产品描述


glycotech 31-001,31-010细胞流体剪切应力培养腔室,Flow Chamber Kit (Parallel Plate)-现货

  • (Parallel-Plate Flow Chamber)
  • 描 述:
  • 平行板流动小室(Parallel-Plate Flow Chamber)是体外研究细胞力学*常用的模型之一,用来模拟体内各种细胞处于生理环境中,暴露在动态液体流作用下所受到的流体剪应力。体外细胞的代谢反应与所受到的壁面剪应力密切相关。
  • 典型的平行板流动小室由三个部分组成:聚碳酸酯分液室,硅胶垫圈和玻璃盖玻片。分液室构成流动小室的一侧,包括进液口,出液口和真空槽。垫圈的厚度决定流程长度。盖玻片构成流动小室的另一侧,其上覆盖细胞外基质蛋白(ECM),血管细胞或其他待研究的生物材料。真空形成一个密封环境将三个部件紧密连接在一起,同时也确保通道高度的一致性。
  • 优 势:
  • 1.平行板流动小室能够产生生理学范畴内的壁面剪应力:0.01-30 dyn/cm2。通过注射泵以可控的运动力将液体(如抗凝的全血或者细胞悬液)注入小室并流进固定化基质的方法产生剪应力。
  • 2.装置设计,组装和操作简单,方便;
  • 3.可以在设定的时间-周期内研究稳定剪应力对细胞的影响;也可以随实验需求调节流速和剪应力;
  • 细胞可在流动条件下生长,能够在显微镜下随时观察生长状态;或者利用视频显微镜实时监控细胞状态;
  • 应 用:
  • 1.模拟体内血液流动产生的血流剪切力,研究不同剪应力下白细胞和内皮细胞之间的动态粘附作用或白细胞受体-配体间的相互作用等;
  • 2.利用平行板流动小室产生剪应力模拟肿瘤细胞的体内生长环境,从而研究肿瘤细胞的增殖,吸附和转移机制。
  • 3.细胞趋化实验中作为**测试体系,基于白细胞-内皮细胞粘附过程作为新**的运输体系;
  • 产品介绍:
  • Glycotech公司提供两种平行板流动小室:Rectangular Flow Chamber(矩形流动小室)和Circular Flow Chamber(圆形流动小室),含有平行流动小室装置需要的基本组成部件。客户根据自身实验需求选择合适的产品。

  • Flow assays allow visualization of cell adhesion under well-defined wall shear stress. The visualization of the different events of cell adhesion can be quantified by selective image acquisition and subsequent image processing. Flow assays are uniquely suited to the investigation of adhesive events which occur very rapidly in a time scale shorter than that of most static adhesion assays. In addition, events subsequent to the initial events can be studied such as cell stabilization and spreading giving some insight into the kinetics of particular cell-cell or cell-substrate adhesive behavior.

    Microscopy:
  • Inverted-stage microscope configured for phase contrast and fluorescence operation
  • Objective lens (6.3 x, 10 x, 40 x)
  • Stage incubator

  • Cell monolayer or coated substrate in 35 mm dishes
  • Adhesion media (culture media serum-free with 12 mM Hepes)
  • Fibronectin (human plasma)
  • Bovine serum albumin (BSA)
  • Flow Chamber System:

  • Protocol:

  • Cell Monolayer Preparation
  • 1. Coat dishes with human fibronectin (FN) by adding 1 ml of 5.5?g/ml FN solution to each dish.
  • 2. Incubate for 30 min. at room temperature.
  • 3. Aspirate solution out of each dish.
  • 4. Add 2 ml of cell suspension (Huvecs, CHO cells) to each dish at seeding density of 0.5-3.0 x 105 cells/ml depending on time required to reach confluence.
  • 5. After 1-5 days, use dishes with confluent monolayer in flow assay. Feed cells every 2-3 days, but usually not with 48 hrs. of flow assay.
  • Coated Substrate Preparation
  • 1. Outline a coating region (5 mm diameter) for coating substrate in the center of each dish with marking pen.
  • 2. Add 20?l of solution containing substrate at a concentration of 10?g/ml to coating region. Incubate 1 hr.
  • 3. Aspirate off liquid, add 20?l of 1% BSA to block for 1 hr.
  • 4. Aspirate off BSA, add 20?l of inhibitor for 1 hr.
  • 5. Dishes are ready for use in flow assay.
  • Flow Assay Using Parallel Plate Flow Chamber
  • 1. Turn on stage incubator and warm adhesion media to 37?C 1 hr. prior to beginning flow assay.
  • 2. Assemble flow system apparatus connecting inlet, outlet, and vacuum lines to the flow chamber deck. Fill system with media and remove all air from system.
  • 3. Fill inlet reservoir with cell suspension. For assays using cell monolayers, 106 cells/ml is recommended. For coated substrate assays, use 105 cells/ml.
  • 4. Attach dish to flow chamber deck by holding the deck inverted, place a small bubble of media on flow path area, then place 35 mm dish on the deck. Vacuum will hold dish on deck. Make sure dish was attached with no air bubbles in the flow path.
  • 5. Place assembled chamber on microscope stage.
  • 6. Initiate flow of cells syringe pump connected to outlet flow chamber at a shear stress in the range of 0.1-4.0 dynes/cm2.
  • 7. Allow cells to flow for sufficient time to get an adequate number of cells interacting with the cell monolayer or coated surface. Generally 3-10 min. is used.
  • 8. Begin image acquisition. Collect images at 7-10 locations on the dish. Generally 3 dishes at a given experimental condition gives enough data to show statistical differences between treatments.
  • 9. After images are acquired on all dishes, perform image analysis to quantify the flow assay.
