  • Method for determining oligonucleotide concentration
    Publication number: 20050153297
    Abstract: The invention provides a simple, sensitive method to determine the concentration of oligonucleotides in biological matrices, such as plasma. The method involves obtaining a biological specimen containing a concentration of an oligonucleotide, removing an amount of protein from the sample, subjecting the sample to a chromatographic separation, and analyzing the eluant for the amount of oligonucleotide by mass spectrometry. The assay provides a reliable measure of the concentration of oligonucleotide in the concentration range of about 5 to about 10,000 ng/mL of sample.
