Innovative solid phase extraction (SPE) technology from Supelco, utilizes phospholipid retention mechanism based on highly selective interaction between proprietary zirconia ions (bonded to the stationary phase) and the phosphate moiety consistent with phospholipids and proteins.
The most popular reagent for cleavage of peptides from Boc-based resins is anhydrous HF. Of all the cleavage procedures HF appears to be the most versatile and least harmful to a wide variety of peptides synthesized on Boc-based resins.
Supel Tox AflaZea SPE produced exceptional analyte recoveries with good reproducibility for all aflatoxins while requiring less than half the sample volume required by competing products.HPLC analysis of all spiked samples after SPE cleanup showed that all compared SPE cartridges
