Instant ELISA Kit for Interferon Alpha (IFNa)

• Product Name Alternative:

  IFNA1; IFL; LeIF D; IFN; IFN-Alpha; IFNA13; IFN-A; IFNAP22; IFN-Alpha 1b; Interferon Alpha 1b; Interferon, Leukocytic; IFN, Leukocyte; Interferon alpha-D

• Applications:

  Enzyme-linked immunosorbent assay for Antigen Detection.

• Assay Principle:

  The test principle applied in this kit is enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Instant Interferon Alpha (IFNa) . Standards or samples and HRP-labeled detection antibody specific to Instant Interferon Alpha (IFNa) (Detection Reagent A) are then added to the appropriate microtiter plate wells. Next, TMB substrate solution is added, only those wells that contain Instant Interferon Alpha (IFNa), and HRP-labeled detection antibody 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 Instant Interferon Alpha (IFNa) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

• Assay Protocol:

  1. Prepare all reagents, samples and standards;
  2. Add 50µ L standard or sample and 50µ L Detection Reagent A to each well. Incubate 1 hours at 37° C;
  3. Aspirate and wash 3 times;
  4. Add 90µ L Substrate Solution. Incubate 10-20 minutes at 37° C;
  5. Add 50µ L Stop Solution. Read at 450nm immediately.
  

• Assay Performance Time:

  1H, 10min

• Sample Type:

  Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids

• Detection Range:

  15.6 - 1000 pg/mL

• Precision:

  Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Instant Interferon Alpha (IFNa) were tested 20 times on one plate, respectively.
  Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Instant Interferon Alpha (IFNa) were tested on 3 different plates, 8 replicates in each plate.
  CV (%) = SD/meanX100
  Intra-Assay: CV<10%
  Inter-Assay: CV<12%
  

• Sensitivity:

  The minimum detectable dose of this kit is typically less than 5.4pg/mL

• Stability:

  The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
  To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

• Specificity:

  This assay has high sensitivity and excellent specificity for detection of Instant Interferon Alpha (IFNa) .
  No significant cross-reactivity or interference between Instant Interferon Alpha (IFNa) and analogues was observed.

• Method:

  Double-Antibody Sandwich

• Organism Species:

  Chicken (Gallus)

• CAS Number:

  7732-18-5
