Title:
流体内の関連する物質の存在及び濃度の双方又はいずれか一方を決定する方法
Document Type and Number:
Japanese Patent JP2008503714
Kind Code:
A
Abstract:
Magnetic particles coated with specific antibodies for substances of interest are introduced into a fluid sample. Over time and with agitation, the magnetic particles become attached to the substance of interest within the fluid. The fluid is then introduced to a magnetic field gradient provided between two magnets ( 1, 5 ). the resultant change to the magnetic filed between the magnets ( 1, 5 ) is determine by a Hall Effect device ( 3 ) or a plurality of Hall Effect devices ( 3 ). This enables the presence and/or concentration of the substance of interest in the sample to be determined.
