實(shí)驗(yàn)要點(diǎn)及說明：

1．本方法適用于貼壁細(xì)胞培養(yǎng)，而不適用于懸浮細(xì)胞培養(yǎng)，懸浮細(xì)胞可使用滴片法； 

2．所使用的蓋玻片應(yīng)該為玻璃**，并經(jīng)過鉻酸洗液處理； 

3．蓋玻片非常薄，易碎，取放蓋玻片時(shí)動(dòng)作要輕； 

4．如果需要更多生長狀態(tài)一致的細(xì)胞，可以使用較大的培養(yǎng)皿，但不宜過大，以避免培養(yǎng)液的浪費(fèi)和增加污染機(jī)率； 

5．如果細(xì)胞貼壁生長能力較差，可將蓋玻片在0.5%多聚賴氨酸溶液中浸泡5-10分鐘并自然晾干。

培養(yǎng)方法

傳代方法 將舊培養(yǎng)液吸除，PBS清洗兩遍后，加入6mL（/100mm皿）胰酶，在顯微鏡下觀察，期間禁止搖晃培養(yǎng)皿，細(xì)胞剛有脫落時(shí)，則吸除大部分胰酶，留約0.5mL，移至培養(yǎng)箱消化，約2min取出。傳代用12mL CM1-1培養(yǎng)液終止消化，輕輕吹打均勻細(xì)胞，后可分3~6皿培養(yǎng)；

生長條件 37℃，5%CO2，CM1-1培養(yǎng)液。CM1-1培養(yǎng)液：90%DMEM-H+10%FBS。DMEM-H：DMEM高糖培養(yǎng)液，含谷氨酰胺，含丙酮酸鈉。

存儲(chǔ)條件 凍存則用6mL凍存液（90%FBS+10%DMSO）終止消化，吹打均勻，分為6支凍存管，用程序降溫盒于-80℃凍存，過夜轉(zhuǎn)移至液氮中保存。

培養(yǎng)操作步驟 ：

1．用蓋片鑷將蓋玻片自75%乙醇中取出，用無菌絲綢布擦拭干凈，不要用紗布； 

2．將蓋玻片輕輕放入6孔培養(yǎng)板（每孔一片）或培養(yǎng)皿中（每個(gè)平皿可放置2-3片）； 

3．在距離紫外燈直射范圍內(nèi)20-30 厘米處照射2-3小時(shí)； 

4．將經(jīng)過計(jì)數(shù)的細(xì)胞懸浮液移入培養(yǎng)板中，使蓋玻片完全浸在培養(yǎng)液中； 

5．將培養(yǎng)板在5% CO2水浴孵箱中37℃孵育2-3天，當(dāng)貼壁細(xì)胞生長至覆蓋培養(yǎng)板底部2/3面積時(shí)，將培養(yǎng)板取出，用蓋片鑷輕輕取出蓋玻片，用蒸餾水漂洗后即可進(jìn)行快速固定以及細(xì)胞化學(xué)檢測。 

細(xì)胞培養(yǎng)方法：

1、細(xì)胞傳代：細(xì)胞密度達(dá)到80-90%時(shí)即可傳代

①棄去培養(yǎng)上清，用PBS或生理鹽水清洗1-2次；

②加入2ml0.25%胰酶（T25瓶），使胰酶覆蓋整個(gè)瓶或皿，蓋好放入培養(yǎng)箱消化；

③1-2min后，顯微鏡下觀察細(xì)胞，若大部分細(xì)胞回縮且有少量細(xì)胞脫落，輕輕吹打下確認(rèn)消化情況后加入完全培養(yǎng)基終止消化；若細(xì)胞還是貼壁，放回培養(yǎng)箱繼續(xù)消化至可以輕輕吹打下為止；

④將細(xì)胞懸液1000RPM左右條件下離心4min，棄上清；

⑤用新鮮培養(yǎng)基重懸后加入培養(yǎng)瓶或皿中，T25培養(yǎng)瓶加6-8ml培養(yǎng)基；

⑥懸浮細(xì)胞直接離心收集，細(xì)胞沉淀重懸后分到新培養(yǎng)瓶中。

2、細(xì)胞復(fù)蘇：

①將凍存管在37℃溫水中快速搖晃融化，時(shí)間1min左右，加入4-5ml培養(yǎng)基混勻。

②在1000RPM左右條件下離心4min，棄上清,加1-2ml培養(yǎng)基吹勻，將細(xì)胞懸液加入培養(yǎng)瓶中，補(bǔ)加適量培養(yǎng)基。

3、細(xì)胞凍存：待細(xì)胞生長狀態(tài)良好時(shí)進(jìn)行細(xì)胞凍存保種

①棄去培養(yǎng)上清，用PBS或生理鹽水清洗1-2次，加入1mL 0.25%胰蛋白酶（T25瓶）

②1-2min后，顯微鏡下觀察細(xì)胞，大部分細(xì)胞回縮且有少量細(xì)胞脫落，輕輕吹打下確認(rèn)消化情況后加入完全培養(yǎng)基終止消化；

③將細(xì)胞懸液1000RPM左右條件下離心4min，棄上清，加1ml凍存液重懸細(xì)胞；

④將凍存管放入程序降溫盒，放入-80℃冰箱，4小時(shí)后將凍存管轉(zhuǎn)入液氮罐儲(chǔ)存。

產(chǎn)品介紹 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.
