抗原修复——原因 *常规的石蜡切片标本均用甲醛固定,结果使得: -抗原性物质形成醛键、羧甲键而被封闭了部分抗原决定簇; -蛋白之间发生交联而使抗原决定簇隐蔽。 *要求:在染色时,需要先进行抗原修复或暴露,即将固定时分子之间所形成的交联破坏,而恢复抗原的原有空间形态抗原修复——方法 *化学方法 *加热方法 -水浴加热法 -微波照射法 -高压加热法 -酸水解法
抗体(antibody)指机体的免疫系统在抗原刺激下,由B淋巴细胞或记忆细胞增殖分化成的浆细胞所产生的、可与相应抗原发生特异性结合的免疫球蛋白。主要分布在血清中,也分布于组织液及外分泌液中。

Catecholamine, a term used for the hormone adrenaline and its sequentially hydroxylated form noradrenaline, is involved in fight or flight responses. Noradrenaline is released from the post ganglionic sympathetic nerve endings and exerts its effects locally in the immediate vicinity of its release. In the CNS, noradrenaline is involved in a number of physiological responses including mood, sleep regulation, alertness and arousal, both cognitive and non-cognitive expression of behaviors, and control of the endocrine and autonomic nervous systems. Peripherally, noradrenaline is present in sympathetic nerve endings and has full control of the sympathetic nervous system. Noradrenaline released from pre-synaptic nerve terminals is reabsorbed (70-90%) by noradrenaline transporters and its biological effects are terminated. The noradrenaline transport via noradrenaline transporters is an active, Na+/Cl- dependent transport process mediated by noradrenaline transporters. Noradrenaline transporters constitute the primary mechanism for inactivation of synaptically released noradrenaline, are targets for multiple antidepressants and psychostimulants, and are deficient in affective and autonomic disorders. In rat brain, noradrenaline transporter is expressed in noradrenergic neuronal somata, axons and dendrites, and hippocampus and cortex, but is absent from epinephrine- and dopamine-containing neurons. At least 13 genetic variations have been reported in the noradrenaline transporter protein that affect noradrenaline re-uptake and concentrations in cerebrospinal fluid in humans. The association between these genetic variations in noradrenaline transporters and several psychiatric and cardiovascular disorders is just emerging. Recently, a single amino acid mutation (hNET-A457P) showed deficiency in noradrenaline transport in an orthostatic intolerance patient. Noradrenaline transporter protein consists of 617 amino acids and has 12 trans-membrane domains, a characteristic feature of many membrane associated solute transporters.
抗体是具有4条多肽链的对称结构,其中2条较长、相对分子量较大的相同的重链(H链);2条较短、相对分子量较小的相同的轻链(L链)。链间由二硫键和非共价键联结形成一个由4条多肽链构成的单体分子。轻链有κ和λ两种,重链有μ、δ、γ、ε和α五种。 整个抗体分子可分为恒定区和可变区两部分。在给定的物种中,不同抗体分子的恒定区都具有相同的或几乎相同的氨基酸序列。可变区位于"Y"的两臂末端。在可变区内有一小部分氨基酸残基变化特别强烈,这些氨基酸的残基组成和排列顺序更易发生变异区域称高变区。高变区位于分子表面,多由17个氨基酸残基构成,少则只有2 ~ 3个。高变区氨基酸序列决定了该抗体结合抗原抗原的特异性。一个抗体分子上的两个抗原结合部位是相同的,位于两臂末端称抗原结合片段(antigen-binding fragment, Fab)。"Y"的柄部称结晶片段(crystalline fragment,FC),糖结合在FC 上。
