一般描述
Cohn 馏分 IV 由 α 和 β-球蛋白组成。它是 γ-球蛋白合成过程中产生的血浆副产物。
应用
人球蛋白 Cohn 部分 IV-4 已用在差示扫描量热法（DSC） 中测试低剂量电离辐射的效果。它还被用于制备用于生物物理研究的血浆蛋白溶液。
球蛋白可以将 5-甲氧基补骨脂素与血液组分结合。可用作粒细胞免疫荧光试验（GIFT）的阳性对照。它还可用于研究人血清蛋白混合物的热变性。
生化/生理作用
Cohn 组分 IV（富含 α-珠蛋白）介导脑神经递质受体的抑制。
其他说明
主要是 α-和 β-球蛋白

Human serum proteins are found in significant density in the neuropil in brains of demented individuals. The functional significance of these abnormally distributed proteins has been unknown. We now report that alpha-globulin-enriched fractions of human serum decrease the specific binding

More frequent and widespread nerve agent attacks highlight the need for efficacious pre- and post-exposure organophosphate (OP) counter-measures to protect military and civilian populations. Because of critical targeting of acetylcholinesterase (AChE) in the CNS by OPs, a pre-treatment candidate for

The binding of 5-methoxypsoralen (5-MOP) to human serum and blood fractions was studied by equilibrium dialysis associated to high-performance liquid chromatography. 5-MOP serum binding was 95% and kept constant in the range of therapeutic concentrations. Albumin was the main binding

Hypochlorous acid (HOCl), a powerful antimicrobial oxidant, is produced by neutrophils to fight infections. Here, we show that N-chlorination, induced by HOCl concentrations encountered at sites of inflammation, converts blood plasma proteins into chaperone-like holdases that protect other proteins from
