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

Application Abreviews Notes
WB 1/25000 - 1/50000. Detects a band of approximately 90 kDa (predicted molecular weight: 86 kDa).
IP 1/50.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • Target

    • Function
      Calcium-regulated, actin-modulating protein that binds to the plus (or barbed) ends of actin monomers or filaments, preventing monomer exchange (end-blocking or capping). It can promote the assembly of monomers into filaments (nucleation) as well as sever filaments already formed. Plays a role in ciliogenesis.
    • Tissue specificity
      Phagocytic cells, platelets, fibroblasts, nonmuscle cells, smooth and skeletal muscle cells.
    • Involvement in disease
      Defects in GSN are the cause of amyloidosis type 5 (AMYL5) [MIM:105120]; also known as familial amyloidosis Finnish type. AMYL5 is a hereditary generalized amyloidosis due to gelsolin amyloid deposition. It is typically characterized by cranial neuropathy and lattice corneal dystrophy. Most patients have modest involvement of internal organs, but severe systemic disease can develop in some individuals causing peripheral polyneuropathy, amyloid cardiomyopathy, and nephrotic syndrome leading to renal failure.
    • Sequence similarities
      Belongs to the villin/gelsolin family.
      Contains 6 gelsolin-like repeats.
    • Post-translational
      Phosphorylation on Tyr-86, Tyr-409, Tyr-465, Tyr-603 and Tyr-651 in vitro is induced in presence of phospholipids.
    • Cellular localization
      Cytoplasm > cytoskeleton and Secreted.
