无酶细胞消化液不含蛋白消化酶,但能使贴壁细胞与培养瓶皿表面有效脱离达到分离细胞的目的。与常规胰蛋白酶消化方法相比,无酶细胞消化液作用温和,不损伤和破坏细胞,不影响细胞生物学特性,是肿瘤细胞在体移植实验的最佳细胞脱壁方法。细胞用无酶消化液脱壁后,可直接进行传代培养或离心收集用于其它实验。由于未使用蛋白酶制剂,因此特别适于收集细胞进行核蛋白和胞浆蛋白制备、WesternBlot、免疫共沉淀实验,同时能避免样品蛋白降解,并避免蛋白酶制剂中的RNA酶对RNA的降解。
产品特点:
1.室温孵育10分钟,贴壁细胞即可从瓶皿脱落,温和而有效。
2.脱壁的细胞可用于连续传代。
3.培养肿瘤细胞进行在体移植实验的最佳消化方法。
4.避免蛋白酶过度消化细胞及降解样品蛋白。
5.制备胞核和胞浆蛋白、进行Western Blot、免疫共沉淀。
6.避免蛋白酶制剂中污染的RNA酶降解RNA。
7.本品种含EDTA,不含胰酶。
使用说明:
1.用 PBS 洗涤单层培养细胞,尽可能完全去除瓶中液体。
2.加入适量无酶细胞消化液使其覆盖细胞表面,晃动瓶皿,使所有细胞均充分接触无酶消化液。
3.室温放置10分钟或适宜时间,偶尔晃动瓶皿,直到细胞完全脱壁。可加入细胞培养基或 2-3倍体积PBS缓冲液终止反应。脱壁后可能有成片细胞连在一起的现象,属于正常,如用作肿瘤移植,上述情况的产生可利于肿瘤细胞的生长。37℃时脱壁反应会加速。
4.500g 离心5-10 分钟,弃上清,收集细胞。
5.收集的细胞可用于:(1)胞核胞浆蛋白制备;(2)Westernblot;(3)免疫沉淀实验;(4)DNA蛋白结合实验;(5)RNA提取;(6)分瓶传代。
注意事项:
1. 本品禁止冻融,以免失效。
2.在使用细胞消化液的过程中,要特别注意避免消化液被细菌污染。
3.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。
4.为了您的安全和健康,请穿实验服并戴一次性手套操作。

This non-enzymatic cell detachment solution contains no proteolytic enzymes, yet effectively detaches adherent cells from the surface of culture flasks and dishes for cell isolation. Compared with conventional trypsin digestion, it acts mildly without damaging or altering cellular biological properties, making it the optimal cell dissociation reagent for in vivo tumor cell transplantation assays.After detachment with this solution, cells can be directly subcultured or harvested via centrifugation for downstream experiments. Free of protease additives, it is ideal for cell collection in nuclear & cytoplasmic protein extraction, Western Blot and co-immunoprecipitation assays. It prevents protein degradation in samples and avoids RNA breakdown induced by RNase contamination present in protease preparations.
Product Features
1. Adherent cells fully detach from culture vessels after 10 minutes of incubation at room temperature, delivering gentle yet efficient dissociation.
2. Dissociated cells support continuous serial subculture.
3. The preferred dissociation method for tumor cell culture prior to in vivo transplantation studies.
4. Eliminates excessive proteolytic damage to cells and sample protein degradation.
5. Suitable for nuclear/cytoplasmic protein extraction, Western Blot and co-immunoprecipitation.
6. Prevents RNA degradation caused by RNase contaminants in protease reagents.
7. Formulated with EDTA; trypsin-free.
Instructions for Use
1. Rinse the cell monolayer with PBS and aspirate all residual liquid thoroughly from the vessel.
2. Add an adequate volume of non-enzymatic cell detachment solution to fully cover the cell layer. Rock the flask/dish gently to ensure uniform contact between all cells and the reagent.
3. Incubate at room temperature for 10 minutes (or adjusted duration), rocking the vessel occasionally until complete cell detachment. Quench the reaction by adding complete culture medium or 2–3 volumes of PBS buffer. Clustered cell aggregates after detachment are normal; such aggregates actually promote tumor cell growth for transplantation applications. Dissociation proceeds faster at 37 °C.
4. Centrifuge the cell suspension at 500 g for 5–10 minutes, discard the supernatant and collect the cell pellet.
5. Harvested cells can be applied to the following experiments:
(1) Nuclear and cytoplasmic protein extraction
(2) Western Blot analysis
(3) Co-immunoprecipitation
(4) DNA-protein binding assays
(5) RNA isolation
(6) Cell splitting and subculture
Precautions
1. This product must not be freeze-thawed to prevent inactivation.
2. Strictly avoid bacterial contamination of the detachment solution during operation.
3. Do not over-digest cells; prolonged incubation will compromise post-seeding cell viability and growth.
4. Wear a lab coat and disposable gloves during manipulation for personal safety.
