NK cells, NK92 cells, and tumor tissues were lysed in Radio Immunoprecipitation
Assay (RIPA) buffer (Beijing Solarbio Science and Technology, China). Protein
samples was separated by 10% SDS-PAGE and transferred to polyvinylidene fluoride
membrane (Millipore, Bedford, MA, USA). The membrane was incubated with primary
Abs against RUNX3 (1:1000; Cell Signaling Technology, Danvers, MA, USA), NCR1
(1:500; Abcam, Cambridge, MA, USA) at 4°C overnight, and then incubated with
HRP-conjugated secondary Ab (Abcam, USA) at room temperature for 1 h. Bands were
visualized by an enhanced chemiluminescence reagent (Bio-Rad), and band
intensities were quantified using image software Image Lab (Bio-Rad). β-Actin
(Abcam) was used as an internal control.

Western Blot Analysis of VEGF Protein

Check if the same lab product or an alternative is used in the 5 most similar protocols
VEGF protein expression was detected using Western blotting. Proteins were extracted using Radioimmunoprecipitation assay (RIPA) buffer (Solarbio, China), which contained protease inhibitors. The Bicinchoninic acid assay (Beyotime, China) method was used to quantify the concentration of the collected proteins. The samples were electrophoresed on polyacrylamide gel and transferred to a polyvinylidene fluoride (PVDF) membrane. The membrane was blocked with 5% skim milk for 2h. Subsequently, the corresponding anti-VEGFA antibody (1:1000, Abcam, UK) was incubated at 4°C for 12 h. After washing with Tris-buffered saline with Tween solution (TBST), the membranes were incubated with the corresponding secondary antibody (ZSGB-BIO, China) for 1 h at room temperature. Images were visualized using a multicolor fluorescence imaging system (Amersham, UK). Grey level analysis was performed using the ImageJ software.

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.
