| C0009 | MTT细胞增殖及细胞毒性检测试剂盒 | 500次 | 246.00元 |
MTT细胞增殖及细胞毒性检测试剂盒(MTT Cell Proliferation and Cytotoxicity Assay Kit)被广泛应用于细胞增殖和细胞毒性的检测。MTT可以被线粒体内的一些脱氢酶还原生成结晶状的深紫色产物formazan。在特定溶剂存在的情况下，可以被完全溶解。然后通过酶标仪可以测定570nm波长附近的吸光度。细胞增殖越多越快，则吸光度越高；细胞毒性越大，则吸光度越低。
本试剂盒采用了独特的Formazan溶解液配方，无需去除原有的培养液，可以直接加入Formazan溶解液溶解formazan。从而避免了由于去除培养液时formazan被部分去除而引起的误差。
本试剂盒本底低，灵敏度高，线性范围宽，使用方便。

本试剂盒可以测定500个样品。

保存条件：
4℃或-20℃保存，MTT需避光保存，一年有效；MTT配制成溶液后需-20℃避光保存；Formazan溶解液也可以室温保存。
注意事项：
由于使用96孔板进行检测，如果细胞培养时间较长，一定要注意蒸发的问题。一方面，由于96孔板周围一圈最容易蒸发，可以采取弃用周围一圈的办法，改加PBS，水或培养液；另一方面，可以把96孔板置于靠近培养箱内水源的地方，以缓解蒸发。
MTT溶剂在低温情况下会凝固，使用前请室温放置或20-25℃水浴温育片刻至全部融解后使用。
MTT配制成溶液后为黄色，需避光保存，长时间光照会导致失效。当颜色变为灰绿色时，请勿使用。MTT溶液在4℃、冰浴等较低温度情况下会凝固，可以20-25℃水浴温育片刻至全部融解后使用。
Formazan溶解液结冻或产生沉淀时可以37℃水浴孵育以促进溶解，并且必须在全部溶解并混匀后使用。
为了您的安全和健康，请穿实验服并戴一次性手套操作。
使用说明
使用说明：
1. MTT溶液的配制：用5ml MTT溶剂溶解25mg MTT，配制成5mg/ml的MTT溶液。配制后即可使用，或直接
-20℃避光保存，也可以根据需要适当分装后-20℃避光保存。
2. 通常细胞增殖实验每孔加入100微升2000个细胞，细胞毒性实验每孔加入100微升5000个细胞(具体每孔所
用的细胞的数目，需根据细胞的大小，细胞增殖速度的快慢等决定)。按照实验需要，进行培养并给予
0-10微升特定的药物刺激。
3. 每孔加入10微升MTT溶液，在细胞培养箱内继续孵育4小时。
4. 每孔加入100微升Formanzan溶解液，在细胞培养箱内再继续孵育。直至在普通光学显微镜下观察发现
formazan全部溶解。通常37℃孵育4小时左右，紫色结晶会全部溶解。如果紫色结晶较小较少，溶解的时
间会短一些。如果紫色结晶较大较多，溶解的时间会长一些。
5. 在570nm测定吸光度。如无570nm滤光片，可以使用560-600nm的滤光片。
