    Comments: HPAF-II is a human pancreatic adenocarcinoma cell line derived from peritoneal ascitic fluid of a 44 year old Caucasian male with primary pancreatic adenocarcinoma and metastases to the liver, diaphragm and lymph nodes. HPAF II is a spontaneous variant with unlimited replicative capability which proliferated from a static culture of HPAF-I cells.The cells express Muc 1 and Muc 4 mucin genes, and secrete high levels of Muc 1 mucin. They are pleomorphic and probably undergo some spontaneous differentiation in culture.
    Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
    Temperature: 37.0°C
    Subculturing: Protocol:
    1. Remove and discard culture medium.
    2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
    3. Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
      Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37�C to facilitate dispersal.
    4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
    5. Add appropriate aliquots of the cell suspension to new culture vessels.
    6. Incubate cultures at 37�C.

    Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:3 is recommended 
    Medium Renewal: 2 to 3 times per week
    Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5% 
    Storage temperature: liquid nitrogen vapor phase
    Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
    recommended serum:ATCC 30-2020

                          细胞基本技术
    (上海酶研发布)
    冻存细胞的复苏
    • 应遵守慢冻快融的原则。先将水浴锅调至37-37.5度,取出冻存的细胞迅速放入后将细胞面浸至水面以下不断摇动至融化。
    • 在无菌台内将完全培养基加入50ml的小培养瓶内,约5ml左右,然后用无菌吸管从冻存管内取出细胞,置培养并内轻轻摇晃,使细胞均匀后置培养箱内培养。
    传代:
    • 贴壁细胞:
    对于贴壁细胞应先吸(倒)尽培养基,吸的越干净越好,以免中和后加入的消化液,使强度减弱(或PBS洗1-3次)。50ml培养瓶加入消化液约1-3ml,按此比例进行消化,(根据经验),晃动使消化液铺均匀置37度培养箱约2-5分钟,镜下见细胞收缩变圆或少数脱落后,轻轻振动瓶底使细胞全部脱落,加入2-3ml完全培养基后,轻轻吹打,使细胞基本成单个悬浮,然后分置其它无菌培养瓶内,加入完全培养基后继续培养或实验。
    • 悬浮细胞:
    一般传代可直接将细胞原液分置其它培养瓶内,加入完全培养基继续培养,如要高浓度可先离心1000rpm,5min后加入完全培养基,轻轻吹匀后,分置其它培养瓶内加入完全培养基继续培养。

    冻存 

       将贴壁细胞消化后离心收集,悬浮细胞直接离心收集,以完全培养基或胎牛血清重悬细胞至终浓度约106/ml。加入10%的DMSO。以每管1~2ml分装至冻存管中。用绝热材料包裹置-70摄氏度冰箱冷冻过夜。次日保存到液氮中。 

         

    支原体污染及检测
      (1).支原体污染在细胞培养中Z常见、不易被查觉,但支原体污染可显著影响细胞功能干扰实验结果。支原体是介于细菌和病毒之间的目前所知能独立生活的Z小微生物,它无细胞壁,形态呈高度多形性,Z小直径0.2um,可通过滤器。
       
        支原体在污染细胞后,它通过影响细胞的DNA、RNA 的合成及急速消耗培养基中的氨基酸来YZ细胞的生长,并能降低细胞的融合率。因此,在运用各种细胞系进行实验研究时,首先要证明所用细胞有无支原体的污染。
          上海酶研生物细胞经过严格质控,不含有细菌、真菌、病毒(HIV、HBV、HCV)、支原体。


      (2).支原体污染后,培养基可不发生浑浊,细胞病变轻微或不明显,因此难以发现。目前,支原体检测的方法有以下几种。
     (a).相差显微镜观察;
      (b).低张处理地衣红染色法;
     (c).荧光染色法;
      (d).酶标法;
     (e).PCR法:基础医学细胞ZX使用该方法进行检测。
                   优点:灵敏度高,检测耗时短,样品量小
                  (只需50ul细胞培养用液上清)。
                  缺点:引物及制剂费用较高。
