CLIA Kit for Fibroblast Growth Factor 18 (FGF18)

• Product Name Alternative:

  ZFGF5

• Applications:

  Chemiluminescent immunoassay for Antigen Detection.

• Assay Principle:

  The microplate provided in this kit has been pre-coated with a monoclonal antibody specific to Fibroblast Growth Factor 18 (FGF18) . A competitive inhibition reaction is launched between biotin labeled Fibroblast Growth Factor 18 (FGF18) and unlabeled Fibroblast Growth Factor 18 (FGF18) (Standards or samples) with the pre-coated antibody specific to Fibroblast Growth Factor 18 (FGF18) . After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Fibroblast Growth Factor 18 (FGF18) in the sample. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is reverse proportional to the Fibroblast Growth Factor 18 (FGF18) level in the sample or standard.

• Assay Protocol:

  1. Prepare all reagents, samples and standards;
  2. Add 50µ L standard or sample to each well.
          And then add 50µ L prepared Detection Reagent A immediately.
          Shake and mix. Incubate 1 hour at 37° C;
  3. Aspirate and wash 3 times;
  4. Add 100µ L prepared Detection Reagent B. Incubate 30 minutes at 37° C;
  5. Aspirate and wash 5 times;
  6. Add 100µ L Substrate Solution. Incubate 10 minutes at 37° C;
  7. Read RLU value immediately.
  

• Assay Performance Time:

  2H

• Sample Type:

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

• Detection Range:

  31.2 - 500 pg/mL

• Precision:

  Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Fibroblast Growth Factor 18 (FGF18) were tested 20 times on one plate, respectively.
  Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Fibroblast Growth Factor 18 (FGF18) 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 13.3pg/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 Fibroblast Growth Factor 18 (FGF18) .
  No significant cross-reactivity or interference between Fibroblast Growth Factor 18 (FGF18) and analogues was observed.

• Method:

  Competitive Inhibition

• Organism Species:

  Homo sapiens (Human)
