Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of bovine interferon-tau in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	85
	Range %	82-92

Recovery

The recovery of bovine interferon-tau spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Description

The Bovine interferon-Tau (IFN-tau) ELISA Kit is an excellent choice for accurate quantification of bovine interferon-Tau in serum, plasma, and tissue homogenates. It provides a detection range of 6.25 pg/mL-400 pg/mL and a sensitivity of 1.56 pg/mL. This kit employs a Sandwich detection mechanism, which involves capturing the IFN-tau protein between two layers of antibodies: a capture antibody coated on the plate and a detection antibody that binds to the protein. This dual binding increases specificity and sensitivity, ensuring precise measurements. The assay requires 50-100 μL of sample and has a duration of 1-5 hours, with detection at 450 nm wavelength. This kit has been cited in over 3 research papers.

Target Background

Function
(From Uniprot)

Paracrine hormone primarily responsible for maternal recognition of pregnancy. Interacts with endometrial receptors, probably type I interferon receptors, and blocks estrogen receptor expression, preventing the estrogen-induced increase in oxytocin receptor expression in the endometrium. This results in the suppression of the pulsatile endometrial release of the luteolytic hormone prostaglandin F2-alpha, hindering the regression of the corpus luteum (luteolysis) and therefore a return to ovarian cyclicity. This, and a possible direct effect of IFN-tau on prostaglandin synthesis, leads in turn to continued ovarian progesterone secretion, which stimulates the secretion by the endometrium of the nutrients required for the growth of the conceptus. In summary, displays particularly high antiviral and antiproliferative potency concurrently with particular weak cytotoxicity, high antiluteolytic activity and immunomodulatory properties. In contrast with other IFNs, IFN-tau is not virally inducible.
