- Western blot analysis of Arginase 1 was performed by separating 50 µg of mouse tissue extract by 12% SDS-PAGE. Proteins were transferred to a membrane and probed with a Arginase 1 Polyclonal Antibody (Product # PA5-85267) at a dilution of 1:10000. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

- Knockout of Arginase 1 was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID CRIPSR760199_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of Arginase 1 was performed by loading 30 µg of Hep G2 Cas9 (Lane 1) and Hep G2 Arginase 1 KO (Lane 2) whole cell extracts. The samples were electrophoresed using NuPAGE™ Novex™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). 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-Arginase 1 Polyclonal Antibody (Product # PA5-85267, 1:2000 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:5000 dilution) using the iBright™ FL 1500 (Product # A44115). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). Loss of signal upon CRISPR mediated knockout (KO) using the LentiArray™ CRISPR product line confirms that antibody is specific to Arginase 1.

- Western blot was performed using Anti-Arginase 1 Polyclonal Antibody (Product # PA5-85267) and a 35kDa band corresponding to Arginase-1 was observed.. Tissue extracts (20 µg lysate) of Mouse Kidney (Lane 1), Rat Kidney (Lane 2), Mouse Liver (Lane 3) and Rat Liver (Lane 4) were electrophoresed using NuPAGE™ 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 the primary antibody (1:2000) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).Band of interest was observed only in Liver tissue and not in Kidney.

(b) The numbers of NOS 2 + cells. ** P = 0.0021 (WT versus KO, two-tailed t -test). (c) The difference in the M1/M2 ratio between the WT and CLU-KO groups was confirmed by the NOS 2 + /ARG 1 + ratio in each kidney. *** P = 0.0179 (WT versus KO, two-tailed t -test). Data in a , b and c are representative of three independent experiments and presented as the mean +- s.d. ( n = 3). (d) Representative images of three independent experiments.
