Therefore, the time between tissue extraction and freezing (cold ischemia time) must be recorded and made available to investigators requesting tissues for research.
In most cases, the extracts were prepared by hot and cold extraction methods, that is, Soxhlet and percolation techniques, respectively.
The heat and cold extraction methods were used in the preparation of extracts from the prepared sample.
The natural sensitizers are extracted using a cold extraction and the Soxhlet extraction methods.
The paper was characterised in terms of variables such as molecular weight, DP, pH, fibre furnish and other properties, using traditional analytical techniques, such as viscometry for DP and cold extraction for pH [19].
These methods of preparation mimic cold and hot water extract and hence cold and hot water extractions were used in the study in the investigation of anti-inflammatory activity of the mushroom.
Intracellular metabolites were prepared by leakage-free quenching and cold methanol extraction (Hasunuma et al. 2011).
To build the models, 70 spectra of samples with pH values measured using cold extraction, and 60 spectra of samples with DP determined using viscometry were measured using the PHAZIR hand-held spectrometer.
The identification of differentially expressed proteins was impeded by a residual proteolytic activity, since several spots were identified as cleavage fragments of proteins (see below), despite of the use of protease inhibitors for protein extraction and the preparation at cold temperatures.
This procedure was used with all extracts (roots, stems and leaves) obtained with ethanol and hot- and cold-water extraction, and the allantoic fluid harvests were subjected to HA titration.
