【人臍動(dòng)脈內(nèi)皮細(xì)胞】下面是細(xì)胞株培養(yǎng)的具體無菌技術(shù)要點(diǎn)：

1. 實(shí)驗(yàn)開始前，無菌室和無菌操作臺(tái)需要紫外光照射30到60分鐘完全滅菌，用70%ethanol擦拭無菌操作臺(tái)面，并且打開無菌操作臺(tái)風(fēng)扇運(yùn)行10分鐘之后，才可以進(jìn)行實(shí)驗(yàn)操作。每次操作只能處理一株細(xì)胞株，即使培養(yǎng)基完全相同也不可共用培養(yǎng)基，以避免細(xì)胞間污染或失誤混淆。實(shí)驗(yàn)完成后，請(qǐng)將實(shí)驗(yàn)物品拿出工作臺(tái)，用70%ethanol再次擦拭無菌操作臺(tái)面。操作間隔應(yīng)該讓無菌操作臺(tái)運(yùn)轉(zhuǎn)10分鐘到15分鐘后，才能進(jìn)行下一個(gè)細(xì)胞株的操作。

2. 無菌操作工作的區(qū)域應(yīng)保持清潔和寬敞，必要物品（試管架、吸管、吸取器或吸管盒等）可以暫時(shí)放置，其它實(shí)驗(yàn)用品使用完畢后應(yīng)移出，有利于空氣流通。實(shí)驗(yàn)用品需70%ethanol擦拭后方可帶入無菌操作臺(tái)內(nèi)。實(shí)驗(yàn)操作過程應(yīng)在臺(tái)面的中央無菌區(qū)域內(nèi)完成，請(qǐng)勿在邊緣非無菌區(qū)域進(jìn)行操作。

3. 小心取用無菌實(shí)驗(yàn)物品，避免細(xì)菌污染。請(qǐng)勿觸碰吸管尖頭部和容器瓶口處，也不要在打開的容器正上方進(jìn)行操作。容器打開后，請(qǐng)用手夾住瓶蓋并輕握瓶身，傾斜大約45°角取用，盡量不要將瓶蓋口朝上放置于桌面。

4. 工作人員應(yīng)當(dāng)首先注意自身安全，必須穿戴齊實(shí)驗(yàn)衣和實(shí)驗(yàn)手套后才能進(jìn)行實(shí)驗(yàn)。對(duì)于病毒感染或是來自人類的細(xì)胞株應(yīng)當(dāng)特別小心操作，并選擇適當(dāng)?shù)燃?jí)的無菌操作臺(tái)進(jìn)行（至少是Class II）。操作過程中，應(yīng)避免引起aerosol的產(chǎn)生，小心有毒性藥品，例如DMSO和TPA等，并避免針頭的傷害等等。

5. 定期檢測(cè)下列項(xiàng)目：

5.1. CO2鋼瓶的CO2壓力

5.2. CO2培養(yǎng)箱的CO2濃度、溫度、和水盤是否有污染（水盤的水需用無菌水，每周定時(shí)更換）。

5.3. 無菌操作臺(tái)內(nèi)的airflow壓力，定期更換紫外線燈管和HEPA過濾膜，預(yù)濾網(wǎng)（300小時(shí)/預(yù)濾網(wǎng)，3000小時(shí)/HEPA）。

6. 水槽內(nèi)可添加消毒劑（Zephrin 1:750），需定期更換水槽中的水。

【人臍動(dòng)脈內(nèi)皮細(xì)胞】五、培養(yǎng)方法

 收到細(xì)胞后，在倒置顯微鏡下觀察整個(gè)細(xì)胞生長(zhǎng)情況：

 如果細(xì)胞未長(zhǎng)滿，用 75%酒精噴灑整個(gè)瓶消毒后放到超菌臺(tái)內(nèi)，嚴(yán)格無菌操作，打開細(xì)胞培養(yǎng)瓶，留10ml 培養(yǎng)液繼續(xù)培養(yǎng)。如果細(xì)胞已長(zhǎng)滿（達(dá) 80-90%）。即可進(jìn)行傳代，具六、體步驟如下：

1，棄去培養(yǎng)液，用PBS洗 1-2次。

2，向瓶?jī)?nèi)加入 1.0-2.0ml 胰蛋白酶液，在倒置顯微鏡下觀察細(xì)胞消化情況，若細(xì)胞大部分變圓，迅速拿回操作臺(tái)，吸取胰蛋白酶，加含有 6ml  含 10%血清的培養(yǎng)液，輕輕吹打細(xì)胞。

