牽張顯微附屬設(shè)備
倒置,、正置即可
適用樣品：細(xì)胞或者組織（2D,、3D）
軸向：二維等邊軸、二維單軸向,、三維等邊軸,、三維單軸向、三維梯形牽張
牽張模式：真空動力抻拉培養(yǎng)板彈性柔性基底膜或3D水凝膠包埋的細(xì)胞
實時觀察：StageFlexer顯微附屬設(shè)備可在顯微鏡下觀察牽張作用下反應(yīng)
方便對照：可控制同一塊培養(yǎng)板部分孔細(xì)胞受力與否
多組牽張條件作用對照：可同時運行多個不同壓力大小,、不同頻率
不同加載周期程序,，方便多組牽張條件對比,；
軟件精準(zhǔn)調(diào)控：對牽張加載周期、張應(yīng)變大小,、頻率,、波形智能調(diào)控
牽張范圍：0 - 33%
牽張頻率：0.01- 5 Hz
細(xì)胞量大，便于后期分析：系統(tǒng)牽張傳導(dǎo)儀支持4塊6孔
（每孔1.2* 105個細(xì)胞）或24孔牽張板,，可同時兼容4個獨立
的FlexLink牽張加載傳導(dǎo)儀 ,，獨立操作四個不同的實驗程序
支持任何波形種類：如更好地控制在超低或超高應(yīng)力下形：

●彈性模量范圍1-80kPa

●可選多孔板、60mm和100mm培養(yǎng)板

●BioFlex® CellSoft標(biāo)準(zhǔn)6孔板

●在柔性基底上牽拉細(xì)胞

●腔室載玻片CellSoft

●表面蛋白包被,，無菌單獨包裝

CellSoft培養(yǎng)板有很多不同的種類,，如不同的硬度，不同的孔板,，用于顯微觀察的腔室載玻片（圓形多孔板）,，共價包被CollagenI或其他蛋白，可對細(xì)胞進(jìn)行靜態(tài)或動態(tài)牽拉應(yīng)力刺激,。更重要的一點,，新型的CellSoft培養(yǎng)板可以反復(fù)胰酶消化和再接種細(xì)胞，蛋白包被的表面可以重復(fù)使用多達(dá)三次,。

可以用標(biāo)準(zhǔn)或倒置顯微鏡進(jìn)行10-40倍觀察細(xì)胞牽張拉伸變化和反應(yīng)
