Product Summary
The Quantikine Human TGF-alpha Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human TGF-alpha in cell culture supernates, serum, plasma, and human milk. It contains E. coli-expressed recombinant human TGF-alpha and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human TGF-alpha 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 naturally occurring human TGF-alpha.

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

Recovery

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

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 97 92-108
EDTA Plasma (n=4) 99 88-114
Heparin Plasma (n=4) 103 88-114
Serum (n=4) 103 96-114
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of TGF-alpha were serially diluted with the 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: TGF-alpha
TGF-alpha is a member of the EGF family of cytokines that are synthesized as transmembrane precursors with soluble forms released by proteolytic cleavage. Membrane-bound proTGF-alpha is biologically active and plays a role in mediation of cell-cell adhesion and in juxtacrine stimulation of adjacent cells. Expression of TGF-alpha is widespread in tumors and transformed cells. TGF-alpha is also expressed in normal tissues during embryogenesis and in adult tissues, including pituitary, brain, keratinocytes and macrophages. TGF-alpha binds and activates the EGF receptor. It induces fibroblast proliferation, epithelial development, keratinocyte migration, and angiogenesis.

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. 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.
  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 2 hours.
  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
