  • Handling

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Toxic, refer to SDS for further information.

  • Immunofluorescent analysis of 4 % paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (human epithelial cell line from cervix adenocarcinoma)(+/- treatment with 10μM carbonyl cyanide 3-chlorophenylhydrazone (CCCP, ab141229) for 24 hours) cells labeling PINK1 with ab216144 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on HeLa cells treated with 10μM carbonyl cyanide 3-chlorophenylhydrazone (CCCP, ab141229) for 24 hours. The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).

    The negative controls are as follows:
    -ve control: PBS, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

  • All lanes : Anti-PINK1 antibody [EPR20730] (ab216144) at 1/1000 dilution

    Lane 1 : HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate
    Lane 2 : HeLa cells (treated with 10uM carbonyl cyanide 3-chlorophenylhydrazone (CCCP, ab141229) for 24 hours) whole cell lysate

    Lysates/proteins at 20 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

    Developed using the ECL technique.

    Observed band size: 62 kDa
    why is the actual band size different from the predicted?

    Exposure time: 5 seconds

    Blocking and dilution buffer: 5% NFDM/TBST

    PINK1 can be induced by CCCP treatment (PMID: 24184327).

  • PINK1 was immunoprecipitated from 0.35 mg of HeLa (human epithelial cell line from cervix adenocarcinoma) (treated with 10uM carbonyl cyanide 3-chlorophenylhydrazone (CCCP. ab141229) for 24 hours) whole cell lysate with ab216144 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab216144 at 1/500 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution.

    Lane 1: HeLa (CCCP-treated, ab141229) lysate 10 μg (Input). 
    Lane 2: ab216144 IP in HeLa (CCCP-treated, ab141229) lysate. 
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab216144 in HeLa (CCCP-treated, ab141229) whole cell lysate.

    Blocking and dilution buffer: 5% NFDM/TBST.

  • MCF7 cells were incubated at 37°C for 2 hours with vehicle control (0 μM) and different concentrations of CCCP (ab 141229). Increased expression of AKT1 (phospho S473) (ab81283) in MCF7 cells correlates with an increase in CCCP concentration, as described in literature.

    Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10 μg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab81283 at 2 μg/ml and ab8227 at 1 μg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 and visualised using ECL development solution.
