5× 萤火虫裂解缓冲液是一种浓缩的细胞裂解缓冲液,专为萤火虫荧光素酶检测试剂盒(F598310 和 F773892)设计使用。这些试剂盒配备了足量的 5× 萤火虫裂解缓冲液,可满足在 96 孔 - 24 孔板中培养的细胞进行规定次数的检测。当需要更多裂解缓冲液(如每孔>100 微升)时,5X 萤火虫裂解缓冲液可单独购买,用于配合这些试剂盒使用。
注意:5× 萤火虫裂解缓冲液与海肾荧光素酶不兼容。如果需要额外的裂解缓冲液用于海肾荧光素酶检测试剂盒(R598308)以及萤火虫和海肾荧光素酶检测试剂盒(D829607,请订购 5× 被动裂解缓冲液(P1375510)。
操作步骤
细胞裂解物的制备
1. 将 1 体积的 5× 萤火虫荧光素酶裂解缓冲液加入 4 体积的蒸馏水(dH₂O)中,充分混合,制备成 1× 裂解缓冲液。1× 裂解缓冲液可在 4℃下储存,最长达 1 个月。
多孔板中培养细胞的裂解
1.移除培养细胞的生长培养基,轻轻加入足量的磷酸盐缓冲盐水(PBS)冲洗培养容器表面。按以下推荐体积向每种培养板的各孔中加入 1× 裂解缓冲液:
|
2. 将培养板置于摇床或轨道摇床上,轻轻摇晃,确保 1× 裂解缓冲液完全且均匀地覆盖细胞单层。在室温下摇晃培养板 15 分钟。注意:过度生长的培养物通常更难完全裂解,通常需要增加裂解缓冲液的体积和 / 或延长处理时间,以确保完全裂解。将细胞从培养板上剥离会有助于细胞裂解过程。
3. 将裂解物转移至试管或小瓶中。可选步骤:可将裂解物在冷藏微量离心机中以最高转速离心 30 秒,取上清转移至新试管中。置于 4℃下直至准备检测。若当天不进行检测,可将裂解物储存在 - 20℃或 - 70℃。
4. 如需使用萤火虫荧光素酶检测试剂盒(F598310 或 F773892)检测裂解物,请遵循试剂盒随附的检测操作规程。
5× Firefly Lysis Buffer is a concentrated cell lysis buffer that is designed for use with Firefly Luciferase Assay Kit (F598310 and F773892).These kits are supplied with sufficient 5X Firefly Lysis Buffer to perform the stated number of assays with cells grown in 96 – 24 well plates. 5× Firefly Lysis Buffer is sold separately for use with the kits when more lysis buffer (e.g. >100 uL/well) is required.
Note: 5× Firefly Lysis Buffer is not compatible with Renilla Luciferase. If you require additional lysis buffer for use with Renilla Luciferase Assay Kit (R598308) and Firefly and Renilla Luciferase Assay Kit (D829607), order 5× Passive Lysis Buffer (P1375510).
Protocol
Preparation of cell lysates
1. Prepare 1× lysis buffer by adding 1 volume of 5× Firefly Luciferase Lysis Buffer to 4 volumes of dH2O and mixing well. 1× lysis buffer may be stored at 4°C for up to one month.
Lysis of Cells Cultured in Multiwell Plates
1. Remove growth medium from cultured cells and gently add a sufficient volume of phosphate buffered saline (PBS) to wash the surface of the culture vessel. Add 1× lysis buffer to each well using the volume recommended below for each type of culture plate:
|
2. Place the culture plates on a rocking platform or orbital shaker with gentle rocking/shaking to ensure complete and even coverage of the cell monolayer with 1× lysis buffer. Rock the culture plates at room temperature for 15 minutes. Note: Cultures that are overgrown are often more resistant to complete lysis and typically require an increased volume of lysis buffer and/or an extended treatment period to ensure complete lysis. Lifting cells from the plate will facilitate the process of cell lysis.
3. Transfer the lysate to a tube or vial. Optional: the lysate can be cleared by centrifugation for 30 seconds at top speed in a refrigerated microcentrifuge and transferred into a new tube. Place at 4°C for until ready to assay. Store lysates at -20°C or -70°C if assay will not be performed on the same day.
4. To assay lysates with Firefly Luciferase Assay Kit (F598310 or F773892), follow the assay protocols provided with the kit.
