The Quantikine Human Survivin immunoassay is a 4.5 hour solid phase ELISA designed to measure human Survivin in cell culture supernates, serum, plasma, and urine. It contains E. coli-expressed recombinant human Survivin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Survivin 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 human Survivin.
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.
Serum, EDTA Plasma, Heparin Plasma
Cell Culture Supernates, Urine
The recovery of Survivin spiked to levels throughout the range of the assay in various matrices was evaluated.

Heparin Plasma (n=4)
To assess the linearity of the assay, samples spiked with high concentrations of Survivin were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Survivin is a member of the Inhibitor of Apoptosis (IAP) gene family and contains a single BIR domain. Increased survivin expression at the G2/M checkpoint contributes to tissue homeostasis and differentiation during embryonic and fetal development. Increased expression in differentiated adult tissues, however, frequently results in unchecked cell survival, resulting in cancer. Survivin can protect cells from caspase-induced apoptosis activated in mitosis presumably by binding to Caspase-3, -7, and -9.
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.
