  • Function

    Appears to regulate cell growth through interactions with the extracellular matrix and cytokines. Binds calcium and copper, several types of collagen, albumin, thrombospondin, PDGF and cell membranes. There are two calcium binding sites; an acidic domain that binds 5 to 8 Ca(2+) with a low affinity and an EF-hand loop that binds a Ca(2+) ion with a high affinity.
  • Sequence similarities

    Belongs to the SPARC family.
    Contains 1 EF-hand domain.
    Contains 1 follistatin-like domain.
    Contains 1 Kazal-like domain.
  • Developmental stage

    Expressed at high levels in tissues undergoing morphogenesis, remodeling and wound repair.
  • Cellular localization

    Secreted > extracellular space > extracellular matrix > basement membrane. In or around the basement membrane.

  • ab14174 (1/1000) staining SPARC in human substanta nigra using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of the cytoplasm and extracellular matrix.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH 6.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
  • Immunohistochemical analysis of E14 and E16 mouse choroid plexus tissue, staining SPARC with ab14174. Sections were blocked with blocking agents and incubated with primary antibody (1/10000) overnight at 4°C. Staining was detected using DAB.
