Fen-activ[R] is a unique iron multi-amino acid chelate which has been clinically proven to be well tolerated, highly bioavailable and has been studied at the atomic level to enable a definitive distinction to be made between this full-reacted mineral chelate and other un-reacted blends or irritating, low-value inorganic salts.
The numerous advantages of the fluorescent lanthanide chelates over conventional fluorescent probes have been summarized elsewhere (1-6,15).
One way to alleviate the problem is to use low-quantum yield chelates (30), which hence also give less background.
