Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human SFRP1 recombinant protein (A204-K314).
- Molecular weight context: reported MW: 35 kDa; calculated MW: 30570 MW
- Reactivity: Human,Mouse,Rat
- Applications: ELISA, Flow Cytometry, IF, IHC, ICC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
secreted frizzled related protein 1. Secreted frizzled-related protein 1, also known as SFRP1, is a protein which in humans is encoded by the SFRP1 gene. It is mapped to 8p11.21. 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. Functional note: Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through 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. Reported localization: Secreted. Expression/tissue context: 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.
Research relevance and current trends
- Axonal Guidance Proteins: Researchers commonly examine how SFRP1 relates to this theme using model systems and orthogonal readouts.
- Developmental Biology: Researchers commonly examine how SFRP1 relates to this theme using model systems and orthogonal readouts.
- Growth and Development: Researchers commonly examine how SFRP1 relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative SFRP1 levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of SFRP1 across tissue regions and cell types using matched controls.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
