Therefore, the aim of the present study was to evaluate the feasibility of using milling combined with an electrostatic fractionation (ES) of wheat straw (WS) as a way to separate fractions that are enriched in cellulose and more enzymatically accessible, from recalcitrant tissues enriched in lignin-hemicelluloses, in order to produce biofuels.
Previous work using the F ab′ 2 fragment of A5B7 in the same xenograft model system, comparing single administration of antibody with the administration of the same activity as three separate fractions, demonstrated reduced efficacy as a result of fractionation (Pedley et al, 1993).
Secondary uranium stock solutions (1 mL) were added to the resin-packed columns, eluted with multiple bed volumes (3-6) of 4 M HCl collected as separate fractions of ~2 mL, and then eluted with multiple bed volumes (6-10) of 0.1 M HCl collected as separate fractions of ~2 mL.

These aliquots were collected as separate fractions.
While pretreatments like ammonia fiber expansion (AFEX) do not physically extract hemicellulose or lignin as separate fractions, they do modify the cell wall ultra-structure through mechanisms that are currently not well understood [ 4].
As a separate approach aimed at identifying the fraction of positively selected amino acid fixations, we implemented the method of Eyre-Walker and Keightley (2009).
The S-phase fraction was investigated as a separate parameter by flow cytometry.
The crude methanolic extract as well as the TLC separated fractions were tested for antimicrobial activity using four bacterial species (Gram positive bacteria: Bacillus subtilis and Streptococcus faecalis; Gram negative bacteria: Escherichia coli and Staphylococcus aureus), two fungal species (A. flavus and A. niger) and one yeast (C. albicans).
In the World Health Organization classification, cases with classical Burkitt morphologic features and a very high proliferation fraction but without the MYC translocation are not clearly designated as a separate entity and are usually categorized as diffuse large B-cell lymphoma (DLBCL).
He eventually sold it to the University of California for a fraction of its value, with the provision that it be maintained as a separate library.
