Beryllium, like any other metal ions in serum, can be fractionated into four distinct groups: rigidly bound to metalloproteins; loosely bound to other types of proteins (labile equilibrium); complexed by the so-called low-molecular-weight fraction (LMW); and occurring as free (or hydrated) metal ions [12].
According to both the anterior border of the major psoas muscle and the space between the major psoas muscle and the lumbar quadrate muscle, the major psoas muscle could be fractionated into three equal parts that would be helpful in judging the location of the lumbar plexus.
The crude PEP was fractionated into two fractions, namely PEP-1 and PEP-2.
FIV was fractionated into two peaks but only the large peak of 34 kDa protein (marked as FIV*) showed proteolytic activity (Figure 3A).
PCBs and pesticides were fractionated into two eluates using 5 g silica gel-packed glass columns (10.5 × 300 mm).
Of the 12 PRP procedures done exclusively with the Pascal, five (41.7%) were performed in a single session, and the rest were fractionated into two episodes.
The serum was concentrated and the proteins were fractionated into two major peaks by size exclusion chromatography on a Superdex 75 HiLoad 16/60 column.
The alloy was fractionated into four fractions by temperature-gradient fractionation, and the fractionation was analyzed by 1H NMR, 13C NMR, DSC and WAXD.
Particularly, sample B exhibits better toughness, higher molecular weight and slight lower flexural properties than sample A. Then, these two samples were fractionated into six fractions via temperature rising dissolution fractionation, respectively.
The natural organic matter (NOM) from the sediment elutriate, which was obtained from a drinking water reservoir in South China, was fractionated into four fractions by using XAD-8 and XAD-4 resin.
