Product Description
Human R-spondin-2 (RSPO2) ELISA Kit | KTE60782 | Abbkine
Application: This 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.

Usage Note: • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage Instruction: The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping: Gel pack with blue ice.

Background: 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.
