Background

DP-1 antiserum shows distinct punctate membrane staining of epithelia. In Western blot analysis the antiserum reacts specifically with the desmoplakin DPI and DPII polypeptides.
Reactivity on cultured cell lines: Several human carcinoma cell lines, such as MCF-7, A-431, HaCaT and CaCo2.

FAQs
  • PVDF membranes show better results than nitrocellulose (higher capacity, allows for more stringent washing conditions in case of background problems).
  • Use freshly prepared blocking solution (e.g. 5% nonfat dry milk, 0.05% Tween 20), block for at least 1 h at room temperature.
  • Use the antibody in a higher dilution, but prolong incubation time and exposure time.
  • Always use a fresh aliquot of the antibody.
  • Do not repeatedly freeze the antibody (eventually centrifuge shortly after thawing to remove cryo-precipitates).
  • Include an additional washing step.
    You might also try more stringent wash conditions, e.g. add 0.5 M NaCl to the wash buffer.
  • Always use a fresh aliquot of secondary antibody.
  • In case you use ECL most the guinea pig antibody should be diluted further in order to get rid of the background.

Most of our purified mouse antibodies contain 0.5% BSA as stabilizer. If BSA was added to the antibody solution, it is stated in the datasheet.
The supernatant format contains FCS proteins from cell culture medium supplemented with FCS.
The serum antibodies contain other proteins present in serum.

Lyophilized antibodies can be stored at 2-8°C until expiration.
Most of our liquid antibodies and reconstituted lyophilized antibodies may be stored for short term storage (up to 3 month) at 2-8°C. For long term storage we recommend to store the antibody at -20°C in aliquots. Please avoid freeze and thaw cycles.
Most of our conjugated antibodies should be stored at 2-8°C.
The individual storage conditions are mentioned on the datasheet.

The expiration date of our antibodies is indicated on the product label.
  1. Methanol/ acetone fixation: Immerse slide in precooled (-20°C) methanol for 5 min, immerse in precooled (-20°C) acetone for 30-60 sec, let specimen air dry before antibody incubation.
  2. Methanol/ acetone fixation plus detergent permeabilization: After methanol/ acetone fixation and air-drying dip slide either in a solution containing 0.1-0.2% Triton X-100 in PBS or in 0.1% saponin in PBS for 1-5 min at room temperature (enhances accessibility of many cytoskeletal antigens).

  • Air-drying of the section.
  • Block with the serum of the species in which the secondary antibody was raised for 30 min.
  • Incubation with 1st antibody 1 h at RT in moist chamber.
  • Wash 3x with PBS.
  • Incubation with appropriate fluorescent secondary antibody, 30-60 min at RT.
  • Wash 3x with PBS.
  • Immerse shortly into ethanol.
  • Let air dry.
  • Cover with mounting medium.

Most of our antibodies contain 0.09% sodium azide as preservative. If a preservative is added, it is mentioned in the datasheet.
The optimal antibody dilution for your specific protocol and application needs to be titrated in your lab with your equipment and sample. The optimal dilution may vary between protocols and samples. A good dilution for starting the titration is the dilution mentioned in the datasheet. If the sample needs a specific treatment (eg. Antigen retrieval for IHC on FFPE sections) this should also be mentioned on the antibody datasheet. 
PROGEN antibodies are shipped at ambient temperature. The antibodies are stable at ambient temperature for the shipment period. Please store the antibodies as indicated in the datasheet upon arrival.
  • Wash cells 1x with PBS (37°C).
  • Fix in ice-cold (pre-cooled to -20°C) methanol (5-10 min), followed by ice-cold acetone (30-60 sec).
  • Optional: to enhance the epitope accessibility incubate for 5 min with 0.1% Triton-X100 in PBS.
  • Let air dry.
  • Block with the serum of the species in which the secondary antibody was raised for 30 min at RT.
  • Incubate with primary antibody overnight at 4°C.
  • Wash 3x with PBS at RT.
  • Incubate 1 h with fluorochrome-conjugated secondary antibody.
  • Wash 2x with PBS.
  • Embed in mounting medium.

  • Homogenization of tissue in PBS (supplemented with protease inhibitors).
  • Centrifugation at 10E4 x g.
  • Optional: treat pellet with DNase.
  • Resuspend pellet in detergent buffer (e.g. 1% Triton X-100), stir for 1 h at 2-8°C.
  • Centrifugation at 10E4 x g.
  • Resuspend pellet in high salt buffer (with 1.5 M KCl), stir for 1 h at 2-8°C.
  • Centrifugation at 10E4 x g.
  • Resuspend pellet in low salt buffer (e.g. 50 mM NaCl), stir for 30 min at 2-8°C.
  • Centrifugation at 10E4 x g: pellet contains raw cytoskeletal fraction.

The concentration of specific antibody in our guinea pig serum is not determined.
In guinea pigs the antibody concentration in serum varies from 10 to 20 mg/ml; specific antibodies represent normally about 0.1-1% of total IgG. Total protein concentration varies from 40 to 65 mg/ml, with the main constituent (about 60%) being albumin.
  • Transfer from a low concentration acrylamide gel (e.g. 8%).
  • Reduce the methanol concentration of the transfer buffer (limit is 50% of the routine concentration 20% methanol).
  • Use the wet transfer method and transfer at least 4 h (or better overnight) at 100-200 mA.
  • In order to prevent the accumulation of gas bubbles, stir the transfer buffer continuously during the transfer (e.g. with a magnetic stirrer).
  • If possible use a cytoskeletal preparation of your material to be analyzed (in the case of cultured cells additionally DNase treatment) rather than whole cell lysate.
  • As a general rule we would like to recommend loading that much protein into one gel lane that the intermediate filament polypeptides (in the 40-60 kD range) can be readily detected in a control gel stained with Coomassie blue.
