Tested Applications

• Positive WB detected in: human skeletal muscle tissue, A549 cells
• Positive IHC detected in: human lung cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF/ICC detected in: A549 cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:4000
• Immunohistochemistry (IHC): IHC : 1:50-1:500
• Immunofluorescence (IF)/ICC: IF/ICC : 1:200-1:800

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

RSPO3, also named as R-spondin-3, is a 272 amino acid protein, which contains 1 TSP type-1 domain and 2 FU (furin-like) repeats. RSPO3 may be a secreted protein and belongs to the R-spondin family. RSPO3 is expressed at higher level in placenta, small intestine, fetal thymus and lymph node. RSPO3 is an activator of the canonical Wnt signaling pathway by acting as a ligand for LGR4-6 receptors. The four R-spondins (RSPO1-4) and three related leucinerich repeat-containing G-protein coupled receptors, LGR4, LGR5, and LGR6 (LGR4-6), constitute a ligand-receptor system that plays critical roles in development, stem cell survival, and oncogenesis. Ectopic expression of RSPO2/3in mouse mammary epithelial cells led to an increase in invasiveness in vitro and in tumor formation and metastasis in vivo.
