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.

文献和实验对儿茶酚胺反应的受体，有α和β二类，α受体是其中一种。α受体一般表现兴奋性反应，儿茶酚胺与α受体作用可引起血管、子宫、输精管等的平滑肌收缩。阻断这一反应的药物为α阻断剂，有麦角碱、地苯那明（Dibenamine，双苄胺）、苯氧基苯胺等。
佚名 一、α 1， α 2 受体激动药 去甲肾上腺素 【来源及化学】 去甲肾上腺素（noradrenaline ,NA；norepinephrine,NE）是去甲肾上腺素能神经末梢释放的主要递质，也可由肾上腺髓质少量分泌。药用的是人工合成品，化学性质不稳定，见光易失效，在中性尤其
药用肾上腺素可从家畜肾上腺提取，或人工合成。理化性质与NA相似。 【体内过程】口服后在碱性肠液及肠粘膜和肝内破坏，吸收很少，不能达到有效血药浓度。皮下注射因能收缩血管，故吸收缓慢。肌内注射的吸收远较皮下注射为快。肾上腺素在体内的摄取与代谢途径与去甲肾上腺素相似（图10-2）。肌内注射作用维持约10～30分钟，皮下注射作用维持1小时左右。 【药理作用】肾上腺素能激动α和β两类受体，产生较强的α型和β型作用。 1. 心脏 作用于心肌、传导系统和窦房结的β
