Regenerating islet-derived 3-alpha Plasma
For the quantitative measurement of REG3α. REG3α, an anti-inflammatory/anti-bacterial protein expressed in Paneth cells within the epithelium of the small intestine, has been shown to be elevated in medical conditions where immune dysregulation causes damage to the mucosal epithelial barrier.
The assay for quantification of REG3α is a sandwich ELISA performed in a microtiter plate format. Conversion of a chromogenic substrate produces a color, the intensity of which is proportional to the concentration of REG3α in the sample material. A standard curve is used to calculate the concentration of REG3α in each of the test samples. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
Specific to human REG3α.

|plasma||30147||83520||Yes||1 mL||16.0-1000.0 ng/mL||
The result is reported in ng/mL. The assay range is approximately 29.5 to 1000.0 ng/mL. The reference range for a healthy population is less than 89.0 ng/mL. However it should be noted that these ranges are obtained from a limited population of apparently healthy adults and are not diagnostic thresholds.
Ship Monday through Friday. Friday shipments must be labeled for Saturday delivery. All specimens must be labeled with patient's name and collection date.
