Overview

  • Product name

    Anti-Caspase-4 antibody
    See all Caspase-4 primary antibodies

  • Description

    Rabbit polyclonal to Caspase-4

  • Host species

    Rabbit

  • Specificity

    ab22687 recognises proenzyme (43 kDa) and the large subunit (19 kDa) and small (10 kDa) subunits of mature enzyme. For the mature enzyme, reactivity is strongest with the large subunit. No cross reactivity with other human caspases tested (1 to 3, 5 to 10, 14).

    Reacts with: Human

  • Immunogen

    Recombinant full length protein corresponding to Human Caspase-4.

Properties

Applications

Our Abpromise guarantee covers the use of ab22687 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB
  • Application notes
    WB: 1/8000 - 1/16000. Detects bands of approximately 43, 19 and 10 kDa corresponding to the proenzyme, the large subunit and small subunits of mature enzyme, respectively (using Alkaline phosphatase-linked secondary antibody).

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.

    • Target

    • Function

      Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves caspase-1.

    • Tissue specificity

      Widely expressed, with highest levels in spleen and lung. Moderate expression in heart and liver, low expression in skeletal muscle, kidney and testis. Not found in the brain.

    • Sequence similarities

      Belongs to the peptidase C14A family.
      Contains 1 CARD domain.

    • Post-translational
      modifications

      The two subunits are derived from the precursor sequence by an autocatalytic mechanism or by cleavage by Caspase-8.

      Answer

      Thank you for contacting us and sorry for the delay in getting back to you.

      I can now share with you that as discussed over the phone,this antibody is supplied as whole rabbit serum and theconcentration has therefore not been determined.However, I can confirm that therecommended dilution for this antibody forWestern blottingis1:2000-1:4000. This has been amended fromthe original recommendation of 1/8000-1/16000.

      I hope this information has been of help. If you require any further information please do not hesitate to contact us again.

      Question

      Last time you kindly advise our customer these suggestion below, our customer had change their condition as you recommended. 2) Load less sample protein i.e. ~20 ug/lane. 5) The recommended dilution in WB is 1/8000 - 1/16000 using Alkaline phosphatase-linked secondary antibody. Since you used an HRP-conjugated secondary in ECL+, which is generally more sensitive than the AP detection, I suggest diluting ab22687 at ~1:20000-300000 and incubating at room temp for 1 hr or 4C overnight. protein loading 20 ug blocking:4?, overnight 2nd Ab: dilute 1/200, 000(jackson innunoresearch) We would be appreciated if you could provide them the credit note or a replacement vial. If there is any information you need, please do not hesitate to contact with me. Thanks for your help again.
