We have discovered heterogeneity for both zebrafish PKR, with at least two different alleles differing in four amino acids, and as well as previously for PKZ (nine alleles) [ 19].
7 Positive results from testing with at least two different serologic assays of differing formats and antigen preparations are required to make a serologic diagnosis of infection.
T. versicolor is known to produce at least four different isoenzymes, which can differ significantly in their stability (Koschorreck et al. 2008).
Meanwhile, PEDV is present in the USA in at least three different genomic variants, which differ in pathogenicity [ 12– 12].
It is a Gs coupled receptor with at least four different splice variants that differ in the length of the C termini and in the number of phosphorylation sites, and the above have significant biochemical consequences in the G protein coupling efficiency and the differential susceptibility to desensitization [ 11].
At least three different classes of RNRs that differ in primary sequence, substrate and cofactor requirements have been described in cyanobacteria.
Opinions on how to best score MTF questions differ, as at least six different methods exist to evaluate these types of items (Tsai and Suen, 1993).
This analysis was restricted to the sample of species for which information for at least two individuals differing in radiation level were recorded because within species responses can only be investigated when information for at least two individuals is available.
Next, the PPRL, that is, the proportion of loci with at least two alleles differing in repeat number, was calculated for each bin.
(1) Label retaining studies (Foudi et al., 2009; Qiu et al., 2014; Takizawa et al., 2011; Wilson et al., 2008) conclusively established that the HSC pool comprises at least two compartments differing in their frequency of division.
