Laboratory study demonstrates uniform whole genome amplification from minimal human DNA samples, highlighting broad utility for clinical diagnostics and forensics.

Key Points

To develop and evaluate multiple displacement amplification (MDA) as an isothermal method for whole-genome amplification yielding high-coverage, high-molecular-weight human genomic DNA.
Engineered multiple displacement amplification (MDA), an isothermal, strand-displacing reaction applied directly to purified DNA (1–10 copies), crude whole blood, and cultured tissue cells.
Evaluated amplification representation, yield, and product length across eight chromosomal loci compared to PCR-based methods.
Validated amplified products across downstream applications, including SNP genotyping, chromosome painting, Southern blotting, RFLP analysis, subcloning, and sequencing.
Yielded 20–30 µg of DNA product with an average length exceeding 10 kb from starting amounts as low as 1–10 copies of human genomic DNA.
Demonstrated an amplification bias of less than 3-fold across eight chromosomal loci, compared to 4–6 orders of magnitude observed with degenerate PCR-based techniques.
