Synonym: Cholesterol Assay Kit

General description

Cholesterol is an important component of mammalian cell membranes where it functions in intracellular transport, cell signalling, and maintaining membrane fluidity. Within the blood, cholesterol circulates as both the free acid and as cholesterol esters. Controlling serum cholesterol has an important therapeutic role as elevated cholesterol levels are associated with the development of atherosclerosis and cardiovascular pathologies. Recent evidence suggests a disturbance of cholesterol homeostasis contributes to the development of a chronic inflammatory state.

Cholesterol is predominantly produced in the liver. Abnormal cholesterol levels are implicated in coronary heart disease. Cholesterol is associated with breast cancer progression or inhibition. Tumour cells are capable of synthesizing their own cholesterol, which aids in cell proliferation. Increased cholesterol level is observed in cancers, especially in prostate cancer. Elevated serum cholesterol is observed in obesity.

Application

Cholesterol Quantitation Kit has been used to measure the total serum cholesterol level.

Suitability

Suitable for use with cell and tissue culture samples, urine, plasma, serum, and other biological samples.

Principle

The Cholesterol Quantitation Kit can also be used to determine the concentration of free cholesterol, cholesteryl esters, or both (total) present in a sample. In this kit, total cholesterol concentration is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/fluorometric (λ_ex = 535/λ_em = 587 nm) product, proportional to the cholesterol present.

Description

Cas Number : 1045-41-0

Synonyms : Gentiomycin C

Chemical structure: aminoglycoside
Gentamicin, also known as gentiomycin C, is an aminoglycoside, which is naturally produced by Gram-negative bacteria. This antibiotic functions by preventing protein synthesis.[1] Gentamicin sulfate prevents the growth of both Gram positive and Gram negative bacteria, in vivo and in vitro. In tissue culture, gentamicin sulfate is used to inhibit the growth of various strains of mycoplasma.[2].

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

Description

Silica gel is a type of stationary phase material used in column chromatography, a separation technique that separates components of a mixture based on their chemical properties. The silica gel 60 offered by Merck has a particle size of 0.040-0.063 mm, which is equivalent to 230-400 mesh according to the ASTM standard. This makes it suitable for use in column chromatography applications where a fine, uniform particle size is required for efficient separation of target compounds. Merck’s Silica Gel 60 is a high-quality product that is widely used in research and industrial laboratories for various chromatography applications.

RPMI 1640 Medium was developed at Roswell Park Memorial Institute in 1966 by Moore and his co-workers. A modification of McCoy′s 5A Medium, it was formulated to support lymphoblastoid cells in suspension culture, but it has since been shown to support a wide variety of cells that are anchorage-dependent. Originally intended to be used with a serum supplement, RPMI 1640 has been shown to support several cell lines in the absence of serum. It has also been widely used in fusion protocols and in the growth of hybrid cells. This medium is suitable for culturing human normal and neoplastic leukocytes.

RPMI-1640 medium formulation is based on the RPMI-1630 series of media utilizing a bicarbonate buffering system and alterations in the amounts of amino acids and vitamins. It is used for the culture of human normal and neoplastic leukocytes. RPMI-1640 also supports the growth of various types of cell cultures, like fresh human lymphocytes in the 72-hour phytohemagglutinin (PHA) stimulation assay.
