Purpose | The ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utlizes monoclonal antibody specific for CCN3 / NOV / IGFBP9 coated on a 96-well plate. Standards and samples are addedto the wells, and any CCN3 / NOV / IGFBP9 present binds to the immobilized antibody. The wells are washed and ahorseradish peroxidase conjugated mouse anti-CCN3 / NOV / IGFBP9 monoclonal antibody is then added, producingan antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, whichproduces color in proportion to the amount of CCN3 / NOV / IGFBP9 present in the sample. To end the enzymereaction, the stop solution is added and absorbances of the microwell are read at 450 nm. |
Sensitivity | The minimum detectable dose of Human CCN3 / NOV / IGFBP9 was determined to be approximately 31.25 pg/mL. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard. |

Components |
Capture Antibody - 0.5 mg/mL of rabbit anti-NOV monoclonal antibody, Dilute to a workingconcentration of 2.0 μg/mL in CBS before coating. Detection Antibody - 0.5 mg/mL mouse anti-NOV monoclonal antibody conjugated tohorseradish-peroxidase (HRP) . Dilute to working concentration of 0.05 μg/mL in detection antibodydilution buffer before use. Standard - Each vial contains 100 ng of recombinant NOV. Reconstitute standard powder with1mL detection antibody dilution buffer. After reconstitution, store at -20 °C to -70 °C in a manualdefrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer,and a high standard of 2000 pg/mL is recommended. |

Alternative Name | NOV |
Background | Protein NOV homolog, also known as Nephroblastoma-overexpressed gene protein homolog, NOV, and CCN3, issecreted protein which belongs to the CCN family. CCN3 expression was observed in a broad variety of tissues fromthe early stage of development. It contains one CTCK (C-terminal cystine knot-like) domain, one IGFBP N-terminaldomain, one TSP type-1 domain, and one VWFC domain. CCN3, a founding member of the CCN family of growthregulators, was linked with hematology in 2003 when it was detected in human serum. CCN3 acts through the corestem cell signalling pathways including Notch and Bone Morphogenic Protein, connecting CCN3 with the modulation ofself-renewal and maturation of a number of cell lineages including hematopoietic, osteogenic and chondrogenic. AlteredCCN3 expression is associated with numerous solid tumors including glioblastoma, melanoma, adrenocortical tumours, prostate cancer and bone malignancies including osteosarcoma. CCN3 may affect the extracellular environment of theniche for hematopoietic stem cells. CCN3 has emerged as a key player in stem cell regulation, hematopoiesis and acrucial component within the bone marrow microenvironment. |
Application Notes | Optimal working dilution should be determined by the investigator. |

Calculation of Results |
Calculate the mean absorbance for each set of duplicate standards, controls and samples. Subtract the mean zero standard absorbance from each. Construct a standard curve by plotting the mean absorbance for each standard on the y-axis against the concentration on the x-axis and draw a best fit curve through the points on the graph. To determine the concentration of the unknowns, find the unknowns' mean absorbance value on the y-axis and draw a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the x-axis and read the concentration. If samples have been diluted, the concentration read from the standard curve must be multiplied by the dilution factor. Alternatively, computer-based curve-fitting statistical software may also be employed to calculate the concentration of the sample. |