3，加入等量的的培養(yǎng)液，輕輕吹打混勻后吸出一半，分到新的培養(yǎng)

4，傳代比例：1:2-1:3  

七、常見問題及解決方案

1、培養(yǎng)瓶有破裂，培養(yǎng)液有漏液：細(xì)胞極大可能會(huì)污染，所以我們會(huì)及時(shí)安排幫老師解決。

2、細(xì)胞漂�。号囵B(yǎng)瓶不開封，瓶口酒精擦拭后平躺放置在培養(yǎng)箱。次日觀察，如細(xì)胞大部分又貼回瓶底，表明細(xì)胞活力正常，剩余漂浮的細(xì)胞可以去掉，留 10ml 培養(yǎng)液培養(yǎng)觀察，細(xì)胞生長(zhǎng)至匯合度 80%，進(jìn)行消化傳代；如細(xì)胞還是不貼壁，將細(xì)胞離心收集轉(zhuǎn)到新培養(yǎng)瓶，原培養(yǎng)瓶加部分培養(yǎng)液繼續(xù)培養(yǎng)，中間注意觀察，我們的技術(shù)人員會(huì)一直跟蹤指導(dǎo)，直到問題解決。

9243652Comprehen Valid., QuantiPlex/QP Hyres"""The Comprehensive Validation Support plan specific to a laboratory＇s needs will incorporate all of the requirements for the internal validation guidelines from the FBI＇s Quality Assurance Standards (QAS).

The Comprehensive Validation Support service includes all travel ａnd labor charges for up to 20 days by the QIAGEN Validation Team. Typically, one week will be required to extract, quantify, ａnd amplify the validation study samples ａnd may require multiple individuals. Usually, two weeks is required to analyze the data ａnd one week to write the final report. The expected time period to complete the Comprehensive Validation is six weeks. The actual time may vary depending on resource availability, including laboratory time dedicated to validation activities.

Lab Work – The QIAGEN specialist(s) will travel to the laboratory to conduct the on-site validation lab work. The QIAGEN specialist team will perform ａnd complete all extractions, quantifications, amplfications, ａnd capillary electrophoresis. The laboratory is responsible for providing systems/protocols that may be needed (generally laboratory SOPs, ex. interpretation guidelines). Additionally, the laboratory staff may be required to provide additional data needed for interpretation (ex. quantification/amplification/CE results) during the data review phase of the validation. 

Once the final scope of the validation is determined, QIAGEN will provide a quote for all consumables required for the validation.  Non-QIAGEN chemistry ａnd accessories are not included ａnd should  be purchased to cover the validation experimental design including qPCR, STR, NIST standards, required samples types (blood, semen, buccal samples) ａnd required substrates (swabs, materials, etc).   For planning purposes ａnd to ensure a smooth process, the Customer is expected to have all materials on-hand ａnd inventoried one (1) week prior to the validation start date.

Data Analysis – The Comprehensive Validation Support plan encompasses data collection (quants, amps, CE) during the on-site visit. The laboratory may be responsible for sharing (typically electronically via e-mail) any validation data requested after the on-site visit. A QIAGEN specialist will complete all of the data analysis produced from the validation study design. This includes qPCR (quant) ａnd STR (amp) analysis ａnd linkage to starting samples.

Validation data CD/flashdrive – QIAGEN will review the validation data ａnd draft a validation summary document, ensuring compliance with the FBI＇s QAS requirements/standards. QIAGEN will send validation data in an electronic format (email/CD/flashdrive) to the laboratory. The laboratory is responsible for final compilation, any format change preferences, review ａnd signoff of the validation report. The documentation provided by QIAGEN will aide in demonstrating compliance with all accreditation guidelines during laboratory audits. Should a hard copy of the validation study be preferred, the laboratory is required to specify prior to the onset of the validation.

Post-validation QIAGEN-to-Laboratory Transfer – Following completion of the validation ａnd generation of the draft validation summary document, a designated member of the QIAGEN validation team will review the validation with the Lab Manager ａnd the Technical Leader. Following sign off on the validation report, training of the laboratory DNA staff will occur. Refer to the Post-validation Competency Training for additional information. """CNY
