说明

應用

• Systematic development of immunohistochemistry protocol for large cryosections-specific to non-perfused fetal brain.: This study by Pandurangan et al. highlights the role of boric acid in developing an optimized immunohistochemistry protocol for large cryosections of non-perfused fetal brain tissues. Boric acid is used as a buffer component to enhance antigen retrieval and staining specificity, showcasing its importance in neuroanatomical research (Pandurangan et al., 2024).


• Proteomic Analysis of Rat Duodenum Reveals the Modulatory Effect of Boron Supplementation on Immune Activity.: Zhao et al. investigate the impact of boric acid on immune activity through proteomic analysis of rat duodenum. The study demonstrates boric acids role in modulating protein expression related to immune responses, providing insights into its potential applications in immunology and nutritional biochemistry (Zhao et al., 2023).


• The impact of boron nutrient supply in mulberry (Morus alba) response to metabolomics, enzyme activities, and physiological parameters.: Zhang et al. explore the effects of boric acid on mulberry plants′ metabolic profiles, enzyme activities, and physiological parameters. This research underscores boric acids significance in plant nutrition and stress response, offering valuable data for agricultural chemistry and plant sciences (Zhang et al., 2023).
