This discovery of Dynabeads revolutionised the liquid-phase kinetic separation of many biological materials. [3] Since being licensed to Dynal in 1980, this magnetic separation technology has been since used for the isolation and manipulation of biological material, including cells, nucleic acids, proteins and pathogenic microorganisms.
Superparamagnetic microbeads: the monosized Dynabeads (scanning electron microscope image)Microbeads, also called Ugelstad particles [1] [2] [3] after the Norwegian chemist, professor John Ugelstad, who invented them in 1977 and patented the method in 1978, [4] are uniform polymer particles, typically 0.5 to 500 microns in diameter.
Immunomagnetic separation (IMS) is a laboratory tool that can efficiently isolate cells out of body fluid or cultured cells.It can also be used as a method of quantifying the pathogenicity of food, blood or feces.
The NFL's concussion protocol is a five-step process that each player diagnosed with a concussion must clear before he can return to gameday action. Here are the five steps, per the NFL:
What I liked about Storyworth. There’s a lot to like about Storyworth, assuming you either choose to answer the questions yourself or choose to pepper a willing participant.
The U.S. Postal Service (USPS) will raise shipping prices in early 2025 while keeping the cost of first-class stamps unchanged. The proposed price hikes, which would take effect Jan. 19, include a ...
SYBR Gold is an intercalator.This means it binds to DNA by insertion of one dye molecule between two planar bases / base pairs of DNA. Single molecule magnetic tweezers assays reveal systematic lengthening and unwinding of DNA by 19.1º ± 0.7º per dye molecule upon binding, consistent with intercalation.
