Human serum albumin  (Synonyms: HSA)

目錄號: HY-P1956 純度: 99.9%
COA 產(chǎn)品使用指南

Human serum albumin (HSA) 是血漿中含量最高的蛋白質(zhì),是影響血漿瘤壓的主要因素。Human serum albumin 具有抗氧化、抗凝血、抗炎、抗血小板聚集活性以及膠體滲透作用。Human serum albumin 能阻止 GML 抑制人類 T 細胞的能力,實現(xiàn)對 T 細胞功能的保護。Human serum albumin 也與心血管疾病相關(guān),能部分阻止 LPS (HY-D1056) 誘導的氧化應激以及血管壁中 NF-κB、iNOS 和 過氧亞硝酸根 (ONOO?) 上調(diào)的血壓降低

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].

體外研究
(In Vitro)

Human serum albumin (5 μM, 0-90 分鐘) 能與 Glycerol monolaurate (GML) 結(jié)合,Kd 值為 1.4 μM。HSA 可以阻止 GML 抑制人類 T 細胞的能力,實現(xiàn)對 T 細胞功能的保護[3]
Human serum albumin (0.01, 0.05, 0.1μM, 0-24 小時) 能緩解 GML 誘導的 AKT 在蘇氨酸 308 和絲氨酸 473 位點的磷酸化以及 LAT、PLC-γ1 和 AKT 微集團形成,并在 GML 處理的細胞中恢復 IFN-γ、IL-2、IL-10 和 TNF-α 的產(chǎn)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.
體內(nèi)研究
(In Vivo)

Human serum albumin (10 ml/kg; 靜脈注射; 1 小時和 5 小時各1次; 2 次) 在 Male Swiss 小鼠模型中部分阻止了 LPS (HY-D1056) (50 mg/kg) 誘導的氧化應激以及血管壁中 NF-κBiNOS 和 過氧亞硝酸根 (ONOO?) 上調(diào)的血壓降低[4]。
Human serum albumin (10 ml/kg; 靜脈注射; 1 小時和 5 小時, 2 次) 在 Male Swiss 小鼠模型中能完全防止了由內(nèi)毒素誘導的對酚兒茶酚胺的血管反應減弱、肌電張力以及內(nèi)皮功能障礙,并且減少導致氧化和亞硝態(tài)應激以及血管反應性減弱的炎癥過程[4]。

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.
