Increasing concentration of purified his-tagged PTB protein (500 and 800 ng) was incubated with 5 pmoles of in vitro transcribed RNA corresponding to the IRF2 bicistronic RNA (derived from the construct pRIRF2F) and binding reaction was performed in a final volume of 20 µl at 30°C for 20 minutes.
Protein samples derived from the construct were crystallized into two different crystal forms, both of which contained four molecules per asymmetric unit.
The above observations and predictions derived from the constructed host-pathogen interspecies interaction networks allowed us to explore the dynamics and underlying mechanisms by which C. albicans interacts with zebrafish during infection, providing new insights for future experiments in infectious diseases.
Three different types of bias are distinguished, depending on whether the source of interpretation problems derives from the construct, method of the study, or specific items (called construct, method, and item bias or differential item functioning, respectively).
All other NEMO constructs were derived from the NEMOw construct using site-directed mutagenesis (QuikChange XL II mutagenesis kit) and expressed and purified in the same manner.
When 2-month-old hardened transgenic banana plants derived from the three constructs were subjected to Fusarium wilt bioassay using Foc Race 1 cultures, marked Fusarium wilt symptoms were seen in untransformed banana plants at 4 weeks from inoculation.
Int* helper plasmids were derived from the expression constructs (see above) by deleting the attB site and mini-white marker and replacing the SV40 terminator with the 3′ UTR of the germline-expressed bag of marbles gene.
For untransformed control plants and each of the transgenic lines derived from the three constructs, a minimum of four replicates were screened for Foc Race 1 infection and the assays were repeated four times.
Among the three groups of transgenic plants derived from the three constructs, plants derived from p1301- MusaBAG1 were generally healthy with no clear symptoms of Fusarium wilt barring a few lines where we could see mild to moderate symptoms (Fig. 4).
While the intensities of the latter bands were much higher in reticulocyte lysates programmed with constructs containing F2As of 30, 25, 24 and 23aa (in comparison with F2As of 22-18aa), translationtion products derived from the four constructs encoding shorter 2A sequences were mostly uncleaved.
