In a model of T1D, expression levels were evaluated in human islet preparations, representing the target organ, as well as in human lymphocytes representing the effector cells in T1D.
Measurements of cilia length in DiffQuik-stained cells in cytospin preparations represented an assessment of the average length of the tuft of cilia at the apical end of each epithelial cell.
Despite attempts to generate pure length-defined heparin oligosaccharides, chromatographic preparations represent a heterogeneously sulfated population of oligosaccharides, thus obscuring the critical structural features of HS/heparin required to inhibit different angiogenic cytokines.
Note, that although we don't know where and how these disulfide bonds are generated, we have at this point successfully generated tetramers from HLA preparations representing 14 different HLA alleles, and in no case have we failed.
Once expression and purification was established we checked whether the large scale preparations represent also catalytically active enzyme.
In the above studies, the brain samples interrogated consisted of "bulk" brain tissue preparations representing cellularly heterogeneous mixes of neuronal and non-neuronal cell types.
In 2002, AHL's PRRSV ELISA was modified to include two recombinant protein preparations representing United States and European strains, but equivalent test performance and cut-off were maintained.
Native tissue preparations represent a model in which individual cells are in histo-anatomical conditions close to the in situ setting, but where targeted intervention and observation at the cell-level are more difficult.
Hybridization probes were made from 18 total RNA preparations representing two biological replicates of the leaves of F1 21/66, F1 22/73 and Teroldego inoculated with P. viticola and collected at 12 and 96 hpi, or sprayed with water (C).
Career preparation represents a major developmental task of adolescence, which has not received sufficient attention in empirical research on career development.
