COA 产品使用指南

Human serum albumin (HSA) 是血浆中含量最高的蛋白质,是影响血浆瘤压的主要因素。Human serum albumin 具有抗氧化、抗凝血、抗炎、抗血小板聚集活性以及胶体渗透作用。Human serum albumin 能阻止 GML 抑制人类 T 细胞的能力,实现对 T 细胞功能的保护。Human serum albumin 也与心血管疾病相关,能部分阻止 LPS (HY-D1056) 诱导的氧化应激以及血管壁中 NF-κBiNOS 和 过氧亚硝酸根 (ONOO) 上调的血压降低

生物活性

Human serum albumin (HSA) is the most abundant protein in plasma and is a major determinant of plasma oncotic pressure. Human serum albumin exhibits antioxidant, anticoagulant, anti-inflammatory, anti-platelet aggregation activities as well as colloid osmotic action. Human serum albumin can block the inhibitory effect of GML on human T cells, providing protective function for T cells. Human serum albumin is also associated with cardiovascular diseases and can partially prevent the LPS (HY-D1056) induced oxidative stress, as well as the upregulation of NF-κB, NF-κB, and peroxynitrite (ONOO) in the vascular wall, contributing to the reduction of blood pressure[1][2][3].

体外研究
(In Vitro)

Human serum albumin (5 μM, 0-90 分钟) 能与 Glycerol monolaurate (GML) 结合,Kd 值为 1.4 μM。HSA 可以阻止 GML 抑制人类 T 细胞的能力,实现对 T 细胞功能的保护[3]
Human serum albumin (0.01, 0.05, 0.1μM, 0-24 小时) 能缓解 GML 诱导的 AKT 在苏氨酸 308 和丝氨酸 473 位点的磷酸化以及 LAT、PLC-γ1 和 AKT 微集团形成,并在 GML 处理的细胞中恢复 IFN-γ、IL-2、IL-10 和 TNF-α 的产生[3]

Western Blot Analysis[3]

Cell Line: Activate peripheral blood T cells
Concentration: 0.05 μM
Incubation Time: 0, 2, 5, 15 min
Result: Affected the ability of GML to inhibit AKT phosphorylation.

RT-PCR[3]

Cell Line: Activate peripheral blood T cells
Concentration: 0.1, 0.05, 0.005 μM
Incubation Time: 24h
Result: Restored the production of IFN-γ, IL-2, IL-10, and TNF-α in GML treated cells.
体内研究
(In Vivo)

Human serum albumin (10 ml/kg; 静脉注射; 1 小时和 5 小时各1次; 2 次) 在 Male Swiss 小鼠模型中部分阻止了 LPS (HY-D1056) (50 mg/kg) 诱导的氧化应激以及血管壁中 NF-κBiNOS 和 过氧亚硝酸根 (ONOO) 上调的血压降低[4]
Human serum albumin (10 ml/kg; 静脉注射; 1 小时和 5 小时, 2 次) 在 Male Swiss 小鼠模型中能完全防止了由内毒素诱导的对酚儿茶酚胺的血管反应减弱、肌电张力以及内皮功能障碍,并且减少导致氧化和亚硝态应激以及血管反应性减弱的炎症过程[4]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
