Description

Background information

An excellent acid-labile resin for the continuous flow and batch Fmoc SPPS of peptide acids.

It is derived from amino PEGA resin by derivatization with the TFA-labile 4-hydroxymethylphenoxyacetic acid linker. For further information, please refer to the product entry for amino PEGA resin (855015).Note: PEGA resins are supplied swollen in ethanol, with 1g dry resin corresponding to approximately 15 mL of swollen resin. As the beads of PEGA resins become very sticky and easily damaged when shrunk or dried, they are best handled in a swollen state. To use, the appropriate amount of swollen resin should be weighed into a reaction vessel and any residual ethanol removed by copious washings with the appropriate solvent or solvent mixture. After peptide assembly, the resin should be washed with DCM and transferred to the cleavage vessel. Excess DCM can be removed under vacuum, and the shrunk resin treated with the TFA cocktail.

The characteristics of the swollen resin, its robustness and high permeability enables its use in both batch and continuous flow synthesis apparatus.

The product number for this product was previously 01-64-0102.
