Application Abreviews Notes
IHC-P 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/5000. Detects a band of approximately 63 kDa (predicted molecular weight: 63 kDa).


  • Function

    Mediates the association of the molecular chaperones HSC70 and HSP90 (HSPCA and HSPCB).
  • Sequence similarities

    Contains 2 STI1 domains.
    Contains 9 TPR repeats.
  • Domain

    The TPR 1 repeat interacts with the C-terminal of HSC70. The TPR 4, 5 and 6 repeats (also called TPR2A domain) and TPR 7, 8 and 9 repeats (also called TPR2B domain) interact with HSP90.

  • IHC image of STIP1/STI1 staining in a section of formalin-fixed paraffin-embedded human normal testis*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab202919, 1/200 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab202919 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
