Secreted frizzled-related protein 4 is a protein that is encoded by the SFRP4 gene.Secreted frizzled-related protein 4 (SFRP4) is a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled Proteins. SFRPs act as soluble modulators of Wnt signaling. The expression of SFRP4 in ventricular myocardium correlates with apoptosis related gene expression.
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

The recovery of Human sFRP-4 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
Sample Type | Range(%) | Average Recovery(%) |
Serum(n=8) | 84-101 | 96 |
Plasma(n=8) | 92-105 | 102 |
Samples were spiked with high concentrations of Human sFRP-4 and diluted with Universal Diluent to produce samples with values within the range of the assay.
