Product Summary
The Quantikine Mouse IL-34 immunoassay is a 4.5 hour solid-phase ELISA designed to measure IL-34 in mouse cell culture supernates, tissue lysates, serum, and plasma. It contains NS0-expressed recombinant mouse IL-34 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse IL-34. Results obtained using natural mouse IL-34 showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse IL-34.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of kit components.

The recovery of IL-34 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 98 92-103
EDTA Plasma (n=4) 100 85-109
Heparin Plasma (n=4) 103 99-110
Serum (n=4) 100 95-107
To assess the linearity of the assay, samples spiked with high concentrations of IL-34 in each matrix were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-34

Interleukin 34 (IL-34; also known as uncharacterized protein C16orf77) is secreted as a homodimer consisting of 39 kDa monomers. It belongs to no known cytokine family. Human IL-34 is synthesized as a 242 amino acid (aa) precursor that contains a 20 aa signal sequence and a 222 aa mature chain. The mature chain contains one potential site of N-linked glycosylation. Human IL-34 is 71% identical to mouse IL-34 on the amino acid level.

IL-34 is expressed in various tissues, including the heart, brain, liver, kidney, spleen, thymus, testes, ovary, small intestine, prostate, and colon, and is most abundant in the spleen. The receptor for IL-34 is colony-stimulating factor 1 receptor (CSF-1R). IL-34 stimulates monocyte proliferation. In functional studies, IL-34, like CSF-1, the other ligand for CSF-1R, stimulated phosphorylation of extracellular signal-regulated kinase-1 and -2 (ERK1/2) in human monocytes. In addition, IL-34 promoted the formation of the colony-forming unit-macrophage (CFU-M), a macrophage progenitor, in human bone marrow cultures.

    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.
