|Radioimmunoassay for naringin and related flavanone 7-neohesperidosides using a tritiated tracer.[Reference: WebLink]|
METHODS AND RESULTS:
A radioimmunoassay (RIA) that can be used for the quantification of naringin in grapefruit tissues is described. The assay utilizes antisera raised against a naringin 4-O-(carboxymethyl)oxime hapten. The tracer used was a 3H derivative of naringin that was stable for at least 8-12 months. The detection limit of the assay is 0.2 ng or 2 ppb of naringin. Only flavanone 7-Neohesperidosides are detected by the assay and naringin is the most reactive compound; the isomeric 7-rutinosides do not interfere. The RIA has a high sample throughput and requires only dilution of crude extracts.
The reliability and reproducibility of the assay are demonstrated by intra- and interassay variability of 2.3% and 5.0% cv, respectively.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
