- Description
- PA1-732 detects beta-Arrestin 2 in rat, human and bovine samples. PA1-732 has been successfully used in Western blot procedures. By Western blot, this antibody detects ~49 kDa and ~47 kDa proteins representing pan Arrestin in rat and bovine retina as well as rat brain samples. The PA1-732 immunogen is a synthetic peptide corresponding to residues C D(384) D I V F E D F A R L R L K(397) of human beta-arrestin 2. This peptide (Cat. # PEP-281) is available for use in neutralization and control experiments.

- Western blot analysis was performed on tissue enriched extracts (30µg lysate) of Mouse Brain (Lane 1) and Rat Spleen (Lane 2). The blots were probed with anti-beta-Arrestin 2 Rabbit Polyclonal Antibody (Product # PA1-732, 1:2000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25µg/mL, 1:4000 dilution). A 50 kDa band corresponding to beta-Arrestin 2 was observed across the tissues tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX), 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).

- Immunofluorescence analysis of beta-Arrestin 2 was performed using 70% confluent log phase HEK293 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 beta-Arrestin 2 Rabbit Polyclonal Antibody (Product # PA1-732) at 2µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

- Fig. 8 a beta-arrestin 2 before (CHF) and after LVAD therapy (CHF+LVAD) as compared to non-failing ventricles (NF). beta-arrestin 2 expression was determined by immunoblot (western blot) analysis and referred to a standard, respectively, whose densitometric value was set 1 by default. The value on the y -axis, therefore, reflects the percentage of each parameter's immunoblot band density in relation to this default value.

- Immunoprecipitation outputs used to assess JNK3-JIP1-beta-arrestin2-PSD95 colocalization in primary hippocampal neurons. ( A ) PSD95 was immunoprecipitated from the cell lysate homogenate using PSD95 antibody, and immune complexes were analyzed for the presence of JNK3, JIP1, and beta-arrestin2. Immunoprecipitation with IgG antibody was used as a control. ( B ) JNK3 was immunoprecipitated from the cell lysate homogenate using JNK3-specific antibody, separated by SDS-PAGE, and analyzed via Western blot with anti-PSD95, anti-JIP1, and anti-beta-arrestin2 antibodies. Immunoprecipitation with IgG antibody was used as a control. * indicates non-specific bands.

PSD95 was immunoprecipitated from the TIF using PSD95-specific antibody, separated by SDS-PAGE, and analyzed with Western blot with anti-PSD95, anti-JNK3 (mouse), and anti-JIP1 antibodies. Immunoprecipitation with IgG antibody was used as a control. ( C ) JNK3 was immunoprecipitated from the TIF using the JNK3 antibody, and immune complexes were analyzed for the presence of beta-arrestin2 and JNK3 (rabbit).
