USAGE
Reconstitute in sterile PBS, pH7.2-pH7.4.
STORAGE AND STABILITY
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

文献和实验一、细胞因子的概念 细胞因子(cytokine)是由机体多种细胞分泌的小分子蛋白质,通过结合细胞表面的相应受体发挥以调节免疫应答为主的生物学作用。细胞因子具有 非常广泛的生物学活性,包括促进靶细胞的增殖和分化,增强抗感染和细胞杀伤效应,促进或抑制其它细胞因子和膜表面分子的表达,促进炎症过程,影响细胞代谢 等。 二、细胞因子的命名 细胞因子按其来源可分为:由单个核吞噬细胞产生的细胞因子称为单核因子(monokine);由淋巴细胞产生的细胞因子称为淋巴因子 (lymphokine
。 第二节 细胞培养基的基本要求 体外培养的细胞直接生活在培养基中,因此培养基应能满足细胞对营养成分、促生长因子、激素、渗透压、pH等诸多方面的要求。 一、营养成分 维持细胞生长的营养条件一般包括以下几个方面: 1、氨基酸:是细胞合成蛋白质的原料。所有细胞都需要12种必须氨基酸:缬氨酸、亮、异亮、苏、赖、色、苯丙、蛋、组、酪、精氨酸、胱氨酸。此外还需要谷氨酰胺,它在细胞代谢过程中有重要作用,所含的氮是核酸中嘌令和嘧啶合成的来源,同样也是合成三、二、一磷酸酰苷所需要的基本物质。 体外
