Precision
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.
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of rat S100A1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
Small calcium binding protein that plays important roles in several biological processes such as Ca(2+) homeostasis, chondrocyte biology and cardiomyocyte regulation. In response to an increase in intracellular Ca(2+) levels, binds calcium which triggers conformational changes. These changes allow interactions with specific target proteins and modulate their activity. Regulates a network in cardiomyocytes controlling sarcoplasmic reticulum Ca(2+) cycling and mitochondrial function through interaction with the ryanodine receptors RYR1 and RYR2, sarcoplasmic reticulum Ca(2+)-ATPase/ATP2A2 and mitochondrial F1-ATPase. Facilitates diastolic Ca(2+) dissociation and myofilament mechanics in order to improve relaxation during diastole.
Gene References into Functions
  1. depletion of S100A1 was observed in ischemic cardiomyocytes, and S100A1 plasma concentration was also significantly higher than that of the sham-operated group PMID: 23683996
  2. S100A1 is involved in the maintenance of the genetic program that defines normal myocardial function and its downregulation is permissive for the induction of genes that underlie myocardial hypertrophy PMID: 12619862
  3. S100A1 and calmodulin compete for the same binding site on ryanodine receptor PMID: 18650434
  4. in sympathetic neurons exogenous S100A1 may lead to an increase of sympathetic output. PMID: 19657060
Subcellular Location
Cytoplasm. Sarcoplasmic reticulum. Mitochondrion.
Protein Families
S-100 family
Tissue Specificity
Although predominant among the water-soluble brain proteins, S100 is also found in a variety of other tissues.
