A vital component in many research fields is the ability to measure bacterial growth for fermentation, antibiotic effectiveness, synthetic biology, and food safety. Estimating bacterial growth ...

Researchers from the NIST Center for Nanoscale Science and Technology (CNST) and the University of Maryland have for the first time used photothermal induced resonance (PTIR) to characterize ...

Transferrin is a glycoprotein with a molecular weight of 80 kDa, synthesized in the liver. Each transferrin molecule can bind up to two iron atoms for distribution to cells. The half-life of ...

Fluorescence spectra are often subject to significant distortions. These are largely predictable and are caused by concentration-dependent Inner Filter Effects (IFE). It is therefore the ...

The success of next generation sequencing or western blotting is often affected by sample quantity and purity. To assess these parameters, researchers measure sample absorbance or fluorescence.

Proteins containing the appropriate amino acids are absorbent to light on the UV-spectrum, specifically light that has peak wavelengths of 260 – 280 nanometers (nm). This makes it simple to analyze ...
