| 摘要 |
The invention relates to a method for transferring a substance immobilised to microparticles from a first vessel to a second vessel, wherein the microparticles are of magnetic or magnetisable material or the microparticles are attached to a magnetic or magnetisable body and the microparticles, to which the substance is immobilised, are captured with the aid of a magnet submerged in the first vessel, the magnet along with the microparticles captured thereupon is transferred to the second vessel and the microparticles are released from the magnet's influence, wherein the magnet's surface is separated from the microparticles either by a membrane or magnet's coating so that the membrane or coating pressing tightly against the magnet's surface separates the magnet from the microparticles but does not substantially weaken the magnetic field directed at the microparticles wherein the substance is an enzyme. |
