WebWhen the molecular weight is above 400, less than 10 % of the dose is absorbed. Excretion of the ingested PEG which is not absorbed takes place largely as the unchanged substance in the faeces. After parenteral administration the substance is mainly excreted in the urine. PEGs are not readily absorbed through intact skin. Web1 OD 260 Unit = 40 μg/ml ssRNA. 1 OD 260 Unit = 33 μg/ml ssDNA. ss oligo concentration (ug/ml) = OD 260 x MW x 1000 / ε 260. where MW = molecular weight of oligo (non-phosphorylated) and ε 260 = extinction coefficient of oligo at 260nm. A path length of 1 cm is assumed for the absorbance.
WebData table of molecular weight of common materials The molar mass of a substance, also often called molecular mass or molecular weight (although the definitions are not strictly identical, but it is only sensitive in very defined areas), is the weight of a defined amount of molecules of the substance (a mole) and is expressed in g/mol. WebBiological mass spectrometry is an important analytical technique in drug discovery, proteomics, and research at the biology-chemistry interface. Currently, few hands-on opportunities exist for undergraduate students to learn about this technique. With the 2002 Nobel Prize being awarded, in part, for the development of biological mass spectrometry, …
