Virus Structure & a quick glance into Virus Biology

virus structure

Virus are the smallest and ultra microscopic particles discovered by Iwanowsky in 1892. They are observed only by an electron microscope. They are so smaller that they can pass through bacterial filters. Further, they are obligate parasites on either animal or plant cells. That means they are inactive viable forms only inside the host and inactive once outside […]

HPLCPumps: 3 Types and their Function

Hplc Pumps

HPLC pumps from the basic part of HPLC instrumentation. Unlike other chromatography techniques, HPLC needs to generate pressure by pumps. Without a proper pump, HPLC analysis is impossible and the instrument is not operable. As the name, HPLC i.e. high-performance liquid chromatography indicates, one needs to generate pressure. HPLC pumps generate pressure on the solvent so […]

Stem Cell Bank: Their uses and types

stem cell bank

Stem cells are a great promise to sustain the health risks in future. Recent studies proved them to be capable to transform into even desired organs like eyes and liver by some Japanese scientists. On injection of stem cells, they were shown to replace the dead tissue in the heart muscles in the patients with myocardial infarction […]
