Lanes 2, 4, 6, 8 and 10 contain autophosphorylated (+) brain cytosolic protein in the amounts shown; lanes 3, 5, 7, 9 and 11 contain nonphosphorylated (–) brain cytosolic protein in the amounts shown. The presence of the autophosphorylated CaM KII was detected using the Anti-ACTIVE® CaM KII pAb diluted 1:5,000. Immunocytochemical staining of Akt in embryonic rat brain cells. Embryonic (day 17) rat brain cells were collected and treated with 20ng/ml each of EGF and FGF. Anti-pS473 Akt pAb was used at a 1:50 dilution. Positive cells were visualized using a donkey anti-rabbit, Cy®3conjugated secondary antibody. Nuclei were stained using DAPI. Protocols developed and performed at Promega. A. 1 2 B. 1 2 – Phospho-Akt – Akt Detection of phosphorylated Akt by Western blot analysis with AntipS473 Akt pAb. Panel A. NIH/3T3 total cell extract (10μg per lane) was resolved by polyacrylamide gel electrophoresis and blotted onto nitrocellulose. Lane 1, untreated cells; lane 2, cells pretreated with PDGF (Invitrogen) at 50ng/ml for 20 minutes. Anti-pS473 Akt pAb (Cat.# G7441) was used at a 1:2,500 dilution. The blot was probed with Donkey Anti-Rabbit IgG (H + L), HRP, Anti-ACTIVE® Qualified pAb (Cat.# V7951) at 1:10,000 dilution followed by chemiluminescent detection. Panel B. A pan-Akt pAb (New England Biolabs) reveals total Akt in both stimulated and unstimulated NIH/3T3 cell extracts. Secondary antibody and detection methods were the same as those used in Panel A. Immunocytochemical detection of autophosphorylated CaM KII in PC12 cells with Anti-ACTIVE® CaM KII pAb. PC12 cells were adhered to slides coated with collagen, fixed in 10% paraformaldehyde for 30 minutes, rinsed in PBS and permeabilized in methanol for 10 minutes at –20˚C. The cells were then blocked in 1% BSA in PBS for 45 minutes followed by 2% horse serum in PBS for 60 minutes. Cells were incubated overnight at 4˚C with (Panel A) Ab alone, (Panel B) Ab preincubated with a nonphosphorylated CaM KII peptide fragment (1μg/ml) or (Panel C) Ab preincubated with a phosphorylated CaM KII peptide fragment (1μg/ml). The Anti-ACTIVE® CaM KII pAb was used at 1:500 dilution and preincubated with peptide for 8 hours at 4˚C. After incubation with the Anti-ACTIVE® CaM KII pAb or Ab/peptide mixture, the cells were rinsed in PBS and incubated with a donkey anti-rabbit FITC-conjugated secondary Ab (1:500) for 60 minutes at room temperature.The results demonstrate that preincubation of the Anti-ACTIVE® CaM KII pAb with phosphorylated CaM KII peptide completely abolishes immunostaining (Panel C), but preincubation with nonphosphorylated CaM KII peptide has no effect on immunostaining (Panel A versus Panel B). Protocols developed and performed at Promega.
