Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E.coli-derived human SFRP2 recombinant protein (Position: L104-C295). Human SFRP2?shares?99%?amino?acid?(aa)?sequence?identity?with mouse SFRP2. (reported region: L104-C295).
- Molecular weight context: reported MW: 33 kDa; calculated MW: 33490 MW
- Reactivity: Human
- Applications: ELISA, 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 2; Secreted frizzled-related protein 2. SFRP2 is also known as FRP-2, SARP1 or SDF-5. It is Expressed in adipose tissue, heart, brain, skeletal muscle, pancreas, thymus, prostate, testis, ovary, small intestine and colon. Highest levels in adipose tissue, small intestine and colon. 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. SFRPs act as soluble modulators of Wnt signaling. Methylation of this gene is a potential marker for the presence of colorectal cancer.? 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. SFRP2 may be important for eye retinal development and for myogenesis. Reported localization: Secreted . Expression/tissue context: Expressed in adipose tissue, heart, brain, skeletal muscle, pancreas, thymus, prostate, testis, ovary, small intestine and colon. Highest levels in adipose tissue, small intestine and colon. .

Common research applications
- Western blotting: compare relative SFRP2 (Secreted frizzled-related protein 2) levels across conditions; band patterns may reflect isoforms and processing.
- 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.
- Family / similarity context: Belongs to the secreted frizzled-related protein (sFRP) family.
- 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.
