Introduction: Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. It is a method used to separate molecules under the centrifugation field based on their sedimentation rate with the help of centrifugal force. It is also used to measure the physical properties of a molecule like molecular weight, density, shape, etc. If it is used for the separation of one type of materials from others is termed as preparative centrifugation and when used for…

separated and distributed between two phases, which are the mobile phases and stationary phase (1). There are multiple types of chromatograph, which includes paper chromatography, column chromatograph, retention chromatography, gas chromatography, liquid chromatography etc. Each technique has its own strengths and weaknesses, but all are useful in getting separations of different components (8). Since many colorful compounds today are not one color, but a composition of different colors, it is…

High Performance Liquid Chromatography Lab Abstract High performance liquid chromatography or HPLC is the process in which mixtures are physically separated according to their polarity. The lab conducted, the separation of dyes in grape Kool-Aid, demonstrated the concept. This was done to display how different alcohols and their concentrations have different polarities, in which ties into HPLC. The lab consists of testing Kool-Aid, water, and different concentrations of methanol and…

Paper Chromatography Paper Chromatography is an analytical method that is used to separate coloured chemicals substances, especially pigments. This is how paper chromatography is conducted: Materials Chromatography Paper (Can also be Coffee Filter) Large Beaker (max one litre) Paper Clips/Sellotape & Skewer Stick Water soluble black marker Water Procedure: Draw a ink dot with the marker on each one of the chromatography paper near the bottom end of the paper. Then stick or paper clip the…

Observe Ligand-Protein Interaction using Gel Filtration Chromatography (Phenol Red Binding to Bovine Serum Albumin) Introduction: Serum albumin is often known as blood albumin, and is the most abundant protein in humans and other animal plasma. Serum albumin is also known as a carrier protein by non-specifically binding several biomolecules. It is essential for maintaining the osmotic pressure that is needed for body fluids distribution between body tissues and intravascular compartments.…

Adsorption is the bond of particles, particles, or atoms from a gas, fluid, broken down and attached strongly to a surface. This procedure makes a film of the adsorbate on the surface of the adsorbent. This methodology varies from absorbtion, in which a liquid (the absorbate) pervades or is absorbed by a porous solid. Adsorption is a surface-based procedure while absorption includes the entire volume of the material. The term sorption envelops both methodologies, while desorption is the converse…

Introduction Chromatographic process is a separation technique which has to do with the mass transfer of test sample between a stationary and mobile phase. HPLC (High Performace Liqud Chromatography) is a vast system which involves the use of a mobile and stationary phase to separate materials. The stationary phase is usually a column packed with solids (usually silica gel) while the mobile phase is usually a solvent or a mixture of various solvents. The mobile phase usually, is the carrier of…

CHAPTER-V FORMULATION AND EVALUATION OF LEVODOPA FLOATING TABLETS FORMULATION AND EVALUATION OF LEVODOPA FLOATING TABLETS Several approaches are currently used to retain the dosage form in the stomach. The principle of the floating tablets is simple and practically approach to achieve increased gastric residence time to obtain controlled release floating tablets designed based on the gas generating principle needs a strong floating matrix former. In this regard HPMC K4M,…

4.2.3.5. Antioxidant assays in gastric tissue homogenate 4.2.3.5.1. Catalase activity Catalase activity in the gastric tissue was measured according to the procedures of Sinha (1972). One ml of homogenate solution was taken and mixed with 5 ml of phosphate buffer of pH 7.4. To this 4 ml of 0.2 M H2O2 was added and time noted. Exactly after 180 seconds of adding H2O2, a set of 1ml of reaction mixture from the above was taken and 2 ml dichromate acetic acid was added. It was then kept in a boiling…
