    PRKACA and PRKACB are members of the Ser/Thr protein kinase family and are a catalytic subunit of cAMP-dependent protein kinase. cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the cAMP-dependent protein kinase, which transduces the signal through phosphorylation of different target proteins. The inactive kinase holoenzyme is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits.

  • 細胞内局在

    Cytoplasm. Nucleus. Note=Translocates into the nucleus (monomeric catalytic subunit). The inactive holoenzyme is found in the cytoplasm

    Peptide Competition and Phosphatase Treatment: Lysates prepared from Y1 Adrenocortical cells were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were either left untreated (1-4) or treated with lambda  phosphatase (5), blocked with a 5% BSA-TBST buffer for two hours at room temperature, then incubated with 0.35 µg/mL ab5815 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1, 5), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphothreonine containing peptide (3), or, the phosphopeptide immunogen (4). After washing, membranes were incubated with goat F(ab’ 2 anti-rabbit IgG HRP conjugate  and bands were detected using the Pierce SuperSignalTM method. The data show that the peptide corresponding to PKA [pT197] blocks the antibody signal, thereby demonstrating the specificity of the antibody. The data also show that phosphatase stripping eliminates the signal, verifying that the antibody is phospho-specific.

BATCH NUMBER 111494 ORDER NUMBER Forgot DESCRIPTION OF THE PROBLEM No signal or weak signal: No signal at all in cultured cell immunostaining; No signal at all in Western blot against whole cell lysis SAMPLE SH-SY5Y cells and HEK293 cell cultured on 2-well slides, treated/untreated with Ethanol; HEK293 cell lysis treated/untreated with Ethanol, runned on 12%SDS gel and transfered to PVDF membrane. PRIMARY ANTIBODY Abcam Ab5815/Rabbit/2.5% BSA in TBS/1:200 or 1:500 or 1:1000/4oC overnight/0.1% TBST 15 minutes DETECTION METHOD ECL POSITIVE AND NEGATIVE CONTROLS USED PKA transfected/non-transfected HEK293 cells work as positive or negative control, and each has 100mM Ethanol treated and untreated samples. According to references, ethanol treatment increases PKA phosphralation. And even if ethanol doesn't increase PKA phosphralation in this case, there still should be phosphrelated PKA in normal condition HEK293 cell lysis. In other words, there should always be specific phosphrelated PKA bands in the cell lysis, but unfortunately it never appears,not even any non-specific bands, after lots of repeats and various dilutions. ANTIBODY STORAGE CONDITIONS -20oC SAMPLE PREPARATION Western: M-PER lysis buffer(PIERCE)/Protease Inhibitor Tablet(Roche)/1XLDS loading buffer(Invitrogen), 100oC 5minutes for denature For western, 1:200~1000 dilution of Ab5815 in 2.5%BSA incubate overnight, other procedures are standard Immunostaining:4%PFA fixed cells grown on 2-well slides(Clontech) 15 minutes,0.1% TritonX-100 penetrance 15minutes,5%BSA blocked 1 hour, 1:100 or 1:250 dilution of Ab5815 in 2.5% BSA overnight incubation. Other procedure are standard. AMOUNT OF PROTEIN LOADED 20~30 ug/lane ELECTROPHORESIS/GEL CONDITIONS 12% SDS reducing gel, 100V 2 hours TRANSFER AND BLOCKING CONDITIONS Standard transfer buffer (Invitrogen) and blocking buffer (5% fat-free milk in TBS) SECONDARY ANTIBODY Santa Cruz Inc/Goat against Rabbit HRP-conjugated 2nd Antibody/2.5% fat-free milk/1:5000/RT 1 hour/3 times wash, 0.1% TBST 15 minutes HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 6 HAVE YOU RUN A "NO PRIMARY" CONTROL? Yes DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? Dilution, 1:200; 1:500; 1:1000. ADDITIONAL NOTES I believe this batch of antibody Ab5815 is a bad product, the antibody died when it arrived. When it arrived last year, I first tried it in immunostaining with 1:100/1:250 dilution but never get any signal, I thought it may not suitable for immunostaing. Then in April when I use it for western blots, it never gave any, literally, any bands on the blots. I changed the dilution from 1:1000 to 1:500 to 1:200 but never got anything. This made me believe this batch of Ab5815 was dead when it was first packaged. Because it arrived in blue ice pretty fast after ordering and had been kept in -20oC ever since, so I think it's Abcam's package problem or this batch wasn't good. I have used a lot of Abcam antibodies and all others worked fine except this one was so frustrating, I reqest a free replacement for this antibody as soon as possible. Best Yiguo

Answer

Thank you for your enquiry. I am sorry to hear that you have been having difficulties with this antibody. I have read your technical questionaire and you have tried many of the suggestions that I would recommend. You have tried various dilutions and induced PKA alpha phosphorylation. Quality is important to Abcam and therefore I would like to offer you a credit note against your original purchase provided that the antibody was purchased within the past 90 days. If this is the case please email me details of the order including the order number and date of purchase. I look forward to hearing from you.

Question

I have a technical question about the protein kinase A antibody. I would like to do a Western Blot on PKA catalytic subunit (Sigma Cat no: P8289). I was using the Anti-PKA from MBL (Cat no: JM-3115-100), however I could not get any band even with the pure enzyme. (Note that they use the synthetic peptide (residues 7-21) based on 40kDA alpha-form of the catalytic subunit as the immunogen). The question is do you have any antiPKA which is specific for PKA catalytic subunit only (for both the alpha and beta forms), NOT regulatory units, for Western blot analysis. If so what is the catalogue number, the price and the availability ?

Question

I have a customer who is using two of your PKA antibodies in immunofluorescence. He is testing frozen cartiledge tissue sections, already mounted on slides (no paraffin). He wishes to know which fixative base would be best to use: acetone or formaldehyde.

Answer

I'm afraid I don't know. ab8356 was shown to work in IF by one of our customers, Dr Martha Simpson-Holley . Your customer may contact her via the e-mail link in the reviews section of Abcam's online datasheet to request more details of her protocol. To our knowledge, ab5815 has only been tested in WB, so I am unable to advise how tissue samples should be prepared when it's used in IHC.
