Oligonucleotide sizing using immobilized cleavable primers

The present invention provides modified oligonucleotide primers that (i) are designed for attachment to a solid support in a manner that does not block the ability to extend the primer from its 3' end, and (ii) incorporate a clearable moiety so that a 3' portion of the primer (linked to an...

More Information
Summary:The present invention provides modified oligonucleotide primers that (i) are designed for attachment to a solid support in a manner that does not block the ability to extend the primer from its 3' end, and (ii) incorporate a clearable moiety so that a 3' portion of the primer (linked to an extension product) can be released from an immobilized 5' portion. Upon selective cleavage of the cleavable site, a large portion of the primer fragment remains affixed to the solid support. This enables the release of primer extension products that contain about five or fewer base pairs of the primer sequence, to provide more useful sizing and sequence information per fragment than extension products containing the entire primer.
