Brefeldin A is a lactone antiviral produced by the fungus Penicillium brefeldianum. [1] Brefeldin A inhibits protein transport from the endoplasmic reticulum to the golgi complex indirectly by preventing association of COP-I coat [2] to the Golgi membrane.
BioLegend is a global developer and manufacturer of antibodies and reagents used in biomedical research located in San Diego, California. [1] It was incorporated in June 2002 and has since expanded to include BioLegend Japan KK, where it is partnered with Tomy Digital Biology Co., Ltd. in Tokyo, BioLegend Europe in the United Kingdom, BioLegend GmbH in Germany, and BioLegend UK Ltd in the ...
To translate from mass to molar concentration, the dividend (molar mass and the divisor (1000) in the division change places, or, alternatively, distance to right is changed to distance to left. Substances with a molar mass around 1000g/mol (e.g. thyroxine) are almost vertically aligned in the mass and molar images.
If a stained cell divides, the dye is divided equally between the two daughter cells, resulting in both new cells having a CFDA-SE concentration approximately 50% that of the mother cell. A cell stained with CFDA-SE can be kept in culture for several days and fluorescence is detectable in cells following up to 8 successive cell divisions.
Propidium iodide (or PI) is a fluorescent intercalating agent that can be used to stain cells and nucleic acids.PI binds to DNA by intercalating between the bases with little or no sequence preference.
To normalize the concentration to a 10mm equivalent, the following is done: 0.6 OD X (10/3) * 50 μg/mL=100 μg/mL Most spectrophotometers allow selection of the nucleic acid type and path length such that resultant concentration is normalized to the 10 mm path length which is based on the principles of Beer's law.
The horizontal axis is the concentration of the ligand. As the Hill coefficient is increased, the saturation curve becomes steeper. In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration.
Neu5Gc is reported to be found in concentration in human cancers, as well as in fecal samples, suggesting that humans ingest Neu5Gc as part of their diets. Uptake is thought to be by macropinocytosis, and the sialic acid can be transferred to the cytosol by a sialin transporter. Humans have Neu5Gc-specific antibodies, often at high levels.
