Experimental details: Immunofluorescent analysis of PAX5 (green) showing staining in the in the nucleus of Ramos cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a PAX5 polyclonal antibody (Product # PA1-109) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark.Nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

Experimental details: Immunofluorescent analysis of PAX5 (green) in Ramos and negative control Jurkat cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were blocked with 2% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed with a PAX5 polyclonal antibody (Product # PA1-109) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-rabbit IgG secondary antibody (Product # 35552) at a dilution of 1:200 for 30 minutes at room temperature. F-Actin (red) was stained with DyLight-554 Phalloidin (Product # 21834) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

Experimental details: Flow cytometry analysis of PAX5 (red histogram) on Ramos cells. Cells were harvested, fixed with 4% formaldehyde, permeabilized, washed with PBS, and incubated with a PAX5 polyclonal antibody (Product # PA1-109) at a 1:50 dilution or with PBS alone (black histogram) for 1 hour at room temperature. For flow cytometry analysis, 30-minute incubation with DyLight 488 goat anti-rabbit IgG secondary antibody (Product # 35552) was performed. 30,000 cells were acquired for analysis.

Experimental details: Immunoprecipitation of PAX5 was performed using Raji whole cell lysates. Antigen-antibody complexes were formed by incubating 750 µg of lysate with 5 µg of a PAX5 polyclonal antibody (Product # PA1-109) overnight on a rocking platform at 4øC. The immune complexes were captured on 50 µL Protein A/G Agarose (Product # 20421), washed extensively, and eluted with 5X Lane Marker Reducing Sample Buffer (Product # 39000). Samples was resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween-20 for 1 hour. The membrane was probed with a PAX5 polyclonal antibody (Product # PA1-109) at a dilution of 1:1000 overnight rotating at 4øC. Membranes were washed in TBST, and probed with Clean-Blot IP Detection Reagent (Product # 21230) at a dilution of 1:1000 for at least one hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080).

Experimental details: Figure 4 CTS Promotes the Expression of miR-106a-5p through the Recruitment of PAX5 to the Promoter of miR-106a-5p (A) Luciferase activity of different miR-106a-5p promoter constructs in cultured human chondrocytes with or without CTS stimulation. P1, promoter (-186 bp); P2, promoter (-439 bp); P3, promoter (-761 bp); P4, promoter (-1,000 bp); P5, mutated promoter (-761 bp). (B) Luciferase assay in cultured human chondrocytes infected with FLAG-tagged IRF2 or PAX5 or STAT4 and P5. Immunoblot shows the expression of IRF2, PAX5, and STAT4 with anti-FLAG. (C and D) Cultured human chondrocytes were infected with the PAX5 plasmid (C) and the vector control or shRNA for PAX5 (D), followed by stimulation with CTS as described in the Methods section. Immunoblot indicates the expression of PAX5. (E) Chromatin immunoprecipitation (ChIP) assay for PAX5 occupancy on the miR-106a-5p promoter or upstream of the promoter in cultured human chondrocytes. Each bar represents the mean +- SD of at least three independent experiments performed in triplicate. *p < 0.05, **p < 0.01.
