【評論內容】(B) Borate gels 課本敘述 1. immobilised alkyl boronic acids.2. selective affinity for 1,2- or 1,3-diol groupings ( catechol-containing molecules=dopamine、sugars、glycosides)3. The analyte is loaded onto the gel in a buffer at ca pH 7.0 4. The complex formed can be broken down using a mildly acidic eluent such as 0.1 M acetic acid.5. Applied to the determination of dopamine, adrenaline and noradrenaline in plasma and to the determination of the extent of reaction of glucose with serum albumin as a measure of glucose fluctuations with time in diabetics33.以...
