Organization: ASTM International
Publication Date: 1 January 1995
Status: inactive
Page Count: 4
scope:

1.1 This test method covers the determination of isoaspartic acid residues in a protein or peptide sample. This test method is applicable for the determination of isoaspartic acid residues in a sample in the range of 2.5-50 [mu]mol/L. Higher concentrations can be determined following dilution. The reported lower range is based on single-operator precision.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
