Modification to extraction protocols has facilitated procurement of RNA that may be successfully amplified using QRT-PCR.
Modifications to the data extraction form improved reliability.
However, this SILEC technique can be extended to other CoA thioesters by making modifications to the extraction procedure.
Although our analysis was limited to short-chain acyl-CoA species, this approach could be adapted to analyze medium- or long-chain CoA thioesters and other CoA-containing species with appropriate modifications to the extraction protocol.
Total genomic DNA was isolated from either fresh leaves or herbarium specimens using the methods of Allen et al. [ 57] with the following modifications to the extraction buffer: Cetyl trimethylammonium bromide (CTAB) was increased to 3%; and 1% polyvinylpyrrolidone (PVP, w/v, MW 4,000) and 2% beta-mercaptoethanol (Sigma, St . Louis MO) were added.
In order to determine the levels of ochratoxin A (OTA) in cocoa and cocoa products available in Canada, a previously published analytical method, with minor modifications to the extraction and immunoaffinity clean-up and inclusion of an evaporation step, was initially used (Method I).
Modifications to the existing lipid extraction methods and utilisation of sophisticated analytical instruments have increased extraction yields of DHA and EPA.
The initial study of the behavior of PLP and MFCC features for MP3 speech recognition was performed with all previously discussed AM refinement techniques but without any non-standard modifications to the feature extraction process.
Following pilot surveys in both countries, after which further modifications to the data extraction tools were made, trained and supervised teams of field workers visited the selected hospitals and health centres and extracted and recorded facility record data on to the proformas.
The method adopted for estimating the entrapment efficiency was a slight modification to the extraction method followed (Blanco and Alonso 1997).
RNA was isolated from tumor tissue and cDNA was prepared as described previously [ 12], with a slight modification to the extraction step, which used RNeasy MinElute spin columns (Qiagen, Chatsworth, GA, USA).
