With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter

Synonyms : DNA/RNA/protein extraction reagent, DNA/RNA/protein isolation reagent, DNA/RNA/protein purification reagent, TRI Reagent® cell pellet solution, cell pellet RNA extraction, cell pellet RNA isolation, cell pellet RNA purification, single step RNA extraction reagent, single step RNA isolation reagent, single step RNA purification reagent, total RNA extraction solution, total RNA isolation solution, total RNA purification solution, TRI Reagent® RNA Isolation Reagent.

TRI reagent® is a quick and convenient ready-to-use reagent useful for efficient total RNA extraction or for the simultaneous isolation of RNA, DNA and protein. TRI reagent® is a mixture of guanidine thiocyanate and phenol in a monophasic solution.

Homogenization or lysis of the tissue sample in TRI reagent® dissolves RNA, DNA and protein. The addition of chloroform or 1-bromo-3-chloropropane followed by centrifugation results in the separation of the mixture into three phases: an aqueous phase containing the RNA, the interphase containing DNA, and an organic phase containing proteins. Each of the components can then be isolated after separating the phases.

The method corresponds to DIN 38405-13 and is analogous to ISO 6703, EPA 335.2, APHA 4500-CN- E, and ASTM D2036-09 D.

This Spectroquant® Cyanide Reagent Test allows the accurate quantification of the free and readily liberated cyanide content in aqueous samples.

Method applied: Cyanide ions react with a chlorinating agent to form cyanogen chloride. In a follow-up reaction with 1,3-dimethylbarbituric acid in the presence of pyridine a violet dye (König reaction) is formed which is determined photometrically (only free cyanide. For readily liberated cyanide samples must be decomposed by digestion).

The Spectroquant® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.

All our Cell and Reagent Test Kits are equipped with the unique Live ID which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.

CAS number: 7782-42-5
Molecular weight:12.01
Synonyms: GNPs, xGnP® graphene nanoplatelets-grade C-750

xGnP® graphene nanoplatelets are a unique type of nanoparticle that have a platelet shape and are composed of short stacks of graphene sheets. Their distinctive size and morphology make them highly effective at providing barrier properties, as well as excellent electrical and thermal conductors due to their pure graphitic composition. Additionally, incorporating xGnP® graphene nanoplatelets can enhance mechanical properties such as stiffness, strength, and surface hardness of the matrix material.

Benzene is a six-membered aromatic compound that can undergo ionization induced by superhalogens, according to ab initio calculations. This compound is a frequently used industrial solvent but is also considered an air pollutant and a powerful carcinogen.

Benzene may be used in the formation of phenyl acetate by aerobic oxidation using Pd catalyst and acetic acid as solvent, formation of phenol by hydroxylation in the presence of mesoporous carbon nitride supported on vanadium catalyst and as a solvent to prepare nanoparticles of gallium nitride (GaN) by reacting Li3N and GaCl3 at 280°C.

Description

CAS number: 9007-43-6

Application

Cytochrome c has been identified as an important mediator in apoptotic pathways. The release of mitochondrial cytochrome c into the cytoplasm stimulates apoptosis and is commonly used as an indicator of the apoptotic process in the cell. Investigation on the effect of Paris Saponin I (PS I) on human gastric carcinoma cell growth (SGC7901 cells) have shown an elevated level cytoplasmic cytochrome c. Results are inhibition of proliferation in SGC7901 cells by inducing mitochondria-dependent apoptosis through cytochrome c.

Biochem/physiol Actions

The ready interconversion of cytochrome c between ferrous and ferric states makes it an efficient biological electron carrier. It plays a vital role in cellular oxidations in both plants and animals. Generally regarded as a universal link in the respiratory chain, it forms the essential electron-bridge between the respirable substrates and oxygen.
