US Patent:

8273863, Sep 25, 2012

Filed:

Jul 11, 2000

Appl. No.:

09/613903

Inventors:

Heather J. Jordan - Gaithersburg MD, US

Assignee:

Life Technologies Corporation - Carlsbad CA

International Classification:

C07H 21/04
C12Q 1/68

US Classification:

536 231, 435 61

Abstract:

The present invention provides nucleic acid compositions or ladders which may be used as standards for estimating the size (in base pairs) and or mass of nucleic acid molecules of unknown size and/or mass. The invention also relates to methods for producing such compositions or ladders, ladders or compositions produced by such methods, and to methods for estimating the size and/or mass of nucleic acid molecules by comparison to these nucleic acid sizing ladders.

Filed:

Dec 23, 1999

Appl. No.:

09/472067

Inventors:

A-Li Hu - Kensington MD, US
James Hartley - Frederick MD, US
Heather Jordan - Gaithersburg MD, US

International Classification:

C12Q001/68
C07H021/04

US Classification:

435/006000, 536/023100

Abstract:

The present invention provides nucleic acid molecules which may be used as standards for estimating the size (in base pairs) and mass of linear, double-stranded or single-stranded nucleic acid molecules separated by size. The nucleic acid molecules of the invention may be DNA molecules, RNA molecules or DNA/RNA hybrid molecules, and may be double-stranded or single-stranded. The invention also provides methods for producing nucleic acid sizing ladders from these nucleic acid molecules, ladders produced by such methods, and methods for estimating the size and mass of nucleic acid molecules by comparison to these nucleic acid sizing ladders.
