Products specifications
Species Guinea pig
Format 96T
Sample Type Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.
Assay Length 4.5 h
Detection Range 15.63-1000pg/mL. The standard curve concentrations used for the ELISA’s were 1000pg/mL, 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL, 31.25pg/mL, 15.63pg/mL
Sensitivity 5.6pg/mL
Specificity This assay has high sensitivity and excellent specificity for detection of Interferon Alpha (IFNa). No significant cross-reactivity or interference between Interferon Alpha (IFNa) and analogues was observed.
Intra-Assay Precision <10%
Inter-Assay Precision <12%
Storage Temperature -20 °C
Shipping Conditions 2-8 °C
Handling Instruction The activity loss rate (stability) of this kit is less than 5% within the expiration date under appropriate storage conditions. To minimize extra influence on the stability, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. When not in use, kit components should be refrigerated. All reagents should be brought to room temperature before use. It is recommended that all standards, controls, and samples be run in duplicate. Do not mix or interchange different reagent lots from various kit lots.
Test Principle The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Interferon Alpha (IFNa). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Interferon Alpha (IFNa). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Interferon Alpha (IFNa), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Interferon Alpha (IFNa) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
Notes All kits are custom made on-demand. Please allow 10-15 working days for production and 2-3 days for shipment.

Instruction manual1

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Interferon Alpha (IFNa) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
