There are three steps involved in the magnetic separation process: Bind – Microbeads bind to the desired target, relative to the specific affinity of the ligand on the surface of the beads. Wash – Microbeads will move to the side of the tube in response to a magnetic field, along with the bound material. This happens quickly and efficiently ...
A microbead imaged using scanning electron microscopy. Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension [4] when they are first created, and are typically created using material such as polyethylene (PE), polyethylene terephthalate (PET), nylon (PA), polypropylene (PP), and polymethyl methacrylate (PMMA).

Dynabeads were developed after John Ugelstad managed to create uniform polystyrene spherical beads (defined as microbeads) of exactly the same size, [1] [2] at the University of Trondheim, Norway in 1976, something otherwise only achieved by NASA [3] in the weightless conditions of SkyLab. Dynabeads are typically 1 to 5 micrometers in diameter.
Cell sorting is the process through which a particular cell type is separated from others contained in a sample on the basis of its physical or biological properties, such as size, morphological parameters, viability and both extracellular and intracellular protein expression. The homogeneous cell population obtained after sorting can be used ...
Immunoprecipitation (IP) is the technique of precipitating a protein antigen out of solution using an antibody that specifically binds to that particular protein. This process can be used to isolate and concentrate a particular protein from a sample containing many thousands of different proteins.
ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)
B-tagging, the identification of bottom quarks, is the most important example. B-tagging relies on the bottom quark being the heaviest quark involved in a hadronic decay (tops are heavier, but to have a top in a decay, it is necessary to produce some heavier particle to have a subsequent decay into a top). This implies that the bottom quark has ...
High sphericity of polyethylene microspheres, as well as availability of colored and fluorescent microspheres, makes them highly desirable for flow visualization and fluid flow analysis, microscopy techniques, health sciences, process troubleshooting and numerous research applications. Charged polyethylene microspheres are also used in ...
