Sentence examples for transformation frequency data from inspiring English sources
We could not accurately assess the BIR frequency of the pif1 -m2 mutant using the plasmid-based assay due to more efficient telomere healing at the telomere-seed sequence of the linear CFV leading to an artificially high transformation frequency (data not shown) (Schulz and Zakian 1994).
A linear model was fitted with the lm function after a log transformation of the HGT frequency data using the log function of the base package of R 2.14.2 (Ihaka and Gentleman 1996).
The standardised postprocessing protocol consisted of water reference processing, Hanning filtering (center 0 ms, width 512 ms), zero filling from 512 data points to 1024 data points, Fourier transformation, frequency shift correction, sixth order polynomial baseline correction, phase correction and frequency domain curve fitting.
Fast Fourier transformation data processing of resonance frequency data resulted in determination of a maximum resonance frequency values allowing calculation of implant stability quotient (ISQ) values using the Osstell algorithm.
Log transformations, possibly more appropriate with MN frequency data, were not possible because individual data were not available.
However, our genomic analysis reveals no homologs of comQXPA genes in the P. polymyxa genomes, which may explain the low transformation frequency of CR1 compared to B. subtilis (our unpublished data).
In our laboratory, NCIB3610 typically has a transformation frequency approximately 0.5 1% that of 168 using chromosomal DNA as donor DNA (data not shown) and SMM as the growth medium.
Based on 5 independent transformation experiments, the transformation frequency was calculated as 3.7 × 10-7 (± 14%) transformants per cell.
Frequency Data (National Grid, 2014 2016); http://www2.nationalgrid.com/Enhanced-Frequency-Response.aspx.aspx
The plant transformation frequency from callus tissues was about 48%.
Transformation and analysis of the relative transformation frequency were performed as in reference [27].
