phosphate buffer 即磷酸盐缓冲液，能够提供相对稳定的离子环境和 pH 缓冲能力，是生物学中经常使用的缓冲盐溶液。

存储：室温储存，有效期至少 12 个月。

本产品为浓度为0.1M，经过0.2μm除菌处理， 4℃保存可延长产品保质期，长期不用建议低温保存。

注意事项：

在使用 PBS 的过程中要特别注意避免溶液被微生物污染。

PBS 在低温情况下可能会产生沉淀。如果发现有沉淀产生，请置于 37℃水浴至完全溶解后再使用。

为了您的安全和健康，请穿实验服并戴一次性手套操作。

Phosphate-buffered saline (abbreviated PBS) is a buffer solution commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH. The osmolarity and ion concentrations of the solutions match those of the human body (isotonic).

When making buffer solutions, it is good practice to always measure the pH directly using a pH meter. If necessary, pH can be adjusted using hydrochloric acid or sodium hydroxide.
