    Summary

    A new, faster method accurately genotypes the tp53 M214K zebrafish mutant. This high-resolution melting analysis protocol streamlines research for modeling human diseases.

    Area of Science:

    • Genetics and Zebrafish Models
    • Molecular Biology Techniques

    Background:

    • The tp53 M214K zebrafish mutant is valuable for modeling human diseases.
    • Current genotyping methods are time-consuming, involving restriction digests and Sanger sequencing.

    Approach:

    • Developed a robust genotyping protocol using high-resolution melting analysis (HRMA).
    • Implemented a parallel, in-tandem wildtype spike-in approach for accurate zygosity discrimination.
    • Detailed the HRMA-based method for tp53 M214K genotyping.

    Key Points:

    • HRMA offers a faster and more reliable alternative to conventional genotyping.
    • The protocol effectively distinguishes tp53 M214K zygosity.
    • This method reduces turnaround time for researchers.
