摘要:
The present invention relates to a buffering composition, more closely a composition comprising porous matrix-enclosed buffering agent(s) giving a stabilisation of pH when applied in for example aqueous environment.The composition comprises buffering agent(s) enclosed in a first porous matrix with an impenetrability corresponding to a fractionation range for globular proteins and peptides of
