Check if the same lab product or an alternative is used in the 5 most similar protocols
Tissue sections of xenograft tumors in nude mice and the same bladder cancer TMAs used in CISH staining were analyzed in this study. TMA was obtained from Xinchao Biotech, Shanghai, China. All the paraffin tissue sections were dewaxed and rehydrated. Antigen retrieval was performed by heating the slides in sodium citrate buffer (10 mM, pH 6.0). After blocking with bovine serum albumin (Sango Biotech, Shanghai, China), the slides were incubated with anti-Ki-67 (Cell Signaling Technology, Beverly, MA, USA), or anti-FLOT1 (Epitomics, Burlingame, CA, USA) overnight at 4 °C. The slides were then incubated with a secondary antibody of goat anti-rabbit HRP conjugate (Cell Signaling Technology, Beverly, MA, USA) for 1 h at room temperature. A DAB solution was used for brown color development. The strength of positivity was semi-quantified by considering both the intensity and proportion of positive cells.

Protein was extracted from cells or tissues using T-per tissue protein extraction reagent (catalog #78510) lysis buffer. Concentration was measured using the Bradford Assay reagent. 10-40 ug of protein was loaded on SDS-polyacrylamide gel and transferred to a nitrocellulose membrane. The membrane was blotted with anti-Mettl3 (#ab195352 Abcam, #MA5-27527 Invitrogen), anti-Mettl14 (#HPA038002, Sigma), anti-GFP (#GFP-1020 Aves Lab), anti-HA (#3724, Cell Signaling), anti-c-Myc (#ab185656 Abcam, #OP10-200ug Sigma), anti-Avpr2 (#AB1797P, EMD Millipore), anti-Yap1 (#4912, Cell Signaling), anti-pCREB (#9198S, pCreb1), anti-PCNA (#sc-7907, Santa Cruz), or anti-puromycin (#PMY-2A4, Developmental Studies Hybridoma Bank) antibodies. All the primary antibodies were used at 1:1000 dilution, except for anti-puromycin, which was used at 1:50 dilution. Goat anti-rabbit-HRP conjugate (#7074S, Cell Signaling) or anti-mouse HRP-conjugated IgG (#7076S, Cell Signaling) was used as the secondary antibody. HRP-conjugated Actin antibody (#A3865, Sigma) was used at 1:40,000 dilution for measuring total protein. The blots were developed using the X-ray film developer or the Bio-rad digital imager. The protein bands were quantified using the Imagelab software from Bio-rad. Each western blot was repeated at least three times.

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.
