A biphasic liquid preparation containing two immiscible liquids, one of which is dispersed as minute globules into the other, is termed as pharmaceutical emulsion. The liquid in the form of minute globules is the dispersed phase...

The formulation of a suspension possessing optimal physical stability depends on whether the particles in suspension are to be flocculated or to remain deflocculated. First approach involves use of a structured vehicle to keep...
Two important interfacial properties of suspensions are: The surface free energy, and The presence of electric charges on the surface of the dispersed particles. Surface Free Energy When solid or liquid materials are reduced in...
The solid drug is crushed into smaller particles and then dispersed in a dispersion medium in order to prepare a suspension. As a result of crushing, the surface area of particles and their associated surface free energy...
The dispersion system is categorised in the following three groups based on the size of dispersed particles: Molecular Dispersion: This system behaves as true solutions where the solute phase is present in the solvent phase. The...
Industrial fermenter are either of anaerobic or aerobic classes. Anaerobic fermenters do not require much special equipment, except for the removal of heat generated during the fermentation process; on the contrary, aerobic...
E.M. Southern invented the technique of southern blotting. This method is useful in molecular biology. In this method, hybridisation analysis is performed by transferring the DNA from a gel to a membrane. The DNA is cleaved using...
ELISA is a solid-phase enzyme immunobinding assay, and the most essential of the immune-enzyme assays. In this method, the antigen is attached to an antibody anchored on a solid phase (polystyrene or polyvinylchloride). This...
The method of western blot was discovered by George Stark at Stanford, and the name western blot was laid down by W. Neal Burnette. This method, also known as immunoblot or protein blot, detects specific proteins in a sample of...
The desired antibodies should be extracted from a media sample of cultured hybridomas or a sample of ascites fluid. The contaminants in the cell culture sample consists of growth factors, hormones, and transferrins. The in vivo...
