应用



  • Utilization in Bioprinting Research: Sodium standard solutions are used to measure cell proliferation in bioprinting research, aiding in the validation of cell viability and proliferation metrics. This application underscores the importance of precise sodium ion quantification in tissue engineering (Schweinitzer et al., 2024, https://doi.org/10.1088/1748-605X/ad3700).


  • Quantitative Plant Proteomics: Sodium standards are critical for maintaining method linearity in quantitative plant shotgun proteomics, ensuring accurate measurement of protein concentrations. Their application is vital for reproducible quantification in biochemical assays (Leonova et al., 2022, https://doi.org/10.3389/fpls.2022.874761).


  • Evaluation of Mineral Composition: High-purity sodium standards are utilized in the evaluation of mineral compositions, serving as reference points in comparative studies of various biological samples. This usage highlights their role in precise and traceable analytical assessments (Evuen et al., 2022, https://doi.org/10.1038/s41598-022-25204-3).
