Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.

Immunoprecipitation: This antibody can be used to immunoprecipitate GRK2/3 from transfected cells. Western Blot: 0.1-1ug/ml. Detects GRK2/3 in RIPA lysates from mouse 3T3 fibroblasts. Previous lots of this antibody detected GRK2/3 in bovine brain cytosol preparation, rat L6 myoblasts, human A431 carcinoma and human HeLa cell RIPA lysates. 3T3 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with G8972 (0.1ug/ml). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system.

F4209: Fibroblast Cell, 3T3/A31. Add 2.5ul of 2-mercaptoethanol/100ul of lysate and boil for 5 minutes to reduce the preparation. Load 20ug of reduced lysate per lane for minigels.

May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Note: Applications are based on unconjugated antibody.

Partial GST fusion protein corresponding to the GRK3 (bARK2) carboxyl terminus (aa 467-688). This immunogen shares homology with GRK2 (bARK1). The minimal epitope recognized by the antibody is aa 483-485.

Supplied as a liquid in PBS, pH 7.2. No preservative added. Labeled with MaxLight™550.

Purified by Protein G affinity chromatography.

Recognizes human GRK2/3 at ~80 kD. Additional bands at 85 and 50 kDa are also detected when using higher concentrations of the antibody. Epitope maps to aa483-485. Species Crossreactivity: rat, mouse, chicken, bovine, porcine and rabbit.
