Glutamate, one of the two acidic proteinogenic amino acids, is also a key molecule in cellular metabolism. The synthesis of α-KG from glutamate by glutamate dehydrogenase is a key TCA cycle anaplerotic reaction. In humans, glutamate plays an important role both in amino acid degradation and disposal of excess or waste nitrogen. Within the mammalian nervous system, glutamate is the most abundant excitatory neurotransmitter. It…

Sufficient for 100 colorimetric or fluorometric tests.

Cell Line Origin Mouse BALB/c monocyte macrophage Cell Line Description Derived from a tumour in a female BALB/c mouse. Cell line produces IL-5 and lysozyme. Application J774A.1 cell line has been used to test the cytotoxicity of [1,2,3]triazolo[1,5-a]pyridinium salts (having leishmanicidal activity) from triazolopyridines. It has also been used to determine the antitrypanosomatid activity of flavonoid glycoside…

Castor oil is a triglyceride obtained from Ricinus communis. It has been used to study its impact on rat lens condition.Castor oilnhas also been used as a test reagent for studying the dose-response relationship and mechanism of action of Saccharomyces boulardii by utilizing the rat model of castor oil-induced diarrhea. Packaging 1 L in glass bottle 250 mL in glass bottle

Fluorescein sodium salt has been used as a solute to study microvessel permeability. It has been used as a test molecule to study blood barrier penetration. Water soluble fluorescent dye used in permeability and vascular perfusion studies due to its small molecular radius. Sodium fluorescein is used as a fluorescent tracer to study blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) permeability in rodent mode…

Immobilon ® ECL Ultra Western HRP Substrate is an ultra-sensitive reagent with long signal duration for the detection of horseradish peroxidase (HRP)-labeled antibodies on western blots. The intense signal created permits sensitive detection at the mid-to-low femtogram range using x-ray film or digital imaging systems.

BIOshell™ HPLC and UHPLC columns deliver maximum speed and efficiency for the separation of biomolecules on both HPLC and UHPLC systems. The novel, superficially porous silica particles (SPP), with pore sizes from 90 Å up to 1000 Å, allow the separation of glycans as well as of very large proteins.

The Fused-Core ® particle technology behind Ascentis ® Express columns delivers maximum speed and efficiency on both HPLC and UHPLC systems. The novel superficially porous silica particles (SPP) are available in three different particle sizes and two different pore sizes for optimal suitability from micro over UHPLC and HPLC to semi-preparative use.

For perfect high-performance liquid chromatography (HPLC) results, high-performance solvents are a must. LiChrosolv ® solvents are designed to optimally support analytical HPLC, fast chromatography, and LC-MS applications. They feature high degrees of UV transmittance, low particle counts, low acidity and alkalinity, and low evaporation residue levels making them ideal for reproducible separations.

The reagents for sample preparation have an important impact on the outcome of the measurement. In modern instrumental trace analysis, any impurity can disturb the measurement so acids with low impurities should be used to minimize the interference on the instrument signal. High purity Suprapur ® acids offer the most suitable purity of wet digestion materials with low impurities during the entire minimum shelf life.

SupraSolv ® solvents are developed specially for sample preparation in gas chromatography. Ideally suited for all GC applications including sensitive detection tasks in residue and environmental analysis, SupraSolv ® solvents offer you the security and reliability needed for today’s gas chromatography applications.

Our HybridSPE ® -PLus plates effectively remove phospholipids and proteins from biological matrices in a simple pass-through method for accurate and reproducible LC-MS analysis. Unlike other phospholipid removal SPE products on the market, the unique retention mechanism of HybridSPE ® allows for separation of even very hydrophobic analytes from phospholipid contaminants.     

Supel™ Swift HLB is a polymeric stationary phase for solid phase extraction (SPE) prior to instrumental analysis. It has both hydrophilic and lipophilic functional groups for the extraction of a broad range of compounds from aqueous samples. It retains analytes having diff erent polarities and Log P values due to its hydrophilic and lipophilic balance (HLB) property.
