Principles of Proline Measurement The most widely used method for proline quantification is the acid ninhydrin assay, developed by Bates et al. (1973). ...
Choosing the right eluent in chromatography is crucial—especially for ion exchange chromatography (also known as ion chromatography or IC)—as is the choice of the correct column. Both must work in harmony to achieve optimal separation performance. In chromatography, we often refer to the «triangle of dependency» – the interdependent relationship between analytes, the ...

Because steroid hormones are present in relatively low concentrations and often exist as a complex mixture of structurally similar compounds, their accurate identification and quantification require highly sensitive and specific analytical techniques. Advanced methods, such as liquid chromatography-tandem mass spectrometry (LC-MS/MS), are indispensable tools. ...
The use of magnetic beads for purification yields superior results because they generate both higher product quantities and purities when compared to standard purification methods. Functionalized beads provide precise target protein binding and collection which lowers contamination and non-specific binding thus achieving greater purification in the final product. Drug development applications and ...
