After 24 h, triplicates of subconfluent cells were treated with four different concentrations (1, 5, 10 and 50 ng ml−1) of activated rhTGF- β2 protein (R&D Systems, Minneapolis, MN, USA) and incubated for 72 h.
NG was activated by CYP2A13 and CYP2A6, the genotoxicity of NG being much lower than that of NMPA or NMPN.
Treatment with rTGF- β1 (5 ng ml−1) significantly activated the phosphorylation of Smad2 and production of Smad4 in HuCCT-1 cells, as evaluated by western blotting analysis.
There are two ways of activating NMDARs.
Cells were then washed free of activating agent and thereafter maintained in 20 ng/mL IL-2 and used for experimental purposes 4 5 days later.
Transfection with 2ng or 5 ng of CTNNB1/β-catenin plasmid alone activated the TCF reporter by 2-fold and 5.3-fold, respectively (Fig. 4A, left panel).
Similarly, the detection threshold for the well-characterized octenol receptor located on the maxillary palps of Cx. quinquefasciatus is 0.1 ng [38] while 10,000 ng of DEET (5 log steps difference) activates an antennal OSN in the same insect [5].
293T cells transfected with TLR4 were activated by the supernatant that induced an activation of TLR4 similar to the one obtained with 40 ng of LPS (figure 4).
Thermolysin-activate hK7 (25 ng) was then added to 100 ng of either recombinant Dsg1 or Dsg2 (R&D Systems).
Use 200 ng of gel purified PCR DNA (in no more than ∼5 µL) and mix with a 100 µL aliquots of the λ Red activated SW105+fosmid.
