title: A comparison of fluorescamine and o-phthaldialdehyde as effective blocking reagents in protein sequence analyses by the Beckman sequencer.
abstract: Use of o-phthaldialdehyde to chemically reduce the newly generated amino termini responsible for the progressively increasing background during an extended amino acid sequence analysis in a liquid phase sequencer has been described. The results have been compared with Fluram blocking using apomyoglobin and rabbit C-reactive protein as standard and unknown samples, respectively.
