ELISA Kit for Transforming Growth Factor Beta 1 (TGFb1)

  • Product Name Alternative:

    TGF-B1; CED; DPD1; LAP; Camurati-Engelmann Disease; Latency-associated peptide
  • Applications:

    Enzyme-linked immunosorbent assay for Antigen Detection.
  • Assay Principle:

    This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Transforming Growth Factor Beta 1 (TGFb1) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Transforming Growth Factor Beta 1 (TGFb1) and unlabeled Transforming Growth Factor Beta 1 (TGFb1) (Standards or samples) with the pre-coated antibody specific to Transforming Growth Factor Beta 1 (TGFb1) . 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 Transforming Growth Factor Beta 1 (TGFb1) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Transforming Growth Factor Beta 1 (TGFb1) in the sample.
  • 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 90µ L Substrate Solution. Incubate 10-20 minutes at 37° C;
    7. Add 50µ L Stop Solution. Read at 450 nm immediately.
  • Assay Performance Time:

    2H
  • Sample Type:

    Serum, platelet-poor plasma, tissue homogenates, cell culture supernates and other biological fluids
  • Detection Range:

    2.47 - 200 pg/mL
  • Precision:

    Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Transforming Growth Factor Beta 1 (TGFb1) were tested 20 times on one plate, respectively.
    Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Transforming Growth Factor Beta 1 (TGFb1) 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 0.83pg/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 Transforming Growth Factor Beta 1 (TGFb1) .
    No significant cross-reactivity or interference between Transforming Growth Factor Beta 1 (TGFb1) and analogues was observed.

  • Method:

    Competitive Inhibition
  • Organism Species:

    Bos taurus; Bovine (Cattle)
  • CAS Number:

    7732-18-5
