Experimental details: Western blot analysis was performed on whole cell extracts (30 µg lysate) of U-87MG (Lane 1), PC 3 (Lane 2) and HeLa (Lane 3). The blots were probed with Anti-Syntrophin Mouse Monoclonal Antibody (Product # MA1-745, 0.1-1 µg/mL) and detected by chemiluminescence Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 62-6520, 1:4000 dilution). A 60 kDa band corresponding to Syntrophin was observed across cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE®12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane by iBlot® 2 Dry Blotting System (Product # IB21001).The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Experimental details: Knockdown of Syntrophin was achieved by transfecting U87MG with Syntrophin specific siRNA (Silencer® select Product # s13261 and s13263). Western blot analysis was performed using whole cell lysates from the Syntrophin knock down cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-Syntrophin Mouse Monoclonal Antibody (Product # MA1-745, 0.1-1 µg/mL) and Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 62-6520, 1:4000 dilution). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to Syntrophin.

Experimental details: Immunofluorescence analysis of Syntrophin was done on 70% confluent log phase PC-3 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Syntrophin (1351) Mouse Monoclonal Antibody (Product # MA1-745) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Experimental details: Figure 10 WT/mdx muscle displays nNOS and dystrobrevin-alpha. Protein extracts from diaphragms of WT (lane 1), 10-30% WT/mdx (lane 2) and mdx (lane 3) mice were subjected to a western blot for dystrophin, nNOS, dystrobrevin-alpha, syntrophin and tubulin. *: dystrobrevin-alpha isoforms enriched in mdx and WT/mdx but not in WT muscle. Experiments were performed with pectoralis, diaphragm and quadriceps muscles of 3 animals (n = 3) per group (WT, 10-30% WT/mdx and mdx).

Experimental details: Figure 1 Generation and characterization of alpha-syntrophin mice. A, A targeting vector was constructed using a 7.4-kb Not I (N)/XbaI (X) restriction fragment long arm and a 1.5-kb XbaI fragment short arm. Homologous recombination resulted in the deletion of 2.8-kb of the alpha-syntrophin gene including all of exon 1. B, Southern blot analysis was performed using genomic DNA (isolated from ES cells or from mice) digested with EcoRI (E). Hybridization using the 500-bp probe shown in A, detected a 6.2-kb wild-type band and a 10-kb recombinant band. C, RNA blot analysis of poly A + RNA from the mice indicated. The positions of RNA standards are indicated. D, Immunoblot of muscle proteins partially purified with mAb 1351 and detected with alpha-syntrophin and beta1-syntrophin isoform specific antibodies. The position of a 59-kD protein standard is indicated on the left.
