The phrase "performed upstream" is correct and usable in written English.
It can be used to describe an action taken in preparation for, or to facilitate, a later action. For example, "Prior to launching the new website, a number of tests were performed upstream to ensure that it would function properly."
The control of the amount of the active substances is performed upstream, in the liquid phase.
Moreover, sensitivity analysis techniques are performed upstream to determine the hierarchization of the model parameters and to reduce the dimension of the input space.
The results of the caging experiments performed upstream and downstream of the WWTP Langwiese showed no evidence of estrogenic disruption in males, neither before nor after the upgrade (Fig. 5).
We also extracted transcription factor genes (Table S5) according to identified PWMs (underlined in Table S4) and performed upstream network analysis with transcription factor sets (see below).
CCL carried out hybridizations and performed upstream data analysis.
After baseline measurements, targeted occlusion of the arteriole of interest was performed upstream of cortical penetration.
This is accomplished by performing upstream type inference, which is maximally permissive.
The planktotrophic larvae have a circumoral ciliary band (neotroch) of a unique structure and function: the band consists of monociliary cells performing upstream-collecting of particles based on ciliary reversal [ 117].
However, RT-PCR performed with upstream primers revealed the accumulation of an unspliced transcript in both pbrp2 lines that probably results from a splicing defect due to the T-DNA insertion (Figure 4B; primers a b).
In order to clarify the relationship between Smad1 and ΔFosB/JunD heterodimer, V5-tagged ΔFosB, Flag-tagged JunD and Myc-tagged Smad1 were co-transfected into mPOBs and DNA precipitation assay was performed using upstream AP-1 probe (Probe 1) or SBE probe (Probe 3).
RT-PCR to detect transgene transcripts was performed using upstream (U) 5'-CGGGGTACCTTCCAAGTATTTCTTTTTTTTTGGC-3' and downstream (D) 5'-GTGTTGAGGGAGTCTGGGCAGTCCGT-3' forward primers in combination with the 32P-5' end-labeled (using T4 polynucleotide kinase and γ-32P-ATP) reverse primer (TGrev) 5'-TCATTCCTCGTGTCGATCATGGCCCAGCT-3'.
