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(zhǎng)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(guò)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(wú)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(guò)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(zhǎng)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(cè)。 

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(zhǎng)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 PDZK7, also known as PDZD7, is a 517 amino acid protein that contains two PDZ (DHR) domains. Encoded by a gene that maps to human chromosome 10q24.31, PDZK7 is conserved in dog, mouse and rat, and exists as three alternatively spliced isoforms. PDZK7 is known to interact with Harmonin, MASS1, USH1G and Usherin. Localizing to nucleus, PDZK7 is expressed in retinal pigment epithelium and inner ear. Biallelic inactivation of PDZK7 can cause non-syndromic hearing impairment and chromosomal aberrations, which are linked to non-syndromic sensorineural deafness. PDZK7 mutations are also linked to Usher syndrome, which is characterized by retinitis pigmentosa and sensorineural deafness, and Alzheimer disease. The gene that encodes PDZK7 maps to human chromosome 10q24.31.

Subunit : Interacts with USH1G. Interacts with GPR98. Interacts with USH2A.

Subcellular Location : Cell projection; cilium. Nucleus.

Tissue Specificity : Weakly expressed in the inner ear. Expressed in the retinal pigment epithelium.

DISEASE : Note=A chromosomal aberration disrupting PDZD7 has been found in patients with non-syndromic sensorineural deafness. Translocation t(10;11),t(10;11).

Defects in PDZD7 are a cause of Usher syndrome type 2C (USH2C) [MIM:605472]. USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH2 is characterized by congenital mild hearing impairment with normal vestibular responses. Note=PDZD7 mutations have been found in combination with mutations in USH2A and GPR98 in patients affected by Usher syndrome, suggesting a role as contributor to digenic Usher syndrome or a modifier of retinal disease expression.

Similarity : Contains 2 PDZ (DHR) domains.

實(shí)驗(yàn)要點(diǎn)及說(shuō)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(guò)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(zhǎng)狀態(tài)一致的細(xì)胞，可以使用較大的培養(yǎng)皿，但不宜過(guò)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(zhǎng)能力較差，可將蓋玻片在0.5%多聚賴(lài)氨酸溶液中浸泡5-10分鐘并自然晾干。
