Immunofluorescence Staining of WTAP and BCL6 in OCI-Ly10 Cells

After cultures with PU-H71 or DMSO for 48 h, OCI-Ly10 cells were washed twice in PBS, spread onto slides, air dried and fixed in acetone at − 20 °C for 15 min. Immunofluorescence staining was performed as described previously [13 (link)]. After treatment of 0.3% Triton X-100 (KeyGen Biotech) for 10 min, the slides were blocked with Goat serum (Boster Biological Technology) for 1 h at room temperature. The cells were then incubated with the primary antibody against WTAP (diluted 1:50, Santa Cruz, sc-374280) and BCL6 (diluted 1:100, Abcam, ab33901) overnight at 4 °C. Signals were detected with Alexa Fluor 488 and Alexa Fluor 594, respectively. Nuclei in live cells were stained with 4', 6-diamidino-2-phenylindole (DAPI), and visualized with laser confocal microscopy (NikonA1R).

Each sample used 100 µl Protein-G DYNA beads blocked over night at 4 °C in 500 µl of IP lysis buffer (50 mM HEPES-NaOH pH 7.5, 100 mM NaCl, 1 mM EDTA pH 8.0, 0.1% Triton X-100, 10% Glycerol, 1 mM DTT) containing 1% BSA and 2–10 µg of antibody. Beads were subsequently washed 3 times in 1 ml IP lysis buffer. Cells were washed with PBS before lysis in IP lysis buffer containing protease inhibitor, DNase 1, RNase A and DTT. Extracts were cleared by centrifugation at 13 200 rpm, 5 minutes at 4 °C. Cell extracts were incubated with antibody bound beads for 2 hours at 4 °C. Beads were washed 3 times in 1 ml ice cold IP lysis buffer. After the final wash beads were resuspend in 72 µl 1 M Arginine-HCl pH 3.5, incubated for 1 minute on ice and spun for 1 minute at 400 × g. Eluate was transferred to a fresh 1.5 ml tube and neutralised with 3 µl 1.5 M Tris.HCl (pH 8.8) prior to SDS-PAGE. Antibodies used in this study were: FLAG – Sigma F3165, WTAP Santa Cruz sc-374280 (used for Fig. 1A), WTAP Abcam Ab195380 used for remaining Figures, KIAA1429 – Proteintech 25712-1-AP, METTL3 – Proteintech 15073-1-AP, HNRNPA1 – Millipore 04-1469, METTL14 – Sigma HPA038002, ACTIN – Sigma A5060, YTHDC1 – Proteintech 14392-1-AP, SSRP1 – Biolegend 609701, TUBULIN – Sigma T5168, ALYREF – Abcam Ab6141, NXF1 – Abcam Ab50609, DDX39A/B and THOC5 were described previously3 (link).

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.
