For the baculovirus insect cell expression system, a modified pFastBac Dual vector backbone with the melittin secretion signal sequence (Tessier et al. 1991) and an N-terminal HIS-tag encoded downstream of the polyhedrin promoter was used as expression backbone.
Prior to or at the time of randomization, investigators selected an open-label dual NRTI backbone regimen of a fixed-dose combination tablet of either abacavir/lamivudine (ABC/3TC; Epzicom; Kivexa; ViiV Healthcare, Research Triangle Park, North Carolina, USA) or tenofovir/emtricitabine (TDF/FTC; Truvada; Gilead Sciences Inc ., which was administered to participants q.d.
For simplicity, most patients receive Truvada, a coformulated tablet containing tenofovir and emtricitabine as the dual nucleoside cART backbone.
This illustrates the advantage of using a spin-labeled probe that is more rigidly linked to the protein backbone by dual attachment to i, i+3/4 cysteine sites than the more classical method of modifying a single cysteine site with MTSL.
Matrix-fracture transfer functions are the backbone of any dual-porosity or dual-permeability formulation in the modeling of fluid flow in fractured porous media.
In addition, because the expression vector backbone contains a dual promoter system for expression in bacterial and mammalian cells, the final construct can be used directly in cell imaging studies.
This dual relationship, between DNA sequence and backbone behavior on one hand, and backbone behavior and groove dimensions on the other hand, allows to decipher the link between DNA sequence and groove dimensions.
To demonstrate the specificity of the dual reporter in these new vector backbones, the same co-transfection experiments were conducted.
Plasmids used in this study contained a dual luciferase cassette on a yeast vector backbone with the URA3 selectable marker.
Second-line therapy should include the continued use of a dual nucleoside/nucleotide reverse transcriptase inhibitor (NRTI -containing backboNRTI -containingh a change in the non-NRTI component, most often to an ARV backboneg together drug class.
Against my back I felt the dual father through the door almost completely, our air already so tight against my backbone in distraction that I no longer could quite sit up off the child there, not that I would have, or even ever: the absence spilling absent in my moan holes, leaking into what I'd be.
