Product Summary
The Quantikine Mouse/Rat RGM-C/Hemojuvelin Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse and rat RGM-C in cell culture supernates, tissue homogenates, serum, and plasma. It contains NS0-expressed recombinant mouse RGM-C and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant factor accurately. Results obtained using natural RGM-C showed dose-response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural RGM-C.

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 a known concentration were tested in separate assays to determine inter-assay precision. Assays were performed by at least three technicians using two lots of kit components.

The recovery of mouse/rat RGM-C spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=4) 98 85-110
EDTA Plasma (n=4) 100 80-120
Heparin Plasma (n=4) 100 83-116
Serum (n=4) 105 88-120
To assess the linearity of the assay, samples containing high concentrations of RGM-C were serially 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: RGM-C/Hemojuvelin
The repulsive guidance molecule (RGM) family of molecules contains three uniquely structured GPI-linked glycoproteins that participate in a variety of activities. Termed RGM-A, -B and -C, they are 40-45 kDa in size, show generally nonoverlapping fetal expression patterns, and serve as BMP-4 receptors. RGM-A and -C are plasma membrane bound, while RGM-B is generally microsomal in location. RGM-A and -B are associated with neurons, while RGM-C regulates skeletal muscle and hepatocyte function.

    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. 50 µL Assay Diluent
    4.   Add 50 µL of Assay Diluent to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 100 µL Conjugate
    9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
    10.   Aspirate and wash 4 times.

    11. 100 µL Substrate Solution
    12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 100 µL Stop Solution
    14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
