Web5 uur geleden · Cui et al. find that arginine depletion and inflammation reduces nuclear localization of arginyl-tRNA synthetase, which influences alternative splicing via condensate-like serine/arginine ... WebWhile the biuret method is sensitive in the range 0.5 to 2.5 mg protein per assay, the Lowry method is 1 to 2 orders of magnitude more sensitive (5 to 150 μg). The main disadvantage of the Lowry method is the number of interfering substances; these include ammonium sulfate, thiol reagents, sucrose, EDTA, Tris, and Triton X-100.
A stock BCA solution contains the following ingredients in a highly alkaline solution with a pH 11.25: bicinchoninic acid, sodium carbonate, sodium bicarbonate, sodium tartrate, and copper(II) sulfate pentahydrate. The BCA assay primarily relies on two reactions. First, the peptide bonds in protein reduce Cu ions from the copper(II) sulfate to Cu (a temperature dependent reaction). The amount of Cu reduce… Web10 aug. 2024 · The difference however is that the formed BCA/copper complex absorb light much more strongly than those generated by the biuret assay alone greatly increasing the assays sensitivity.
