Microfluid extraction method

摘要

Isolating target molecules (I) from a sample using a receptor array on a microfluidics carrier, is new. Isolating target molecules (I) from a sample comprises: (a) preparing a microfluidics carrier having an array of many different receptors, at separate positions; (b) passing a sample containing (I) through the carrier so that (I) can bind specifically to its immobilized receptor; (c) removal of non-bound sample material from the carrier; and (d) elution of bound (I). Independent claims are also included for: (1) a similar method in which interferants are bound to the receptors and unbound (I) are eluted; and (2) isolating target molecules comprising at least one cycle of the new method and at least one cycle of the method of (1).
