Product Summary

The Quantikine Human Amphiregulin Immunoassay is a 4.5 hour solid phase ELISA designed to measure human Amphiregulin in cell culture supernates, cell lysates serum, plasma, saliva, and urine. It contains E. coli-derived recombinant human Amphiregulin and has been shown to accurately quantitate the recombinant factor. Results obtained with natural human Amphiregulin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human Amphiregulin.

Precision

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. Assays were performed by at least three technicians using two lots of components

Cell Culture Supernates, Cell Lysates, Serum, EDTA Plasma, Heparin Plasma, Saliva, Urine

	Intra-Assay Precision			Inter-Assay Precision
Sample	1	2	3	1	2	3
n	20	20	20	20	20	20
Mean (pg/mL)	102	314	631	99.4	308	614
Standard Deviation	5.63	10.5	22.4	9.85	20.5	28.8
CV%	5.5	3.3	3.5	9.9	6.7	4.7

Recovery

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

Sample Type	Average % Recovery	Range %
Cell Culture Media (n=4)	95	88-101
EDTA Plasma (n=4)	93	82-105
Heparin Plasma (n=4)	94	82-103
Saliva (n=4)	104	98-113
Serum (n=4)	95	85-103
Urine (n=4)	88	75-99

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Amphiregulin were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: Amphiregulin

Amphiregulin (AR) is an EGF family growth factor that is released as a soluble protein following proteolytic cleavage of its transmembrane precursor. Amphiregulin is expressed by numerous carcinoma cell lines and epithelial cells of the colon, stomach, breast, ovary and kidney. It acts through ErbB family of receptor to stimulate the proliferation of keratinocytes, mammary epithelial cells, fibroblasts, astrocytes and glial cells. Amphiregulin can also inhibit the growth of certain tumor cells.

Alternate Names:

Amphiregulin; AR; AREG; AREGB; Colorectum cell-derived growth factor; CRDGF; MGC13647; schwannoma-derived growth factor; SDGF

Assay Procedure

Refer to the product for complete assay procedure.

The conjugate must remain at 2-8 °C during use. Bring all other reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.

Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

50 µL Assay Diluent

Add 50 µL of Assay Diluent to each well.

50 µL Standard, Control, or Sample

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.
Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

200 µL cold Conjugate

Add 200 µL of cold Conjugate to each well. Cover with a new plate sealer, and incubate at 2-8 °C for 2 hours on the benchtop.
Aspirate and wash 4 times.

200 µL Substrate Solution

Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

50 µL Stop Solution

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.

FAQs

Assay Diluent RD1-14 contains visible precipitate. Is this acceptable to use?
- A small amount of precipitate is expected and acceptable in Assay Diluent RD1-14. Variability has been observed between vials and diluent lots. It may not fully resolubilize but this will not impact assay performance. It is not recommended to filter the precipitate.
