• • Workflow of 1D SDS-PAGE and IEF

  Protein separation is a crucial step in molecular biology research. Two commonly used protein separation techniques are one-dimensional SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) and Isoelectric Focusing (IEF). These techniques separate proteins based on their different characteristics, utilizing molecular weight and isoelectric point (pI) differences, respectively. This article will detail the workflows of 1D SDS-PAGE and IEF.

  One-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (1D SDS-PAGE) and isoelectric focusing electrophoresis (IEF) are widely used protein separation techniques in biological research. These methods exploit differences in the electrophoretic behavior of proteins under various conditions to achieve separation and analysis.

• • Circular Dichroism Spectrum of Proteins

  Circular dichroism (CD) spectroscopy is a commonly used spectral technique for studying the secondary structure of biological macromolecules such as proteins and nucleic acids. This technique is based on the differential absorption of left- and right-handed circularly polarized light by chiral centers in molecules, such as α-helices and β-sheets in proteins.
