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，細胞剛有脫落時，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（每個平皿可放置2-3片）； 

3．在距離紫外燈直射范圍內20-30 厘米處照射2-3小時； 

4．將經過計數(shù)的細胞懸浮液移入培養(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，當貼壁細胞生長至覆蓋培養(yǎng)板底部2/3面積時，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行快速固定以及細胞化學檢測。 

細胞培養(yǎng)方法：

1、細胞傳代：細胞密度達到80-90%時即可傳代

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），使胰酶覆蓋整個瓶或皿，蓋好放入培養(yǎng)箱消化；

③1-2min后，顯微鏡下觀察細胞，若大部分細胞回縮且有少量細胞脫落，輕輕吹打下確認消化情況后加入完全培養(yǎng)基終止消化；若細胞還是貼壁，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懸浮細胞直接離心收集，細胞沉淀重懸后分到新培養(yǎng)瓶中。

2、細胞復蘇：

①將凍存管在37℃溫水中快速搖晃融化，時間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，將細胞懸液加入培養(yǎng)瓶中，補加適量培養(yǎng)基。

3、細胞凍存：待細胞生長狀態(tài)良好時進行細胞凍存保種

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

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

④將凍存管放入程序降溫盒，放入-80℃冰箱，4小時后將凍存管轉入液氮罐儲存。

產品介紹 SHP1 is a member of the non receptor protein tyrosine phosphatase subfamily. The PTP family comprises of at least 37 proteins, characterized by a catalytic phosphatase domain of approximately 240 amino acids, and includes both transmembrane and cytosolic enzymes. PTP1B is cytosolic. The PTPs have high substrate specificity for phosphotyrosyl proteins, at the primary sequence level sharing little similarity with the protein serine phosphatases, protein threonine phosphatases, or the acid and alkaline phosphatases. SHP1 is implicated in the control of tyrosine kinase signalling pathways in cellular proliferation, with a potential role in cancer.

Function : Modulates signaling by tyrosine phosphorylated cell surface receptors such as KIT and the EGF receptor/EGFR. The SH2 regions may interact with other cellular components to modulate its own phosphatase activity against interacting substrates. Together with MTUS1, induces UBE2V2 expression upon angiotensin II stimulation. Plays a key role in hematopoiesis.

Subunit : Monomer. Interacts with MTUS1. Interacts with MILR1 (tyrosine-phosphorylated). Interacts with KIT. Binds PTPNS1, LILRB1 and LILRB2. Interacts with FCRL2, FCRL3, FCRL4, CD300LF, CDK2 and CD84. Interacts with KIR2DL1; the interaction is enhanced by ARRB2. Interacts (via SH2 1 domain) with ROS1; the interaction is direct and promotes ROS1 dephosphorylation. Interacts with EGFR; inhibits EGFR-dependent activation of MAPK/ERK. Interacts with LYN. Interacts with the tyrosine phosphorylated form of PDPK1.

Subcellular Location : Cytoplasm. Nucleus. Note=In neurons, translocates into the nucleus after treatment with angiotensin II. Shuttles between the cytoplasm and nucleus via its association with PDPK1.

Tissue Specificity : Isoform 1 is expressed in hematopoietic cells. Isoform 2 is expressed in non-hematopoietic cells.

Post-translational modifications : Phosphorylated on tyrosine residues. Binding of KITLG/SCF to KIT increases tyrosine phosphorylation. Phosphorylation at Tyr-564 enhances phosphatase activity.

Similarity : Belongs to the protein-tyrosine phosphatase family. Non-receptor class 2 subfamily.

Contains 2 SH2 domains.

Contains 1 tyrosine-protein phosphatase domain.

實驗要點及說明：

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

2．所使用的蓋玻片應該為玻璃**，并經過鉻酸洗液處理； 

3．蓋玻片非常薄，易碎，取放蓋玻片時動作要輕； 

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

5．如果細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。
