Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 78 kDa (predicted molecular weight: 72 kDa).Can be blocked with GRP78 BiP peptide (ab176143).
IHC-P 1/250 - 1/500. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. (Heat to 98°C, allow to cool for 10-20 minutes)
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function
      Probably plays a role in facilitating the assembly of multimeric protein complexes inside the endoplasmic reticulum. Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10, probably to facilitate the release of DNAJC10 from its substrate.
    • Involvement in disease
      Autoantigen in rheumatoid arthritis.
    • Sequence similarities
      Belongs to the heat shock protein 70 family.
    • Cellular localization
      Endoplasmic reticulum lumen. Melanosome. Cytoplasm. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
