The corresponding simulation studies show broadly similar trends to the lab-based data. For both the perfect match (Pr(D) = 0) and mild dropout (Pr(D) = 0.4) conditions, the median ltLR rapidly reaches the IMP but does not exceed it, while under severe dropout (Pr(D) = 0.8) the median ltLR rises towards the IMP but does not reach it ( Fig. 1, middle). For the low and high rates of uncertain calls, the IMP is approximately reached at a five and eight replicates, respectively ( Fig. 1, right). When the minor contributor provides only 30 pg of DNA (Fig. 2, top left panel), then if Q is the major contributor the ltLR

is very close to the IMP for all numbers of replicates, whereas if Q is the minor contributor Z-VAD-FMK research buy then there remains a substantial gap between ltLR and IMP even at eight replicates. However, even with this very low template, the ltLR exceeds the mixLR beyond five replicates. When the major and minor contributors are reversed, and the amount of DNA from the minor is doubled (Fig. 2, bottom left), then if Q is the minor contributor the ltLR substantially exceeds mixLR from six replicates and rises to within two bans of the IMP at eight replicates. Under both conditions, the two-contributor analysis gives a very similar result to

the one-contributor-with-dropin analysis. When the minor contributor is subject to high dropout (Fig. 2, top right), then if Q is the major contributor the ltLR exceeds the mixLR after one replicate,

and Enzalutamide in vitro rises rapidly to within about 2 bans of the IMP, but the gap narrows only slowly thereafter. The one-contributor-plus-dropin analysis gives an ltLR that is broadly similar to the two contributor analysis, but with a wider range indicating greater variability. If Q is the minor contributor, the median ltLR increases rapidly from a low base, and appears to stabilise after about five replicates, about four bans below the IMP but exceeding the mixLR. The range increases after three replicates, and remains high up to eight replicates. With reduced dropout for the minor contributor (Fig. 2, bottom right), inferring the presence of a major contributor Q is harder because of additional PRKD3 masking by the minor contributor. The median ltLR in both the two contributor and one-contributor-plus-dropin analyses eventually reaches within 2 bans of the IMP, with the latter showing a greater range. Conversely, the lower dropout rate leads to improved inference for a minor contributor Q, with the median ltLR rising to about three bans below the IMP at eight replicates, and exceeding the mixLR from four replicates. Interestingly, after six replicates the range of the minor contributor ltLR overlaps the range for the major contributor. The 30 PCR cycles condition gives the highest ltLR at one replicate but little improvement with additional replicates (Fig. 3, left).
