These methods are still accompanied by labor-intensive preparations and remain time consuming.
I don't know how the ancient Aztecs prepared this delicious dish, but these days the labor-intensive preparation is something that many families undertake as a holiday ritual.
The emphasis is on freshness of ingredients and labor-intensive preparation.
On the other hand, primary neuronal culture systems can provide a strong neuronal phenotype, however they may not be suitable for large-scale drug screening for the following reasons, i.e. costly and labor-intensive preparation, variation of culture and cell populations between animals and embryonic tissue usage.
(16) If a large number of CoA species are quantified, this would require labor-intensive preparation of each standard individually.
However, determination of specificities of GBPs required a large amount of the glycans and much labor-intensive preparation prior to the development of glycan microarray technology.
Despite the advantages of cellulose gel permeation chromatography to analyze cellulose molecular weight distributions during enzymatic hydrolysis, only very few studies performed GPC measurements due to a complex and labor intensive sample preparation [ 9, 10].
The MiSeq uses fluorescently tagged terminator chemistry and requires 39 hours for paired-end sequencing but has higher throughput and an associated simpler, less labor intensive library preparation methodology than the PGM.
Conflicting data on efficacy, significant cost, and a labor intensive process of preparation has limited the pace of development of ACI in RCC.
In addition, the labor intensive and time consuming preparation and analysis of the tissue precludes real time feedback to the clinician.
When compared with traditional Sanger sequencing (prepping an equal amount of samples), our method was only slightly more time consuming (i.e., labor intensive), due to the preparation time required for the 454 run (e.g., quantification and normalization of DNA prior to pooling).
