What is Hydrophobic Interaction Chromatography (HIC)? Principle of Hydrophobic Interaction Chromatography (HIC) The principle of Hydrophobic Interaction Chromatography (HIC) is based on the interactions between the hydrophobic regions of sample protein molecules and a hydrophobic stationary phase or matrix. This principle allows for the separation and purification of proteins based on their hydrophobicity. In HIC, … Read more

What is Flash chromatography? Principle of Flash column chromatography The principle of flash chromatography revolves around the rapid movement of the eluent, a liquid, through a short glass column under gas pressure, typically nitrogen or compressed air. The glass column is packed with a stationary phase consisting of an adsorbent material with a defined particle … Read more

What is Chromatography?

What is a stationary phase? What is the mobile phase? Types of Chromatography Here is the Types of Chromatography; Type of Chromatography Description Gas … Read more

What is Two-Dimensional (Crossed) lmmunoelectrophoresis? Principle of Two-Dimensional (Crossed) lmmunoelectrophoresis The principle of Two-Dimensional (Crossed) Immunoelectrophoresis involves the combination of two distinct electrophoretic steps to separate and identify proteins based on their charge, size, and antigen-antibody interactions. The technique consists of the following steps: The principle of Two-Dimensional Immunoelectrophoresis exploits the migration characteristics of proteins … Read more

What is Immunoelectrophoresis? Immunoelectrophoresis is a biochemical approach for protein separation and characterization that is based on electrophoresis and antibody-antigen interactions. It uses immunodiffusion and electrophoresis techniques to identify and analyse specific antigens within a protein mixture. The immunoelectrophoresis procedure begins with electrophoresis, which separates the antigen mixture into its distinct components. This is accomplished … Read more

What is Polyacrylamide Gel Electrophoresis (PAGE)? Definition of Polyacrylamide Gel Electrophoresis (PAGE) Polyacrylamide Gel Electrophoresis (PAGE) is a technique used to separate and analyze proteins or nucleic acids based on their mobility in a porous polyacrylamide gel matrix under the influence of an electric field. Types of Polyacrylamide Gel Electrophoresis (PAGE) There are several types … Read more

What is SDS-PAGE? Definition of SDS-PAGE SDS-PAGE is a technique used to separate proteins based on their molecular weight by using a gel matrix and the denaturing agent sodium dodecyl sulfate (SDS). Overview of SDS PAGE SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) is a popular method for studying protein mixtures. By sorting proteins depending on … Read more

What is Mass Spectrometry (MS)? Definition of Mass Spectrometry (MS) Mass Spectrometry (MS) is an analytical technique used to identify the chemical composition of a sample by measuring the mass-to-charge ratio of its ions, resulting in a mass spectrum that reveals the molecular and structural information of the sample. Mass Spectrometry Principle Mass Spectrometry operates … Read more

What is Solid State Fermentation (SSF)? Definition of solid state fermentation Solid State Fermentation (SSF) is a fermentation method that involves the growth of microorganisms on solid support, such as grain brans or oil seed cakes, without a free-flowing aqueous phase. It is used in various industries to produce valuable metabolites, including antibiotics, enzymes, and … Read more

What is IR Spectroscopy? Principle of IR Spectroscopy Infrared (IR) spectroscopy operates on the basis of analyzing the interaction between infrared radiation and a molecule. In terms of wavelength, the infrared region most frequently employed for analyzing organic compounds lies between 2,500 and 16,000 nm, corresponding to a frequency range of 1.9 × 10^13 to … Read more
