Background Information

Fis1 (fission 1) is an integral mitochondrial outer membrane protein that participates in mitochondrial fission by interacting with dynamin-related protein 1 (Drp1). Excessive mitochondrial fission is associated with the pathology of a number of neurodegenerative or neurodevelopmental diseases. Increased expression of Fis1 has been found in Huntington's disease (HD)-affected brain, Alzheimer's disease (AD) patients, and autism spectrum disorder. This antibody was raised against the full-length of human Fis1 protein, and recognizes endogenous Fis1 protein in various lysates. (PMID: 21257639, 21459773, 23333625)

RPE cell over-expressing pcDNA hFis1. Note 1:500 was used here to detect over-expressed Fis1, but we also use 1:100 when detecting endogenous Fis1. Also successfully used to detect endogenous Fis1 levels via Western Blot (used @ 1:1000).

  • Applications: Western Blot,Immunofluorescence
  • Primary Antibody Dilution: 1:100 - 1:500
