Biuret assay sensitivity
WebAug 1, 2024 · The sensitivity of the assays was measured as a slope of the regression lines and ranged from 0.04 (Biuret) to 12.07 (TBPB). The Biuret method was the least sensitive [33] (0.04 unit signal/mg protein) among other colorimetric paper protein assay methods examined. This method is considered to be independent of protein composition … WebOct 14, 2024 · It has less variability than others (i.e., Bradford assay), and it can be used to measure a wide range of protein concentration. Moreover, its sensitivity can be increased by performing the assay in the presence of plasmonic nanosensors as in the SPR-BCA (Surface Plasmon Resonance–BCA) assay proposed by Liu et al . With this assay the …
