- Description
- PA1-725 detects transducin beta (T beta) from sheep, bovine, mouse and drosophila. PA1-725 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~37 kDa protein representing Tr beta from sheep and bovine retinal and optic nerve extracts as well as mouse eye samples and drosophila. The PA1-725 immunizing peptide corresponds to amino acid residues 8-25 from human Tr beta. This sequence is completely conserved between human, amphibian, bovine and rat. PA1-725 immunizing peptide (Cat. # PEP-154) is available for use in neutralization and control experiments.

- Western blot analysis was performed on membrane enriched cell extracts of Jurkat (Lane 1) and tissue lysate of Rat Brain (Lane 2). The blot was probed with Anti- Gnb1 Rabbit Polyclonal Antibody (Product # PA1-725, 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 37 kDa band corresponding to Gnb1 was observed across all lysates 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 Pierce™ ECL Western Blotting Substrate (Product # 32106).

- Western blot analysis was performed on whole cell extracts (30 µg lysate) of MCF7 (Lane 1), Jurkat (Lane 2), MADA-MB-231 (Lane 3), T-47D (Lane 4) and tissue extract of Rat Brain (Lane 5). The blot was probed with Anti-Gnb1 Polyclonal Antibody (Product # PA1-725, 1 µg/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A 37 kDa band corresponding to Gnb1 was observed across cell lines and tissue tested. Along with the band of interest a non-specific band at ~110 kDa was also observed.

- Western blot analysis of Gnb1 was performed by loading 30 ug of HeLa (Lane 1), HeLa - Gnb1 knockout (Lane 2) Edigene lysate. The blot was probed with Anti-Gnb1 Polyclonal Antibody (Product # PA1-725, 1 µg/ml) Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). Loss of signal upon CRISPR mediated knockout (KO) confirms that antibody is specific to Gnb1.

- Figure 5. Quantitative Western blotting of Pd-/- retinal extracts reveals decrease in transducin subunits expression. (A) Whole retinal extracts containing 100 fmol rhodopsin from WT and Pd-/- mice were separated on 10-20% polyacrylamide gels alongside 25, 50, 75, 100, 150 fmol purified transducin standard (1-5), and probed in Western blot analysis with antibodies against rod transducin subunits. (B) Fluorescence of the corresponding transducin standards bands from the top panel were plotted against the amounts of transducin in samples 1-5 (open circles), and fitted with sigmoid curves. Triangles represent the fluorescence of transducin bands from retina extracts. The number of determinations for each subunit is indicated in Table II .
