Our Abpromise guarantee covers the use of ab217569 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
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use at an assay dependent concentration. Detects a band of approximately 13 kDa (predicted molecular weight: 15 kDa).
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function

      As an inhibitor of cysteine proteinases, this protein is thought to serve an important physiological role as a local regulator of this enzyme activity.
    • Tissue specificity

      Expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level). Expressed in various body fluids, such as the cerebrospinal fluid and plasma. Expressed in highest levels in the epididymis, vas deferens, brain, thymus, and ovary and the lowest in the submandibular gland.
    • Involvement in disease

      Amyloidosis 6
      Macular degeneration, age-related, 11
    • Sequence similarities

      Belongs to the cystatin family.
    • Post-translational

      The Thr-25 variant is O-glycosylated with a core 1 or possibly core 8 glycan. The signal peptide of the O-glycosylated Thr-25 variant is cleaved between Ala-20 and Val-21.
