Parkinson's is a disease which affects the brain, causing problems with movement. The muscles become stiff and sometimes shake, and the person moves more slowly than normal. Parkinson's and dementia are linked because, in some people with Parkinson's disease, dementia may occur as the illness progresses. Dementia is a disorder in which brain function deteriorates, leading to difficulties with remembering, planning and organizing, recognizing people and things, and communicating with others.
Thermo rolls out predictive liver toxicity assay. By Gareth Macdonald Gareth Macdonald, 08-Mar-2011 2011-03-08T00:00:00Z. Thermo Fisher Scientific has launched a predictive assay that, it claims, can assess a drug candidateâs potential to cause liver damage earlier than traditional methods.
Gel Retardation Assay (Molecular Biology). The gel retardation assay, also known as the bandshift assay or electrophoretic mobility shift assay (EMSA), is used to detect DNA-binding proteins in crude cell extracts and to study the binding activity of purified DNA-binding proteins. It is also applicable to the study of RNA-protein interactions. The basis of the assay is that protein-DNA complexes remain intact when gently fractionated by gel electrophoresis and migrate as distinct bands more slowly than the free DNA fragment.
