ABSTRACT:
A novel method for inactivating undesirable members in a nucleic acid sample which comprises undesirable and desirable members of a nucleic acid family. The method includes the step of adding a blocker to the sample which selectively associates with the undesirable members such that they are unable to participate in any further processing of the sample. The method advantageously provides a means whereby desirable members of the nucleic acid family can be processed, i.e. identified, amplified and/or isolated, without interference from undesirable sequence-related members.
