Our Abpromise guarantee covers the use of ab109508 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/10000 - 1/50000. Detects a band of approximately 13 kDa (predicted molecular weight: 15 kDa).|
|IHC-P||1/250 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
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
Macular degeneration, age-related, 11
Sequence similaritiesBelongs to the cystatin family.
modificationsThe 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.

Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: CST3 knockout HAP1 whole cell lysate (20 µg)
Lane 3: Caco2 whole cell lysate (20 µg)
Lane 4: U20S whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab109508 observed at 15 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab109508 was shown to specifically react with CST3 when CST3 knockout samples were used. Wild-type and CST3 knockout samples were subjected to SDS-PAGE. Ab109508 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 10000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
