Webwhere (for proteins in water measured at 280 nm): Ext (Tyr) = 1490, Ext (Trp) = 5500, Ext (Cystine) = 125; The absorbance (optical density) can be calculated using the following formula: Absorb (Prot) = E (Prot) / Molecular_weight. Two values are produced by ProtParam based on the above equations, both for proteins measured in water at 280 nm. WebA molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. Therefore, when used in gel … WebMay 15, 2009 · In general, like DSL, if you assumje the protein has the simplest shape, the relationship is: R (nm) = 0.006 M^1/3 (M is in Dalton).
