The phrase "as initial proof" is correct and usable in written English.
It can be used when referring to something that serves as the first evidence or demonstration of a claim or argument.
Example: "The data collected from the first trial serves as initial proof of the hypothesis."
Alternatives: "as preliminary evidence" or "as first evidence".
As an initial proof of concept, biotinylated lysozyme (biotin-HEL) was used as a model analyte, giving a detection limit as low as 0.1 ng/mL.
Samples from AD patients, normal controls, and in some cases from patients with other diseases were analyzed, which led to the identification of distinct biomarker sets specific to each sample group and thus served as an initial proof of principle.
In the context of a pilot study, this comprehensive scan of the keloid methylome was attempted as an initial proof of concept to generate a knowledge base for insight into the biological complexity of keloids from a genome-wide promoter methylation perspective.
I applaud the work of Charyeva and colleagues as a sound initial "proof of concept," but we must have more robust discussion on how to fully implement task sharing across contexts from all who share similar results.
While Mr. Marquardt defended his conduct on the bench, he said he believed an inquiry into it was appropriate: "When you have initial proof, as Summerlin does, that the judge who sentenced him used drugs, I think that triggers an entitlement to ask questions".
As an initial proof-of-concept experiment, we used LEMONS to investigate the performance of chemical similarity methods given libraries of short polymers of proteinogenic amino acids.
As an initial proof-of-principle we used the conditional gene expression assay presented herein to demonstrate by two different approaches the involvement of the p38 MAPK pathway during terminal differentiation of human myocytes in vitro.
As an initial proof-of-concept, we created functional ICCRs using the inward rectifier K+ channel Kir6.2 and two distinct model receptors: the muscarinic receptor M2 and the long dopaminergic receptor D2[1].
Nonetheless, we believe it is adequate for demonstrating the functionality of the assay as an initial proof-of-concept phase.
As an initial proof-of-concept, we demonstrated the feasibility of such technology by successful profiling PBMCs in a rat CIA model.
As an initial proof-of-concept for this approach we chose to utilize Chlamydomonas reinhardtii (hereafter referred to as Chlamydomonas) as the alga whose cell wall is the most studied to date [ 3, 5].
