R-spondins (RSPOs), such as RSPO2, are secreted proteins that regulate beta-catenin (CTNNB1) signaling. Xenopus and human RSPO2 enhanced mouse Wnt3a signaling in transfected human embryonic kidney cells. C-terminally truncated Xenopus Rspo2, but not the full-length protein, was secreted from cells and retained its activity. Mutation analysis showed that the TSP1 domain of Xenopus Rspo2 was dispensable for activity, but the furin domains were required. RT-PCR analysis showed that Xenopus embryos injected with Wnt8 or beta-catenin induced Rspo2 and Rspo3. Overexpression of Rspo2 in Xenopus activated the Wnt/beta-catenin pathway upstream of dishevelled (DVL1), interfered with Tgfb-type growth factors, and promoted myogenesis.

Human R-spondin-2 (RSPO2) ELISA Kit employs a two-site sandwich ELISA to quantitate RSPO2 in samples. An antibody specific for RSPO2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRSPO2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for RSPO2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RSPO2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
