GRK2 Antibody in Immunocytochemistry (ICC/IF) — Immunofluorescence analysis of GRK2 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with GRK2 Monoclonal Antibody (3F8) (Product # MA5-15840) at 1:250 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). 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 represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

GRK2 Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemical analysis of paraffin-embedded endometrial cancer tissues (left) and cervical cancer tissues (right) using GRK2 monoclonal antibody (Product # MA5-15840) followed with DAB staining.

GRK2 Antibody in Western Blot (WB) — Knockdown of GRK2 was achieved by transfecting HEK-293 cells with GRK2 specific siRNAs (Silencer® select Product # s1129). Western blot analysis (Fig. a) was performed using whole cell extracts from the GRK2 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with GRK2 Monoclonal Antibody (Product # MA5-15840, 1:2000 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25µg/ml, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to GRK2.

GRK2 Antibody — Antibody specificity was demonstrated by siRNA mediated knockdown of target protein. HEK-293 cells were transfected with GRK2 siRNA and reduction of signal was observed in Western Blot using GRK2 Monoclonal Antibody (Product # MA5-15840). {KD}

Product Specific Information

MA5-15840 targets GRK2 in IF, IHC, and WB applications and shows reactivity with Human, mouse, Non-human primate, and Rat samples.

The MA5-15840 immunogen is purified recombinant fragment of human GRK2 expressed in E. Coli. .

MA5-15840 detects GRK2 which has a predicted molecular weight of approximately 80kDa.

Target Information

G protein-coupled receptor kinases (GRKs) are important regulators of G protein-coupled receptors(GPCRs). GRK2 (83 kDa), one of six members of this family that have been identified, is ubiquitously expressed in mammals. After binding to their ligand and interacting with heterotrimeric G proteins, GPCRs (e.g., a2-adrenergic receptor) are phosphorylated by GRKs. Internalization of the GPCRs, regulated by beta-arrestin-1, leads to activation of the Ras - Raf - ERK1&2 signaling pathway. GRK2 activity is tightly controlled by different mechanisms including phosphorylation by kinases such as PKC, Src and ERK1&2, as well as interaction with various proteins. ERK phosphorylates and thus inactivates GRK2 on serine 670 in a negative feedback mechanism.
