Experimental details: Western blot was performed using Anti-TMEM173 (Product # PA5-23381 ) and a 38 kDa band corresponding to TMEM173 was observed. Whole cell extracts (30 µg lysate) of THP-1 (Lane 1), U-937 (Lane 2), HeLa (Lane 3), Jurkat (Lane 4) and K-562 (Lane 5) were electrophoresed using NuPAGE™ 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 the primary antibody (1:1000) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:20,000 using the iBright™ FL1500 Imaging System (Product # A44115). Chemiluminescent detection was performed using SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Product # 34580).

Experimental details: Knockdown of TMEM173 was achieved by transfecting THP-1 with TMEM173 specific siRNAs (Silencer® select Product # S50646, S50645). Western blot analysis (Fig. a) was performed using Whole cell extracts from the TMEM173 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with TMEM173 (Product # PA5-23381 , 1:3000 ) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:20,000). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to TMEM173.

Experimental details: Immunofluorescence analysis of TMEM173 was performed using 70% confluent log phase U-2 OS cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.01% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with TMEM173 (Product # PA5-23381 ) at 1:100 in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with Hoechst 33342 (Product # H1399). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image predominantly showing endoplasmic reticulum localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 40X magnification in CellInsight CX7 LZR High-Content Screening (HCS) Platform (Product # CX7C1115LZR). magnification.

Experimental details: Immunohistochemical analysis of STING in Human colon cancer tissue section. Samples were incubated in STING polyclonal antibody (Product # PA5-23381) using a dilution of 1:100 followed by HRP-conjugated secondary antibody. The signal was developed using DAB reagent and the nuclei were counterstained with hematoxylin. The antibody generated very weak cytoplasmic staining in columnar epithelial cells with a very strong signal in the secretory/goblet cells.
