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 rat SEPP1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)
1:1000 Average % 92

Target Data

Function Might be responsible for some of the extracellular antioxidant defense properties of selenium or might be involved in the transport of selenium. May supply selenium to tissues such as brain and testis.
Gene References into Functions
  1. A chromatin immunoprecipitation (ChIP) assay revealed that EPA decreases binding of SREBP-1c to the SELENOP promoter. Knockdown of Srebf1 resulted in a significant down-regulation of Selenop expression. PMID: 28465347
  2. Data indicate that Selenoprotein P SEPP1 processivity is intrinsic, but efficiency is governed by selenium levels. PMID: 25063811
  3. metformin decreases binding of FoxO3a, a direct target of AMPK, to the SEPP1 promoter. PMID: 24257750
  4. Sepp1 secreted from epithelial cells may support the intestinal immune system by providing immune cells (including plasma cells) with selenium PMID: 24157689
  5. apoER2-mediated uptake of long isoform Sepp1 is responsible for selenium distribution to tissues throughout the body. PMID: 22761431
  6. investigation of Sepp1 expression in adipocytes during adipogenesis and oxidative stress in models of obesity and insulin resistance PMID: 20959537
  7. tear SeP is a key molecule to protect the ocular surface cells against environmental oxidative stress PMID: 20360971
  8. mass spectrometric characterization of full-length protein and three isoforms shortened at the C terminus PMID: 11821412
  9. selenenylsulfide linkages Sec304-Cys314 and Cys306-Sec316 were present; selenoprotein P contains these two selenenylsulfide bonds PMID: 15712351
  10. Sertoli cell ApoER2 is a Sepp1 receptor and a component of the selenium delivery pathway to spermatogenic cells PMID: 17314095
  11. In conclusion, the selenoprotein P promoter is a target of the Akt/FoxO signal transduction cascade and SeP expression is regulated at the level of transcription by the forkhead box protein FoxO1a in human and rat hepatoma cells. PMID: 17986386
