Sentence examples for samples require the from inspiring English sources

Reliable comparisons of gene expression between samples require the normalization of input amounts, reverse transcription and amplification reaction efficiencies.

While ascorbate is a suitable reductant for homogeneous PMO preparations, fermentation samples require the specific electron donor CDH.

However, some applications, such as the detection of heteroplasmic mutations in mtDNAs, or mutations in pooled DNA samples, require the identification of LLMs, that are present in frequencies well below what is typically sequenced in NGS studies (i.e. heterozygous or homozygous mutations) (Li and Stoneking 2012).

Groundwater samples required the presence of sterile chalk in a ratio of at least 1 13 to promote isoproturon degradation.

The use of DMSO in the sequencing mix as suggested by Royal Botanic Gardens, Kew, UK [36] was helpful in some cases, but several samples required the use of dGTP BigDye Terminator (Applied Biosystems, Foster City, CA) sequencing mix.

The preparation of biological samples requires the application of an acid to precipitate proteins.

The quantification of gene expression in tissue samples requires the use of reference genes to normalise transcript numbers between different samples.

Higher extraction recovery from AFB1 polluted real samples requires the extract solution to contain a certain concentration of methanol because of the hydrophobic property of AFB1.

Although these tools will give useful estimates of the numbers of samples required, the limiting factor is often the availability of suitable control samples, even in the case of verification, which requires less-stringent analysis and therefore fewer samples.

However, (18) is not an usual distribution, therefore its sampling requires the use of a rejection sampling method, such as the Metropolis-Hastings algorithm [32].

Among these, headspace solid phase microextraction (HS-SPME) allows for the rapid fingerprinting of a plant's headspace [7 10], and HS sampling requires the optimization of the extraction parameters to be carried out.
