By conjugating a monoclonal IgM antibody of CD8-specificity to magnetite-containing polymer particles, we have developed a rapid and simple one-step procedure for positive selection of T8 cells. The method ensured good yield and viability of pure T8

Kinetic experiments with homodisperse seeds of various particle size verified the previous results as to the effect of particle number, degree of conversion, and initiator concentration on the rate of polymerization. Also, experiments with mixed seed

The swelling capacity of aqueous dispersions of particles (or droplets) containing a relatively low molecular weight, highly water-insoluble compound (Y) may be more than a thousand times higher than that of particles consisting of polymer only. The

Three different types of 15μm macroporous polymer particles (MP) based on poly(styrene- co -divinylbenzene), all with an extreme degree of monodispersity, were prepared by the method of ‘activated swelling’. The type and relative content of low

Poly(vinyl chloride) latexes have been prepared by polymerization in micron and submicron sized monomer droplets. Monomer emulsions with excellent long time stability were obtained by diffusional swelling of vinyl chloride monomer into preformed, sta

Expressions for calculating the stationary state distribution of radicals in compartmentalized systems with a constant number of reaction loci containing an oil-soluble initiator are given. Besides pairwise formation of radicals in the particles, des

The method of activated swelling of polymer particles developed by the authors allows the preparation of monodisperse spherical beads of predictable size from 1 to 100 microns in diameter. The polymer particles may be prepared from a number of differ
