Product Summary

The Parameter TXB₂ Immunoassay is a 3.5 hour competitive enzyme immunoassay designed to measure TXB₂ in cell culture supernates, serum, plasma, and urine.

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

Recovery

The recovery of TXB₂ spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type	Average % Recovery	Range %
Cell Culture Media (n=4)	98	88-110
EDTA Plasma (n=4)	94	86-105
Heparin Plasma (n=4)	97	87-107
Serum (n=4)	98	86-111
Urine (n=4)	98	84-111

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of TXB₂ were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
