Recovery

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

Sample Type	Average % Recovery	Range %
Cell Culture Media (n=4)	99	95-103
EDTA Plasma (n=4)	104	94-114
Heparin Plasma (n=4)	103	95-115
Serum (n=4)	103	86-115

Linearity

To assess the linearity of the assay, samples spiked with high concentrations of AFP were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: alpha-Fetoprotein/AFP

alpha-Fetoprotein (AFP), is albuminoid superfamily protein that is synthesized in the fetus primarily by the liver, yolk sac, and tissues of gastrointestinal origin. It is one of the earliest markers of the hepatocyte lineage. AFP acts as a carrier protein for steroids, bilirubin, fatty acids, retinoids, and flavonoids. In addition, it can exert immunosuppressive activity, regulate cell proliferation and apoptosis, initiate intracellular signaling, and contribute to cell invasion. Altered levels of both fetal and maternal AFP have been associated with hypothyroidism, autoimmune disorders, and heart defects. Low maternal serum AFP levels are associated with a higher incidence of Down syndrome, whereas higher levels are associated with spina bifida and anencephaly. Elevated AFP levels are also coincident with liver, stomach, and germ cell cancers.

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.

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.

100 µL Assay Diluent

Add 100 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.
Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

200 µL Conjugate

Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
Aspirate and wash 4 times.

200 µL Substrate Solution

Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. 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.
