The parent botanical was fractionated for evaluation of potential active components.
We determine how, for a fixed total electron-budget, the available dose should be fractionated for maximum strain mapping precision.
Similarly, differentiated cells can be fractionated for further investigation based upon the lineage restricted expression of specific miRNAs.
At this time blood samples were taken for a head-space analysis (whole blood); additional serum and hemoglobin were fractionated (for details see below).
At 24 h after LPS, lungs were extracted from mice, and nuclear proteins were fractionated for western blot analysis of nuclear Nrf2, indicative of activated Nrf2 [ 11].
Cells were fractionated for neutrophils and monocytes using a XE-2100 automated hematology analyzer (Sysmex, Kobe, Japan) in the central laboratory of the hospital.
Extracts were fractionated for 3 h 30 min at 35,000 rpm at 4°C in a Beckman SW41 rotor, and the gradients were recovered in 3 fractions [monosome, light polysome (2 to 5 ribosomes) and heavy polysome (> 5 ribosomes)] using a Brandel gradient fractionator equipped with an ISCO UA-6 flow cell set to 254 nm.
Particularly useful for this purpose are fractionated factorial designs, requiring only a fraction of all possible combinations of a full factorial design.
Upon reaching 80% confluency, cells were starved overnight and treated the next day with 50 ng/ml FGF19 and 1 µg/ml heparin for 10 min prior to the addition of 10 ng/ml TNFα for 30 min. Cell lysates were fractionated as for EMSA.
Cells were collected and lysed in extraction buffer (Sigma-Aldrich, E1156), then the samples were centrifuged at 1000× g for 10 min and then at 2000× g for 20 min. The supernatant, containing the crude migrasome fraction, was fractionated at 150000× g for 4 h in a multi-step optiprep dilution gradient.
