An example Gel documentation system, showing the results of gel electrophoresis on a connected monitor.. A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels.
Agarose gel has large pore size and good gel strength, making it suitable as an anticonvection medium for the electrophoresis of DNA and large protein molecules. The pore size of a 1% gel has been estimated from 100 nm to 200–500 nm, [4] [5] and its gel strength allows gels as dilute as 0.15% to form a slab for gel electrophoresis. [6]
This occurs in a region of the gel that has larger pores so that the gel matrix does not retard the migration during the focusing or "stacking" event. [10] [11] Separation of the proteins by size is achieved in the lower, "resolving" region of the gel. The resolving gel typically has a much smaller pore size, which leads to a sieving effect ...
Gel permeation chromatography (GPC) [1] is a type of size-exclusion chromatography (SEC), that separates high molecular weight or colloidal analytes on the basis of size or diameter, typically in organic solvents. The technique is often used for the analysis of polymers.
[3] and the mobility of larger circular DNA may be more strongly affected than linear DNA by the pore size of the gel. [4] Separation of very large DNA fragments requires pulse field gel electrophoresis (PFGE). In field inversion gel electrophoresis (FIGE, a kind of PFGE), it is possible to have "band inversion" - where large molecules may move ...
The routine physical, also known as general medical examination, periodic health evaluation, annual physical, comprehensive medical exam, general health check, preventive health examination, medical check-up, or simply medical, is a physical examination performed on an asymptomatic patient for medical screening purposes.
On 24 March 2010, Hong Kong's Department of Health recalled both Po Chai Pills Capsule Form and Po Chai Pills Bottle Form from local retail outlets and consumers. [ 2 ] On 11 May 2010, a licensed manufacturer in proprietary Chinese medicine, Li Chung Shing Tong (Holdings) Ltd. HK was given the green light to resume production and marketing of ...
Oral glucose gel is an over-the-counter medication, consisting primarily of dextrose and water, along with small amounts of other compounds. It is frequently used by people with diabetes and those with hypoglycaemia to raise their blood glucose when it becomes dangerously low.
