【保存条件】 建议分装冻存,避免反复冻融,-20℃避光保存,有效期 1 年 【概述】 5×SDS-PAGE 双色蛋白上样缓冲液可保护蛋白质在样品制备步骤中免受热降解,并在SDS-PAGE 运行期间防止 pH 值变化。一些蛋白质对在 Tris 缓冲液中电泳期间温度波动引起的 pH 变化敏感,优化后的上样缓冲液组分可防止在 SDS-PAGE 电泳之前的样品加热过程中以及电泳过程中蛋白质降解。SDS 可与蛋白质结合使蛋白质-SDS 复合物上带有大量的负电荷,这时蛋白质本身的电荷完全被 SDS 掩盖,消除了各种蛋白质本身电荷的差异;SDS 还可以断开分子内和分子间的氢键,破坏蛋白质分子的二级和三级结构。DTT 可以断开半胱氨酸残基之间的二硫键,破坏蛋白质结构,消除了蛋白结构之间的差异。最终无电荷及结构上差异的蛋白(亚单位),电泳速度只是与其分子量大小有关。上样缓冲液包含两种跟踪染料:蓝色(溴酚蓝),用于跟踪电泳的进度;粉红色(pyroninY),用于在 Western 印迹过程中监测蛋白质向膜的转移。 【使用建议】 1. 室温或 37℃水浴解冻 5×SDS-PAGE 双色蛋白上样缓冲液,并摇晃混匀。2. 请按每 40μl 蛋白样品加入 10μl 上样缓冲液的比例(5 倍稀释)来使用。如果蛋白样品浓度过高,可用双蒸水稀释。3. 混匀后,100℃水浴加热 5-10 分钟,使蛋白变性。4. 冷却至室温后,10000-14000rpm 离心 2-5 分钟,取上清直接上样电泳即可【注意事项】 1. DTT 对人体有害,操作时请小心,并注意有效防护以避免直接接触人体或吸入体内。2. 该产品于-20℃保存时会出现 SDS 沉淀,使用前请确保溶液完全复溶混匀,有必要时可置于 37℃水浴促溶。3. 蛋白上样缓冲液含有溴酚蓝、吡罗红指示剂,PH 值受保存温度影响,在低温冻存状态下,溶液可能会呈现深棕色,不影响产品使用。4. 聚丙烯酰胺凝胶浓度为 8%时溴酚蓝指示条带的位置大概在 30kd 左右, 胶浓度为 12%时,约在 20kd 左右,胶浓度为 15%时,大概在 10kd。请根据自己目标条带来判断结果电泳时间。5. 一般而言,吡罗红的迁移速度快于溴酚蓝。在较高百分比的 SDS 聚丙烯酰胺凝胶(例如15%)中,吡罗红染料的迁移速度比溴酚蓝慢。6. 为了您的安全与健康,请穿实验服并戴一次性手套操作。

产品简介:胰酶细胞消化液(Trypsin-EDTA Solution)含 0.25%胰酶(Trypsin)和 0.02%EDTA,不含Ca2+和 Mg2+。该消化液已用 0.22 μm 滤膜过滤除菌,可以直接用于培养细胞的消化,或者一些组织的消化。本胰酶细胞消化液具有方便快速的特点,通常室温消化 1 分钟左右就可以消化下大多数贴壁细胞。使用说明:贴壁细胞的消化:1、吸去培养液,用无菌的 PBS、Hanks 液或无血清培养液洗涤细胞一次,以去除残余的血清。2、加入少量胰酶细胞消化液,略盖过细胞即可,室温放置 30 秒至 2 分钟。不同的细胞消化时间有所不同。3、显微镜下观察,细胞明显收缩,并且肉眼观察培养器皿底部发现细胞的形态发生明显的变化,或者用枪吹打细胞发现细胞刚好可以被吹打下来;此时吸除胰酶细胞消化液;加入含血清的完全细胞培养液,吹打下细胞,即可直接用于后续实验。4、如果发现消化不足,则加入胰酶细胞消化液重新消化。5、如果发现细胞消化时间过长,未及吹打细胞,细胞已经有部分直接从培养器皿底部脱落,直接用胰酶细胞培养液把细胞全部吹打下来。1000-2000g 离心 1 分钟,沉淀细胞,尽量去除胰酶细胞消化液后,加入含血清的完全培养液重新悬浮细胞,即可用于后续实验。 组织的消化:不同的组织需要消化的时间相差很大,通常以消化后可以充分打散组织为宜。注意事项:1、 在使用胰酶细胞消化液的过程中要特别注意避免消化液被细菌污染。2、 胰酶细胞消化液消化细胞时间不宜过长,否则细胞铺板后生长状况会较差。保存条件:4℃保存;长期贮存于-20℃中;-20℃贮存下保存一年。
