The effective molar absorption coefficient at 492 nm for the ZnHx(PAR)2 complex at pH 7.4 in buffered water solution is 71,500 M− 1 cm− 1, and the dissociation constant of the complex in these conditions is 7.08 × 10− 13 M2. To confirm these values and estimate the range ...
Gold nanoparticleBSAdiscrete conjugatemolar ratiospectroscopyultracentrifugeDiscrete biomolecule-nanoparticle (NP) conjugates play paramount roles in nanofabrication, in which the key is to get the precise molar extinction coefficient of NPs. By making best use of the gift from a specific separation ...
B. Calculate the Degree of Labeling 1. Calculate molarity of the protein: • ε = protein molar extinction coefficient (e.g., the molar extinction coefficient of IgG is ~210,000 M -1 cm -1 ) • A max = Absorbance (A) of a dye solution measured at the wavelength maximum (λ...

His-tagged MBP-TEV-HttEx1Qn eluted from this column at 200 mM KCl, and their concentrations were determined from their absorbance at 280 nm using an extinction coefficient of 67840 M−1 cm−1. Removal of MBP from HttEx1 MBP-TEV protease, produced using the plasmid pRK1043 (Addgene, ...
calculate the molar extinction coefficient of a biomolecule with a MW of 300 if a 5.0 mM solution in a 1.2 cm cuvette has an absorbance of 0.50 at 340nm. You are given a range of wavelengths for maximum absorbance for absorption spectroscopy. Why...
denatured and ineffective. The pH of the medium affects protein conformation because certain amino acids become protonated/deprotonated at different pH, the effect is much more pronounced if the enzyme's active site contains these types of residues. ...
