No significant cross-reactivity or interference between Human SFRP1 and analogues was observed.

Store all reagents at 2-8 degree C

Samples: Serum, Plasma, Tissue Homogenate, Feces and Urine. Assay Type: Sandwich. Detection Range: 31.2 pg/ml - 1000 pg/ml. Sensitivity: 5.0 pg/ml.

Intended Uses: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic or diagnostic applications! It is intended to be determinated SFRP1 concentrations in Human serum, plasma and other body fluids. Using Purified Human SFRP1 antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add SFRP1 and SFRP1 antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color under HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of SFRP1 in the samples is then determined by comparing the O.D. of the samples to the standard curve. Intra-assay Precision: Intra-assay CV (%) is less than 15%. Inter-assay Precision: Inter-assay CV (%) is less than 15%. [CV(%) = SD/mean ×100]

This gene encodes a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. Members of this family act as soluble modulators of Wnt signaling; epigenetic silencing of SFRP genes leads to deregulated activation of the Wnt-pathway which is associated with cancer. This gene may also be involved in determining the polarity of photoreceptor cells in the retina. [provided by RefSeq, Sep 2009]

SFRP1: Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through direct interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP1 decreases intracellular beta-catenin levels. Has antiproliferative effects on vascular cells, in vitro and in vivo, and can induce, in vivo, an angiogenic response. In vascular cell cycle, delays the G1 phase and entry into the S phase. In kidney development, inhibits tubule formation and bud growth in metanephroi. Inhibits WNT1/WNT4-mediated TCF-dependent transcription. Interacts with WNT1, WNT2 and FRZD6. Interacts with WNT4 and WNT8. Down-regulated in colorectal and breast tumors. Up- regulated in uterine leiomyomas under high estrogenic conditions. Expression, in leiomyomal cells, also increased both under hypoxic and serum deprivation conditions. Widely expressed. Absent from lung, liver and peripheral blood leukocytes. Highest levels in heart and fetal kidney. Also expressed in testis, ovary, fetal brain and lung, leiomyomal cells, myometrial cells and vascular smooth muscle cells. Expressed in foreskin fibroblasts and in keratinocytes. Belongs to the secreted frizzled-related protein (sFRP) family. Protein type: Secreted; Secreted, signal peptide.
