Quantitative Analysis of Sodium New Houttuyfonate in HepG2 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sodium new houttuyfonate (SNH) was purchased from Xi'an Kailai Biological Engineering Co., Ltd. (Xi'an, China). We used high performance liquid chromatography to quantitatively analyze SNH with a purity of 98% (Fig. S1). HepG2 cells were obtained from ATCC. Dulbecco's Modified Eagle Medium (DMEM) was purchased from Gibco (USA). Fetal bovine serum (FBS), MTT, penicillin and streptomycin all were purchased from Sigma Chemical Co. (St. Louis, MO, USA). Annexin V-FITC/PI apoptosis detection kit, Apoptosis-Hoechst staining kit and DNA ladder extraction kit were from Shanghai Beyotime Biological Technology Co. Ltd. (Shanghai China). The primer of GADPH, MMP9, VEGF and Bcl-2 were synthesized by Shanghai Sangon Biological Engineering Technology and Service Company. One step RT-PCR kit was bought from Qiagen (Germany). All other reagents were of the highest grade commercially available.

Western Blot Analysis of EMT Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
The total proteins were extracted using a RIPA lysis system (Cat#: C500005, Sangon, China). Next, the proteins were separated with 10% SDS-PAGE gel and then transferred to PVDF membranes (Cat#: F019532, Sangon, China). After blocking the membranes in 5% skim milk, the hybridization membrane was incubated at 4 °C overnight with primary antibodies RBBP4 (Cat#: D154089, Sangon, China), Twist (Cat#: ab49254, Abcam, UK), Slug (Cat#: ab51772, Abcam, UK), Vimentin (Cat#: ab92547, Abcam, UK), MMP-2 (Cat#: ab92536, Abcam, UK) and GADPH (Cat#: D190090, Sangon, China). The membranes were then incubated with the corresponding secondary antibody for 2 h. Subsequently, the protein was detected using the ECL chemiluminescence kit (Cat#: C510043, Sangon, China) according to the manufacturer’s instructions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
