β-EP ELISA

β-EP ELISA在中國大陸努力搭建正牌細(xì)胞與國內(nèi)廣大科研人員之間的溝通橋梁。為您提供外,還有更多相關(guān)實驗產(chǎn)品,標(biāo)準(zhǔn)品,細(xì)胞株和實驗技術(shù)服務(wù)等等前期后續(xù)服務(wù)。選擇正確的實驗試劑或材料是實驗成功的關(guān)鍵。

 購買上海乾思生物細(xì)胞注意事項(乾思生物)發(fā)布

  一、客戶收到細(xì)胞先不開蓋,放在培養(yǎng)箱靜置若干小時后(看細(xì)胞密度而定)在倒置顯微鏡下觀察細(xì)胞生長情況,并對細(xì)胞進(jìn)行不同倍數(shù)拍照(建議受收細(xì)胞時的培養(yǎng)基拍一張照片,觀察培養(yǎng)基的顏色和是否有漏液情況,顯微鏡下拍細(xì)胞100X,200X各一張),排除細(xì)胞本身污染的情況;

  收到細(xì)胞未開封,出現(xiàn)污染狀況我們負(fù)責(zé)免費發(fā)送一株細(xì)胞。

  二、如為貼壁細(xì)胞,請在顯微鏡下觀察細(xì)胞密度:

  1. 未超過80%匯合度時,用75%酒精(建議配置75%酒精的水也是滅菌超純水,噴灑整個瓶消毒后放到超菌臺內(nèi),嚴(yán)格無菌操作;然后打開蓋子,先把培養(yǎng)基吸出10ml左右,放在離心管里,然后瓶口過火(嚴(yán)禁直接傾倒),這樣可以保證不污染,再用10ml的移液管,將剩余的培液全部吸出,放于離心管中,培養(yǎng)瓶中只剩余10ml左右培液就可以了。培養(yǎng)16hr(時間根據(jù)細(xì)胞生長情況調(diào)整)之后,傳代或者凍存。

  2. 超過80%匯合度時,請按細(xì)胞培養(yǎng)條件傳代培養(yǎng)。具體步驟如下:

  1) 棄去培養(yǎng)液,用3ml PBS(不含鈣,鎂離子)洗1-2次;

  2) 加1ml消化液(0.25%Trypsin-0.53mM EDTA)于T25培養(yǎng)瓶中,倒轉(zhuǎn)放于37度培養(yǎng)箱1-3分鐘預(yù)熱,然后又將培養(yǎng)瓶倒轉(zhuǎn)大約30秒后,在倒置顯微鏡下觀察細(xì)胞消化情況,若細(xì)胞大部分變圓分散,輕敲幾下培養(yǎng)培養(yǎng)瓶,細(xì)胞隨即脫落下來;

  3) 加入6-8ml*培養(yǎng)基,吸出,分到新的培養(yǎng)瓶中,按要求分瓶。

  三、如為懸浮細(xì)胞,吸出培養(yǎng)液,1000轉(zhuǎn)/分鐘離心5分鐘,吸出上清,管底細(xì)胞用新鮮培養(yǎng)基懸浮細(xì)胞后移回培養(yǎng)瓶。

  注意:換液時一半用我們的培養(yǎng)基,一半用你們的,以免細(xì)胞不適應(yīng)而造成生長不好。

  四、細(xì)胞出現(xiàn)問題,可重發(fā)的情況有哪些?判定標(biāo)準(zhǔn)是什么?

 ?。?)細(xì)胞運輸途中遭遇的各種問題,細(xì)胞丟失、破損、漏液等,重發(fā);

 ?。?)凍存的細(xì)胞復(fù)蘇后,絕大多數(shù)細(xì)胞未存活,重發(fā);

 ?。?)存活的細(xì)胞靜置24小時后,絕大多數(shù)細(xì)胞未存活,重發(fā);

  (4)凍存的細(xì)胞復(fù)蘇后或存活的細(xì)胞靜置4小時后并且未開封,出現(xiàn)污染,重發(fā);

  (5)視具體情況而定?!?/p>

  Acris abcam cst Biorbyt santa Novus sigma lifespan NEB roche ABI R&D millipore BD Qiagen Cayman Jackson Life GeneTex Bio-Rad DSHB tocris peprotech 等品牌;部分產(chǎn)品現(xiàn)貨,超低比價,另常備 Trizol DMSO lipo2000 lipo3000 SC-2004 SC-2005常備現(xiàn)貨 ;貨期短,價格優(yōu),售后齊全。

    細(xì)胞培養(yǎng)技術(shù)3個原則:1、用自己的一套試劑,不要和別人混用;2、勤觀察細(xì)胞,像養(yǎng)寵物一樣喜愛和關(guān)心;3、有規(guī)律地?fù)Q液和傳代,不要“三天打魚,兩天曬網(wǎng)”。
  質(zhì)量可靠,售后有保障

  ★我?guī)旒?xì)胞近3000種,來源于美國ATCC,細(xì)胞都是經(jīng)過嚴(yán)格質(zhì)量控制。

  凍存細(xì)胞時間為5-7個工作日,活細(xì)胞為7-15個工作日。

  ★由于細(xì)胞庫現(xiàn)有細(xì)胞類目多,為了不出現(xiàn)混亂錯誤,需要了解相關(guān)細(xì)胞價格及詳細(xì)資料請老師,對您造成的不便還請見諒!
