一般描述
触珠蛋白是一种在正常血浆中发现的 α 2 -球蛋白，浓度为 82-236 mg/dL，占血浆总蛋白的 0.4-2.6%。这种急性期血浆蛋白的单体形式由四条多肽链组成：两条 α链和两个 β链条。
触珠蛋白是一种急性期蛋白，可清除释放到循环中的血红蛋白。结合珠蛋白是与血红蛋白亲和力最高的血浆蛋白，主要在肝脏中表达。
应用
结合珠蛋白用于研究诱导精子顶体反应。暴露于低温会增加它们与无透明带仓鼠卵母细胞的融合率。
生化/生理作用
通过与血浆血红蛋白结合（来自溶血）发挥作用。该复合物通过与巨噬细胞上的 CD163 受体结合，从循环中清除，以挽救铁并防止氧化损伤。
其他说明
作为 3 种主要表型出现：1-1 型、2-1 型、2-2 型。

The N-glycans attached to proteins contain various GlcNAc branches, the aberrant formation of which correlates with various diseases. N-Acetylglucosaminyltransferase-IVa (GnT-IVa or MGAT4A) and Gnt-IVb (or MGAT4B) are isoenzymes that catalyze the formation of the β1,4-GlcNAc branch in N-glycans. However, the

Quantitative point-of-care (POC) devices are the next generation for serological disease diagnosis. Whilst pathogen serology is typically performed by centralized laboratories using Enzyme-Linked ImmunoSorbent Assay (ELISA), faster on-site diagnosis would infer improved disease management and treatment decisions.
