β-lactone and that the latter is the sole species that interacts with the proteasome. Inhibits cathepsin A. Leads to a reduction of adipogenesis. Induces neurite growth and inhibits cell cycle progression. 

Supplier: Enzo Life Sciences

Antiviral, antibacterial, antiprotozoal, immunomodulating, and antineoplastic cytostatic anthraquinone derivative. Induces DNA damage by intercalating into DNA and inhibiting topoisomerase II. Induces interstrand DNA cross-links and DNA-protein cross-links in cellular systems. Has been shown to be an inhibitor of DNA methylation.

Polaris™ NH₂ is an aminopropylsilane-covered silica that can be used in either reversed or normal phase conditions. Exhibit higher efficiencies for carbohydrate analysis than ionic gel-based columns

Supplier: MACHEREY-NAGEL

HMDS is weak TMS donor. If used as sole reagent, it is slow and not very effective. After addition of catalytic quantities (e.g., 1 %) of TMCS or as a mixture with TMCS it is a fast and quantitative reagent for trimethylsilylation of organic compounds.

Supplier: Enzo Life Sciences

The assay is designed to measure either MDA alone (in hydrochloric acid) or MDA in combination with 4-hydroxyalkenals (in methanesulfonic acid). It is based on the reaction of a chromogenic reagent, N-methyl-2-phenylindole with MDA and 4-hydroxyalkenals to yield a stable chromophore with maximal absorbance at 586 nm.

Supplier: VWR Chemicals

The level of volatile organic solvents in pharmaceutical raw materials or finished product is defined and monitored in accordance with ICH guidelines. Residual solvents are classified according to their risk assessment classes. A selection of residual solvent standards is now available from Avantor.

Supplier: MP Biomedicals

Erythromycin is a macrolide antibiotic that bind to the 50S ribosomal subunit and inhibit protein synthesis. This is an antimicrobial substance produced by the growth of certain strains of Streptomyces erythreus. It is a mixture consisting largely of erythromycin A with lesser amounts of erythromycins B and C.

Supplier: Cytiva (Formerly Pall Lab)

Simplifies clean-up and degassing of mobile phase solvents and other solutions. The versatile design fits most HPLC bottles, flasks, and containers, and eliminates the added steps of washing flasks and transferring mobile phase solvent from flask to reservoir.

Supplier: VARIAN

Microsorb™ C18 is an octadecylsilane-covered silica that has been bonded using monofunctional bonding agents under optimised conditions. This material is then endcapped with trimethylsilyl groups to minimise nonspecific binding, maximise mass recoveries and improve peak shape.

Supplier: Thermo Fisher Scientific

Asp-N protease is a highly specific endoproteinase used to improve sequence coverage in mass spectrometry protein identification applications.

Supplier: Thermo Fisher Scientific
