Total protein was extracted via RIPA lysis (Beyotime, Shanghai, China) with phenyl-methane-sulfonyl fluoride and protease inhibitor. 10% SDS-PAGE gel electrophoresis with 30 μg protein per well was performed and then we transferred PVDF membranes. Antibodies PRPF6 (No. ab99292, 1:2000, Abcam, London, England), CEBPB (No. ab32358, 1:2000, Abcam, London, England), GATA3 (No. ab199428, 1:2000, Abcam, London, England), Vimentin (No. ab40497, 1:1000, Elabscience, Wuhan, China), E-cadherin (No. ab40285, 1:1000, Elabscience, Wuhan, China), N-cadherin (No. ab70061, 1:1000, Elabscience, Wuhan, China), β-tubulin III (No. YM0634, 1:2000, Immunoway, Wuhan, China), β-actin (No. AP0060, 1:5000, Bioworld, Wuhan, China) were incubated overnight at 4°C.

Magna RIP-Seq Profiling of SNHG16

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experiment was conducted followed the manufacturer’s protocol of Magna RIP Kit (Millipore, Massachusetts, USA). The antibodies were PRPF6 (10 ug per reaction, Abcam, London, England) and CEBPB (10 ug per reaction, Abcam, London, England). RNA was extracted after detachment from the bead using protease K. The expression of SNHG16 pre-mRNA, SNHG16-L and SNHG16-S was determined using RT-qPCR.

Cells growing on coverslips in 6-well plates were removed and fixed with 4% paraformaldehyde. Then, permeabilized in 0.5%–1.0% Triton X-100 for 10 min and blocked with 5% BSA for 30 min. The cells were then incubated with antibodies PRPF6 (1:150, Abcam, London, England), CEBPB (1:150, Abcam, London, England), GATA3 (1:150, Abcam, London, England) overnight at 4°C. Fluorescent-labelled secondary antibody (1:100, Proteintech, Wuhan, China) was added and incubated in the dark for 2 h. Cells were stained with DAPI and observed under the fluorescent microscope.

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.
