CLIA Kit for Luteinizing Hormone (LH)

• Product Name Alternative:

  ICSH; Lutropin; Interstitial Cell Stimulating Hormone

• Applications:

  Chemiluminescent immunoassay for Antigen Detection.

• Assay Principle:

  The microplate provided in this kit has been pre-coated with a monoclonal antibody specific to Luteinizing Hormone (LH) . A competitive inhibition reaction is launched between biotin labeled Luteinizing Hormone (LH) and unlabeled Luteinizing Hormone (LH) (Standards or samples) with the pre-coated antibody specific to Luteinizing Hormone (LH) . 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 Luteinizing Hormone (LH) 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 Luteinizing Hormone (LH) 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 and other biological fluids

• Detection Range:

  117.19 - 30000 pg/mL

• Precision:

  Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Luteinizing Hormone (LH) were tested 20 times on one plate, respectively.
  Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Luteinizing Hormone (LH) 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 59.35pg/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 Luteinizing Hormone (LH) .
  No significant cross-reactivity or interference between Luteinizing Hormone (LH) and analogues was observed.

• Method:

  Competitive Inhibition

• Organism Species:

  Mus musculus (Mouse)
