32Dcl3 cells were washed free of IL-3 and resuspended in IL-3-free medium.
For half-life assessments made in G-CSF, cells were washed free of IL-3 and incubated in G-CSF for 18 hours.
In order to derive a global list of candidate IL-3 targets, we conducted kinetic microarrays [30] in which 32Dcl3 cells were washed free of IL-3, exposed to actinomycin D to stop transcription and then treated with either IL-3-replete or IL-3-deficient medium (Supplemental Figure S1).
We conclude that activated caspase-1 functions in apoptosis, but not pyroptosis, because (i) the percentage of TUNEL+ cells was significantly decreased (18±3.6% reduction) by the caspase-1-specific inhibitor YVAD-CHO and (ii) the cultures/xenografts were free of IL-1 β or IL-18 although they expressed the respective pro-cytokines (shown in Figure 4d for IL-1 β).
With this protocol, we obtained bulk numbers of Th1 and Th17 cells largely free of contaminating IL-17 and IFN-γ producing cells in Th1 and Th17 polarizations, respectively (Figure 1).
These results showed that acidic conditions (pH 3.5) were able to modify interactions between IL-13, binding proteins, and assay antibodies, so that the total (bound and free) concentration of IL-13 was measured.
Total IL-1β (i.e., sum of free IL-1β and canakinumab-IL-1β complex) was detected with a limit of detection of 0.1 pg/ml in human serum.
A series of ammonium-diol and -triol ionic liquid (IL) monomers were synthesized and used in step-growth polymerization with the commercial di-isocyanate monomer, toluene-di-isocyanate (TDI), in the presence of free ammonium IL to form new curable ammonium-based polymerized ionic liquid/ionic liquid (PIL/IL) composite film coatings.
The composite membranes of the PILs containing different polycations and 10 wt% of free ionic liquid (IL) with similar structures to each PIL monomeric unit have CO2 permeabilities between 3.66 and 20.4 Barrer, while they exhibit permselectivities ranging from 28.3 to 43.0 for CO2/CH4 and from 25.8 to 34.7 for CO2/N2.
This difference arises due to the immense disparity between the levels of free IL-6 (order of 10 pg/ml ≈ 10−4 nmol/l) and free sIL-6Rα (order of 100 ng/ml ≈ 1 nmol/l) in circulation.
The results show that with a low degree of cross-linking, a high ionic conductivity of 2.6 mS/cm can be achieved, which is mainly due to the presence of a significant amount of free ILs in the interpenetrating pores of the mats.
