Yet, by performing the assay in duplicate up to 16 samples could be incorporated into the 96 well microtiter format.
It is now generally accepted that we and all other jawed vertebrates are the product of a remarkable two rounds of WGD, known as 2R [ 2], which duplicated every gene up to four-fold (fish and frog genomes have undergone a third duplication more recently).
We raised a total of 120 Cobb-500 broiler chicks in duplicate trials up to 3 weeks to determine the effect of BPE on the reduction of colonization using a C. jejuni RM1221 marker strain in broiler cecum.
In a separate experiment, we also raised a total of 200 Cobb-500 broilers in duplicate trials up to 6 weeks to investigate natural colonization of Campylobacter in presence of BPE and observed that 1.0 g GAE/L of BPE reduced natural colonization level of Campylobacter by 2 logs in broiler cecum as a water supplement.
Classes alpha and mu, which use a tyrosine in the active site, present the higher number of successful duplicates, with up to seven isoforms per species.
Given that duplicates make up to 80% of eukaryotic genomes, the small contribution is surprising and points to dominant roles of other buffering processes, such as alternative metabolic pathways.
Given that duplicates make up to 80% of eukaryotic genomes, the small contribution is surprising and points to dominant roles of other buffering processes, such as rerouting metabolic flux (see ref. [ 9] for an example).
Additionally, those genes with duplicates in up to three species can be regarded as single copy genes, thus the number of shared single copy genes may be higher than the species-specific single copy genes.
Similar scenarios take place for whole genome duplication (WGD), where gene duplicates can tolerate up to 10 times more amino acid changes than old duplicates in vertebrates [ 43, 44].
Figure 2b shows that accounting for the UMIs reduced the median duplicate rate from 43.7%to1.21.2 % with a few libraries showing a higher duplicate rate of up to 7%%.
