WISP-1 belongs to the CCN (CTGF/CYR61/NOV) family of secreted proteins that share a common multimodular organization. Each family member has an IGFBP domain, a von Willebrand type C domain, a thrombospondin 1 domain and a C-terminal cysteine knot domain. Depending on cell context, WISP-1 can either promote or inhibit tumorigenesis.

Product Summary for Mouse/Rat WISP-1/CCN4 Quantikine ELISA Kit
The Quantikine Mouse/Rat WISP-1/CCN4 immunoassay is a 4.5 hour solid-phase ELISA designed to measure WISP-1 in mouse or rat cell culture supernates, tissue lysates, serum, plasma, and urine. It contains NS0-expressed recombinant mouse WISP-1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate
the recombinant mouse WISP-1. Results obtained using natural mouse or rat WISP-1 showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural WISP-1.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of a known concentration were tested in separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of kit components.

Protocols
View specific protocols for Mouse/Rat WISP-1/CCN4 Quantikine ELISA Kit (MWSP10):
Refer to the product for complete assay procedure.
Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 50 µL of Assay Diluent to each well.
- Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
- Aspirate and wash 4 times.
- Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
- Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
