一般描述
硼酸是一种弱酸，广泛用作多功能溶液（MPS）的缓冲剂。它在自然界中毒性较低，不挥发。
应用
硼酸已被用作tris硼酸盐缓冲液缓冲液的成分：
- 用于tRNA样品（80）的天然聚丙烯酰胺凝胶电泳（PAGE）和尿素变性PAGE
- RNA样品（81）的尿素聚丙烯酰胺电泳
- DNA样品（82）的琼脂糖凝胶电泳
生化/生理作用
硼酸可用作牙周治疗中的冲洗液，因为它会引发根管微生物生物膜的杀菌作用。 硼酸可促进成骨细胞活性并抑制骨质流失。它会抑制白色念珠菌造成的真菌感染，并具有治疗阴道感染的潜力。

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific accumulation

The human solute carrier (SLC26) family of anion transporters consists of 10 members (SLCA1-11, SLCA10 being a pseudogene) that encode membrane proteins containing ~12 transmembrane (TM) segments with putative N-glycosylation sites (-NXS/T-) in extracellular loops and a COOH-terminal cytosolic STAS
