Our Abpromise guarantee covers the use of ab2516 in the following tested applications.

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

Application Notes
WB Use a concentration of 0.01 - 0.03 µg/ml. Detects a band of approximately 18 kDa (predicted molecular weight: 16 kDa).Can be blocked with Human Cystatin C peptide (ab22916).


  • FunctionAs an inhibitor of cysteine proteinases, this protein is thought to serve an important physiological role as a local regulator of this enzyme activity.
  • Tissue specificityExpressed 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 diseaseAmyloidosis 6
    Age-related macular degeneration 11
  • Sequence similaritiesBelongs 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.
