    Thermal shock is crucial for successful PCR amplification from fungal spores. A. fumigatus spores at three different concentrations (8 × 10 8 /ml, 1 × 10 8 /ml, and 5 × 10 7 /ml) were prepared as described in Basic Protocol 1 . 3 µl of spore suspension were used as the DNA template for PCR. ( A ) PCR result from spore suspension subjected to thermal shock of 95°C for 15 min and −80°C for 10 min prior to PCR, as described in Basic Protocol 2 . No thermal shock was done for spore suspensions from Panels B and C . Subsequently, a PCR was run with an initial denaturation step of 95°C for 1 min (A), 5 min (B), or 15 min (C) with primers ITS1 and D2 (expected PCR product ∼1.2 kb) and LongAmp Taq DNA polymerase with PCR conditions described in Basic Protocol 2 . P: positive PCR control amplified from genomic DNA (50 ng) of the A. fumigatus wild‐type strain; N: negative control (no DNA).

    ssDNA production by aPCR. ( a ) aPCR reactions were assembled with a 50-molar excess of a forward primer for the amplification of a 1,000 nt ssDNA fragment using the M13mp18 ssDNA plasmid as template, and with 10 different polymerases that were tested for highest yield of ssDNA production (upper band: expected dsDNA size is 1,000 bp; lower band: expected ssDNA size is 1,000 nt) as judged by agarose gel electrophoresis (right panel).

Agarose gel electrophoresis of the digestion products as labeled by lane (right panel). M: Marker, C: aPCR product control, ExoI: exonuclease I, S1: S1 nuclease, Enz: Eco RI + Nae I. ( c ) NEB LongAmp was used to generate ssDNA up to 15,000 nt long using lambda phage dsDNA as template. Purification of the 10 kb fragment shows a single band of higher molecular weight than the M13mp18 ssDNA (7,249 nt). ( d ) The primer design algorithm aPrime was used to select primers for product sizes between 500 and 3,000 nt using M13mp18 ssDNA as template and the Quantabio Accustart HiFi enzyme. SYBR Safe stained agarose gels illuminated under blue light show dsDNA as yellow bands, while ssDNA show as orange bands.
