产品介绍 This gene encodes a hypothalamic neuropeptide precursor protein that gives rise to two mature neuropeptides, orexin A and orexin B, by proteolytic processing. Orexin A and orexin B, which bind to orphan G-protein coupled receptors HCRTR1 and HCRTR2, function in the regulation of sleep and arousal. This neuropeptide arrangement may also play a role in feeding behavior, metabolism, and homeostasis.
Function : Neuropeptides that play a significant role in the regulation of food intake and sleep-wakefulness, possibly by coordinating the complex behavioral and physiologic responses of these complementary homeostatic functions. A broader role in the homeostatic regulation of energy metabolism, autonomic function, hormonal balance and the regulation of body fluids, is also suggested. Orexin-A binds to both OX1R and OX2R with a high affinity, whereas orexin-B binds only to OX2R with a similar high affinity. 
Subcellular Location : Rough endoplasmic reticulum (By similarity). Cytoplasmic vesicle (By similarity). Cell junction, synapse (By similarity). Note=Associated with perikaryal rough endoplasmic reticulum as well as cytoplasmic large granular vesicles at synapses (By similarity). 
Tissue Specificity : Abundantly expressed in subthalamic nucleus but undetectable in other brain regions tested (hypothalamus was not tested) and in heart, placenta, lung, liver, skeletal muscle, kidney and pancreas.
Post-translational modifications : Specific enzymatic cleavages at paired basic residues yield the different active peptides. 
DISEASE : Defects in HCRT are the cause of narcolepsy type 1 (NRCLP1) [MIM:161400]. Narcolepsy is a neurological disabling sleep disorder, characterized by excessive daytime sleepiness, sleep fragmentation, symptoms of abnormal rapid-eye-movement (REM) sleep, such as cataplexy, hypnagogic hallucinations, and sleep paralysis. Cataplexy is a sudden loss of muscle tone triggered by emotions, which is the most valuable clinical feature used to diagnose narcolepsy. Human narcolepsy is primarily a sporadically occurring disorder but familial clustering has been observed. Note=Human narcolepsy is associated with a deficient orexin system. Orexins are absent and/or greatly diminished in the brain and cerebrospinal fluid (CSF) of most narcoleptic patients. 
Similarity : Belongs to the orexin family.

ELISA试剂盒操作步骤
使用前，将所有试剂充分混匀。不要使液体产生大量的泡沫，以免加样时加入大量的气泡，产生加样上的误差。
根据待测样品数量加上标准品的数量决定所需的板条数。每个标准品和空白孔建议做复孔。每个样品根据自己的数量来定，能使用复孔的尽量做复孔。标本用标本稀释液1：1稀释后加入50ul于反应孔内。
加入稀释好后的标准品50ul于反应孔、加入待测样品50ul于反应孔内。立即加入50ul的生物素标记的抗体。盖上膜板，轻轻振荡混匀，37℃温育1小时。
甩去孔内液体，每孔加满洗涤液，振荡30秒，甩去洗涤液，用吸水纸拍干。重复此操作3次。如果用洗板机洗涤，洗涤次数增加一次。
每孔加入80ul的亲和链酶素-HRP，轻轻振荡混匀，37℃温育30分钟。
甩去孔内液体，每孔加满洗涤液，振荡30秒，甩去洗涤液，用吸水纸拍干。重复此操作3次。如果用洗板机洗涤，洗涤次数增加一次。
每孔加入底物A、B各50ul，轻轻振荡混匀，37℃温育10分钟。避免光照。
取出酶标板，迅速加入50ul终止液，加入终止液后应立即测定结果。
在450nm波长处测定各孔的OD值。
