Product Summary
The Quantikine Human Leptin Immunoassay is a 3.5 hour solid phase ELISA designed to measure soluble human Leptin in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human Leptin and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate recombinant Leptin accurately. Results obtained measuring natural human Leptin showed dose-response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human Leptin.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

The recovery of Leptin spiked to three different levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=5) 98 94-102
Citrate Plasma (n=5) 95 87-105
EDTA Plasma (n=5) 99 85-112
Heparin Plasma (n=5) 90 81-100
Serum (n=5) 95 89-109
To assess the linearity of the assay, cell culture media samples spiked with high concentrations of Leptin and natural serum/plasma samples were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: Leptin/OB
Leptin is a product of the mouse obese gene. Mice with mutations in the obese gene that block the synthesis of leptin are obese and diabetic, and have reduced activity, metabolism, and body temperature. Rat leptin shares approximately 96% and 82% sequence identity with the mouse and human protein, respectively. The expression of leptin mRNA is restricted to adipose tissue.
    • Entrez Gene IDs
      3952 (Human); 16846 (Mouse); 25608 (Rat);
    • Alternate Names
      FLJ94114; LEP; leptin (murine obesity homolog); leptin (obesity homolog, mouse); leptin; OB; Obese protein; obese, mouse, homolog of; Obesity factor; OBOBS;

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 100 µL Assay Diluent
    4.   Add 100 µL of Assay Diluent to each well.

    5. 100 µL Standard, Control, or Sample
    6.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 200 µL Conjugate
    9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 1 hour.
    10.   Aspirate and wash 4 times.

    11. 200 µL Substrate Solution
    12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

    13. 50 µL Stop Solution
    14.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
