    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Importantly however, the number of channels is constrained by mechanical considerations in multichannel pipettes, whereas the MS simplicity enables the number of simultaneous “channels” to scale well beyond traditional limitations. Indeed, we developed 4-channel, 8-channel, and a 24-channel versions for the purpose of large-scale multiplex purification reactions, as well as a custom rack designed for a 24-channel MS to elute directly into a 96 or 384-well plate (Figure 9B and 9C). Second, this superior scaling potential also reduces the additional processing time required by more samples. The addition of every 8 samples increases the required processing time with an 8-channel multipipette, but a 24-channel MS increases processing time only beyond 24 samples. The processing time is further reduced because 2-3 pipetting steps are replaced with a single dipping step. Third, the cost of a MS is dramatically less than a multichannel pipette. A 24-channel magnetic stick costs less than $5.00 to produce, and each tip is less than $0.05, about $6.00 in total. An 8-channel multipipette in contrast costs well over a thousand dollars. Our purification optimization results also suggest several unexplored directions for future saliva-based nucleic acid diagnostics. The optimal NaCl concentrations were well below the theoretical limit required for purifying nucleic acids, suggesting that uncharacterized minerals or salts present in saliva are aiding nucleic acid binding to carboxylated bea...

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
