Method for sizing nucleic acid repeat regions using electrophoresis
The granted patent (Publication Number: US11913068B2) discloses a method for sizing a repeat region of a nucleic acid. The method involves providing a nucleic acid sample, amplifying a nucleic acid with a repeat region, performing capillary electrophoresis to obtain a ladder of amplification products, and generating an internal sizing standard. This standard is created by identifying repeat profiles, generating repeat peak locations, and estimating a linear relationship between peak location and fragment size. The repeat region is sized using this internal standard along with an external sizing standard, which is generated by identifying peaks in the ladder of amplification products and combining linear and non-linear relationships.
Furthermore, the method includes mobility-corrected sizing standards, iterative re-estimation of peak locations, and piecewise scaling of the background model. It also involves determining gene-specific peak locations in the repeat profile based on dynamic thresholds and amplitude criteria. The method aims to provide an accurate and reliable way to size repeat regions of nucleic acids, offering a comprehensive approach that combines internal and external sizing standards, iterative processes, and gene-specific peak identification for enhanced accuracy and efficiency in nucleic acid analysis.
