Bicinchoninic Acid Assay - an overview ScienceDirect Topics

Bicinchoninic acid (BCA) assay or Smith assay is a copper-based colorimetric assay for total protein quantification. BCA rely on the formation of a Cu 2 +–protein complex in a basic environment, followed by reduction of the Cu 2 + to Cu + (Smith et al., 1985).The amount of Cu 2 + that is reduced is proportional to the amount of protein present in solution.

Linking Increased Isotope Fractionation at Low ...

Feb 11, 2022 Slow microbial degradation of organic trace chemicals (“micropollutants”) has been attributed to either downregulation of enzymatic turnover or rate-limiting substrate supply at low concentrations. In previous biodegradation studies, a drastic decrease in isotope fractionation of atrazine revealed a transition from rate-limiting enzyme turnover to membrane permeation as …

Newtonian Fluid - an overview ScienceDirect Topics

Newtonian fluids as simple as water already present their own considerable challenges for micro-scale swimmers. At such a small scale, the characteristic Reynolds number Re, which represents the ratio between inertial and viscous forces, is lower than unity, thus inertia is negligible and time-reversibility applies (low-Re regime). This means that reciprocal motions, such as the opening …
