Product Summary for Mouse IGFBP-3 Quantikine ELISA Kit
The Quantikine Mouse IGFBP-3 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse IGFBP-3 in cell culture supernates and plasma. It contains NS0-expressed recombinant mouse IGFBP-3 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse IGFBP-3 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse IGFBP-3.

Specificity
Natural and recombinant mouse IGFBP-3. This kit detects full-length and fragmented mouse IGFBP-3. It also detects IGF-I, IGF-II, IGF-I/ALS, and IGF-II/ALS complexed IGFBP-3.
Cross-reactivity
< 0.5% cross-reactivity observed with available related molecules. < 50% cross-species reactivity observed with species tested.
Interference
Interference observed with 1 or more available related molecules.
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 known concentration were tested in separate assays to assess inter-assay precision.

Background: IGFBP-3
IGFBP-3 (Insulin-like growth factor binding protein-3) modulates the biological activity of IGF. It circulates in a ternary complex with IGF and the acid-labile subunit (ALS). Proteolysis of IGFBP-3 by tissue plasminogen activator (tPA), a disintegrin and metalloproteases (ADAMs), and prostate specific antigen (PSA) contributes to IGFBP-3 degradation or a reduction in its affinity for IGF. The majority of soluble IGFBP-3 found in circulation is secreted from hepatic non-parenchymal cells. IGFBP-3 potentiates EGF-EGFR-mediated cell growth, modulates adipogenesis, and regulates TGF-beta signaling, DNA damage, apoptosis, autophagy, and gene transcription.
