RSPO2 Antibody / R-spondin-2

Overview

RSPO2 Antibody / R-spondin-2 is an antibody targeting RSPO2, raised in Rabbit for protein detection and localization studies where these specifications are required.

Key elements and design rationale

• Target: RSPO2.
• Antibody identity: Polyclonal (rabbit origin); Rabbit Ig.
• Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
• Format: Antigen affinity purified.
• Species reactivity: Human.
• Listed applications: WB, IHC-P, FACS (refer to on-page specifications for application-specific guidance).

Biological background

RSPO2 is a member of the R-spondin family of proteins, which are known for their ability to regulate the Wnt signaling pathway. This pathway plays a crucial role in cell proliferation, differentiation, and stem cell maintenance. RSPO2 specifically has been shown to enhance Wnt signaling, leading to increased cell growth and tissue regeneration. Research on RSPO2 is still in its early stages, but some studies have already shown promising results. For example, a study published in the journal Cell Stem Cell found that RSPO2 can enhance the regenerative capacity of intestinal stem cells, potentially leading to new treatments for diseases like inflammatory bowel disease.

Research relevance and current trends

• Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
• Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
• Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.

Common research applications

• Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
• Immunohistochemistry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
• Flow cytometry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.

Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.

Notes for experimental interpretation

• Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
• Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
• Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
• Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.
