Technology
Gel permeation or sieve chromatography that is performed on porous gels that separate solutes on the basis of size. Smaller solutes are included within the particles of the gel matrix more frequently than larger solutes, thus affecting elution rates.
Technology
A quantum optical-electrical phenomena consisting of an alteration in light reflectance as a result of binding of molecules to a surface from which total internal reflection is occurring. Used to detect macromolecular interactions, SPR can be used as the basis for a sensor which is capable of sensitive and quantitative measurement of a broad spectrum of chemical and biological entities.
Technology
A laboratory procedure in which proteins are first separated across a gel, usually polyacrylamide, according to their isoelectric point, and then separated in a perpendicular direction on the basis of their molecular weight.
