Thus, for each low-nitrogen and high-nitrogen sample, a total of 48 aliquots
and 12 blanks were analyzed per day, with two tubes for each treatment.
The prepared aliquots
were analyzed for the presence of formaldehyde and hydrogen peroxide by the guaiacol method; chlorine, hypochlorite, and neutralizers using rosolic acid (method A) and phenolphthalein (method B); Dornic acidity and alizarol (72% v/v) stability tests were also performed as described by Normative Instruction 68/MAPA (BRASIL, 2006).
A 200[micro]l aliquot
of the culture medium was assayed for MDA according to the lipid peroxidation assay kit protocol.
For the Ax-AI the sample was defrosted, two aliquots
of 20 [micro]L were obtained and diluted 1:10.
One portion was serially diluted, spiked into aliquots
of a plasma pool, and then analyzed immediately, avoiding overnight storage of the hemolysate; the other was frozen overnight, then thawed, serially diluted, spiked into plasma samples, and analyzed.
A great majority of all these kinetic studies were carried out with the sample withdrawal method, and aliquots
were analysed with a variety of methods, e.g.
Therefore, the development of a universal method for dividing a clinical specimen into compositionally identical aliquots
is critically important.
Dissolve trypsin at a 1mg/ml concentration in double distilled water and freeze small aliquots
Oxoid Dry-Bags[TM] are ready to use in a matter of minutes and contain sufficient material to make 20 litres (88 aliquots
of 225ml) of medium or diluent.
Its document management capability allows any type of document such as Word consent forms, spreadsheets and image files to be loaded into the LIMS and associated with LIMS objects like samples, aliquots
, clinical subjects and experiments.
The levels of enterolactone in cryopreserved serum aliquots
, obtained from 383 women with palpable cysts at the time of their first cyst aspiration, were measured using a time-resolved fluoroimmunoassay (TR-FIA).
Each of those samples, in turn, will be divided in up to three aliquots
for the purposes of the study.
