Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of mouse CST7 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Data

Function Inhibits papain and cathepsin L but with affinities lower than other cystatins. May play a role in immune regulation through inhibition of a unique target in the hematopoietic system.
Gene References into Functions
  1. High CST7 expression is associated with Alzheimer's disease. PMID: 28904096
  2. Our results validate cystatin F as a useful biomarker of early pathogenesis in experimental models of prion disease, and point to unexpected species-specific differences in the transcriptional responses to prion infections. PMID: 28178353
  3. During the active remyelinating phase, both CysF knockdown (CysFKD) and microglial-selective CatC overexpression (CatCOE) showed a worsening of the demyelination in Plp(4e/-) transgenic mice. Conversely, during the chronic demyelinating phase, CatC knockdown (CatCKD) ameliorated the demyelination. Our results suggest that the balance between CatC and CysF expression controls the demyelination and remyelination process. PMID: 28251676
  4. The cystatin F expression in the activated microglia is closely associated with the effect of the A2A receptors, which may be related to the neuroinflammatory responses occurring during the pathological process. PMID: 23285090
  5. an inhibitory activity other than cystatin F quenches CatL activity in activated macrophages PMID: 21956111
  6. Expression of cystatin F indicates ongoing demyelination and remyelination; absence of cystatin F expression indicates cessation of remyelination in the demyelinating area. PMID: 21344476
