Molecular Detergents...a brief view..

Molecular Detergent??
Detergents are the cleansing agent, act as surfactants, emulsifying agents used in many biological experiments, and if we add the molecular its only mean those synthetic surfactants or detergent that are generally use in the Biochemical experiments. They are polar compounds with hydrophilic and hydrophobic regions.

How does a surfactant work?
The hydrophobic end that is attracted to oil, grease, and dirt . And the hydrophilic part is attracted to water. The hydrophobic end of the molecule gets away from the water and the hydrophilic end stays next to the water. When dirt or grease is present (hydrophobic in nature) the surfactants surround it and form a small aggregate known as “Micelle” which helps in the dislodging of the grease or dirt from the boundary.

Properties of Detergents…
Detergents generally of have 2 properties… a. CMC ( critical micelle concentration). b. MMW ( micelle molecular weight).

Types….
Depending upon the charge of hydrophilic head group detergents are categorized in four group… •Anionic. •Cationic. •Amphoteric. •Non-ionic.

Influenza A detection by MDCK cell line

By
The influenza A (IA) virus is the principal cause of the outbreaks of flu. A large number of laboratories participate in the worldwide surveillance of influenza virus activity and contribute to the early recognition of newly emerging epidemic strains. Differentiation between influenza A and B viruses and determination of the subtypes of influenza A virus isolates are the first steps in the characterization of influenza viruses. This analysis is traditionally done by hemagglutination inhibition (HI) tests with specific antisera raised in ferrets, chickens, or sheep. The diagnosis of Influenza A is largely clinical. Nevertheless, it is necessary to carry out some form of rapid antigenic diagnosis and the culture of respiratory samples to confirm the etiology of the respiratory disease and to determine the antigenic characteristics of the epidemic strains. Although the “gold standard” isolation technique is inoculation in embryonated hens’ eggs, the technical difficulties involved and t...
