Assay Principle
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 human SMOC1 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)
1:1 Average % 96
Range % 92-100
1:2 Average % 103

The recovery of human SMOC1 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Target Background

(From Uniprot)
Plays essential roles in both eye and limb development. Probable regulator of osteoblast differentiation.
Gene References into Functions
  1. Missense mutation in exon 3 of SMOC1 segregated with the Waardenburg anophthalmia syndrome in the Iranian family. PMID: 28807869
  2. This is the first report of Waardenburg anophthalmia syndrome (WAS) caused by a SMOC1 variant in a Pakistani population. The mutation identified in the present investigation extends the body of evidence implicating the gene SMOC-1 in causing WAS. PMID: 28085523
  3. SMOC binds to Pro-EGF, but does not induce Erk phosphorylation via the EGFR. PMID: 27101391
  4. IL-17A but not IL-22 suppresses the replication of hepatitis B virus by inducing the expression of MxA and OAS. PMID: 23274784
  5. SMOC1 provides a link between prenatal hormone exposure and digit ratio. PMID: 23263445
  6. Homozygosity mapping and subsequent targeted mutation analysis of a locus on 14q24.2 identified homozygous mutations in SMOC1 (SPARC-related modular calcium binding 1) in eight unrelated families with Waardenburg Anophthalmia syndrome. PMID: 21750680
  7. The present study thus identified SPARC related modular calcium binding 1 as a new cancer-associated protein capable of interacting with tenascin-C in vitro PMID: 21349332
  8. these findings indicate that SMOC1/Smoc1 is essential for ocular and limb development in both humans and mice. PMID: 21194678
  9. Waardenburg anophthalmia syndrome is genetically heterogeneous; a second was locus found on chromosome 14, and mutations in SMOC1 were shown also cause this syndrome. PMID: 21194680
  10. Analyzed the secretory protein profiles of BMSCs grown in osteogenic medium (OSM) and identified SPARC-related modular calcium-binding protein 1 (SMOC1), a member of the SPARC family, as a regulator of osteoblast differentiation of BMSCs. PMID: 20359165
  11. isolation of the novel gene SMOC-1 encoding a secreted modular protein containing an EF-hand calcium-binding domain; localization within basement membranes in kidney and skeletal muscle and expression in the zona pellucida surrounding the oocyte PMID: 12130637
  12. SMOC-1 is of physiological interest because it codes a secreted glycoprotein with five domains, each containing regions homologous to those on other proteins that mediate cell-matrix interactions. PMID: 17386346
