Experimental details

Western blot analysis was performed on Whole cell extracts and tissue extracts (30 µg lysate) of A549 (Lane 1), HeLa (Lane 2), Jurkat (Lane 3), U-87 MG (Lane 4), A-431 (Lane 5), MCF-7 (Lane 6), MOLT4 (Lane 7), Mouse Ovary (Lane 8) and MDA-MB-231 (Lane 9). The blots were probed with Anti-TPM4 (Tropomyosin 4) Rabbit Polyclonal Antibody (Product # 720311, 1-2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 28 kDa band corresponding to TPM4 was observed across the cell lines and tissues tested. Known quantity of protein samples were electrophoresed using Novex®NuPAGE®4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 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

For immunofluorescence analysis, HeLa cells were fixed and permeabilized for detection of endogenous Tropomyosin-4 using Anti- TPM-4 Rabbit Polyclonal Antibody (Product # 720311, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of TPM-4 protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c) represents cytoskeletal F-actin staining using Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating cytoskeletal localization of TPM-4. Panel e) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
