Experimental details: Peptide Competition. Extracts prepared from HEK 293 cells treated with UV irradiation were resolved on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4°C, then were incubated with p38 (pTpY180/182) antibody for two hours at room temperature in a 3% BSA-TBST buffer, following its prior incubation with: the peptide immunogen (1), a generic phosphothreonine-containing peptide (2), a generic phosphotyrosine-containing peptide (3), the non-phosphorylated peptide corresponding to the phosphopeptide (4), no peptide (5), the phosphopeptide derived from the corresponding region of JNK1&2 (6), and, the phosphopeptide derived from the corresponding region of ERK1&2 (7). After washing, membranes were incubated with goat F (ab')2 anti-rabbit IgG HRP conjugate (Product # ALI4404) and bands were detected using the Pierce SuperSignal™ method. The data show that only the phosphopeptide corresponding to p38 (pTpY180/182) blocks the antibody signal, thereby demonstrating the specificity of the antibody.

Experimental details: CRISPR-Cas9 mediated genome editing ofp38 (as confirmed by next generation sequencing) was achieved by using LentiArray™ Lentiviral sgRNA (Product # A32042, AssayID) and LentiArray Cas9 Lentivirus (Product # A32064). Fig (a) Western blot analysis of p38 was performed by loading 60 µg of HeLa Cas9 (Lane 1), HeLa Cas9 treated with UV for 40 minutes (Lane 2), HeLa Cas9 cells transduced with p38 Lentiviral sgRNA (Lane 3), and HeLa Cas9 cells transduced with p38 Lentiviral sgRNA treated with UV for 40 minutes cells transduced with p38 Lentiviral sgRNA (Lane 4) whole cell extracts. The samples were electrophoresed using NuPAGE™ Novex™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with Anti-Phospho-p38 MAPK (Thr180, Tyr182) Polyclonal Antibody (Product # 44-684G, 1:1000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036 1:10,000 dilution).Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076). A loss of signal in sgRNA transduced cells using the LentiArray™ CRISPR product line confirms that antibody is specific top38.

Experimental details: p38 (pTpY180/182) phosphospecific antibody. RAW cells were untreated (-) or treated (+) with Anisomycin. Two-color In-Cell Western was performed on the LI-COR Odyssey® Infrared Imaging System using actin, p38 (pTpY180/182) (Product # 44-684G), and JNK1/2 (pTpY183/185) (Product # 44-682G) antibodies. Two spectrally distinct dyes were used to detect actin (green, 800 nm channel), p38 (pTpY180/182) or JNK1/2 (pTpY183/185) (red, 700 nm channel), or a composite of both (yellow).

To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a p38 (pTpY180/182) polyclonal antibody (Product # 44-684G) diluted in 3% BSA-PBS at a dilution of 1:100 overnight at 4ºC in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Experimental details: Flow cytometry analysis of p38 [pTpY180/182] was done on K562 cells treated with anisomycin (25ug/mL, 30 minutes). Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with p38 [pTpY180/182] Rabbit Polyclonal Antibody (44684G, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Experimental details: Figure 5 MKP-2 deletion enhances M-CSF-mediated ERK phosphorylation in macrophages. Cells harvested on day 3 of culture, were rendered quiescent in M-CSF free medium then stimulated with recombinant M-CSF (10 ng/mL) for the times indicated. Control cells (0) were left untreated. Whole cell lysates were prepared, and assessed for ( A ) MKP-2 (43 kDa) ( B ) p-ERK (42/44 kDa), ( C ) p-JNK (46/65 kDa), and ( D ) p-p38 (38 kDa) or total controls by Western blotting, as described in the Methods. MKP-2 was not induced in cells that were derived from MKP-2 -/- mice (upper left insert of Panel A). Blots were semi-quantified for fold stimulation by scanning densitometry relative to the background signal. The blot represents the data from 2-3 individual experiments. * p < 0.05, one-tailed unpaired t test comparing MKP-2 -/- to MKP-2 +/+ macrophages.
