  • Polyanion for improved nucleic acid amplification
    Patent number: 7910720
    Abstract: The present invention is directed to a novel chemical compound comprising the structure [Xx-(CH2)m-phosphate-Yy]n, characterized in that 3?m?6, 30?n?60, each x and y is independently from each other 0 or 1, each X and Y is independently from each other any photometrically measurable entity; provided that the terminal X can also be an —OH group or a phosphate group, and further provided that the terminal Y can also be an —OH group. Such a compound can be used as a suitable hot start additive for PCR based amplification of nucleic acids.
