Western blot analysis was performed on nuclear enriched extracts (30 µg lysate) of HeLa (Lane 1), HCT 116 (Lane 2), HT-29 (Lane 3), A549 (Lane 4) and Hep G2 (Lane 5). The blot was probed with Anti-SRP20 Mouse Monoclonal Antibody (Product # 33-4200, 2 µg/ml) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjµgate (Product # A28177, 0.4 µg/ml, 1:2500 dilution). A ~25 kDa band corresponding to SRP20 was observed across the cell lines 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® 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 Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

SR proteins appear to be recruited from nuclear "speckles", in which they are concentrated, to sites of transcription in order to spatially coordinate transcription and pre-mRNA splicing within the cell nucleus.
