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,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;
4.將經(jīng)過計數(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,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(xì)胞化學(xué)檢測。

實驗要點及說明:
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,取放蓋玻片時動作要輕;
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)液的浪費和增加污染機率;
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。
細(xì)胞培養(yǎng)方法:
1、細(xì)胞傳代:細(xì)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(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)良好時進行細(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小時后將凍存管轉(zhuǎn)入液氮罐儲存。

not yet tested in other applications.
optimal dilutions/concentrations should be determined by the end user.
保存條件 Store at -20 °C for one year. Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two including a reduction of nitric oxide (NO) release, monocyte adhesion and apoptosis. In addition to binding oxLDL, it acts as a receptor for the HSP70 protein involved in antigen cross-presentation to naive T-cells in dendritic cells, thereby participating in cell-mediated antigen cross-presentation. Also involved in inflammatory process, by acting as a leukocyte-adhesion molecule at the vascular interface in endotoxin-induced inflammation. Also acts as a receptor for advanced glycation end (AGE) products, activated platelets, monocytes, apoptotic cells and both Gram-negative and Gram-positive bacteria.
Subunit : Homodimer; disulfide-linked. May form a hexamer composed of 3 homodimers. Interacts with HSP70.
Subcellular Location : Cell membrane; Single-pass type II membrane protein. Secreted. Note=A secreted form also exists.
Tissue Specificity : Expressed at high level in endothelial cells and vascular-rich organs such as placenta, lung, liver and brain, aortic intima, bone marrow, spinal cord and substantia nigra. Also expressed at the surface of dendritic cells. Widely expressed at intermediate and low level.
Post-translational modifications : N-glycosylated.
DISEASE : Note=Independent association genetic studies have implicated OLR1 gene variants in myocardial infarction susceptibility.
