ISOQUANT® Isoaspartate Detection Kit Technical Bulletin

Instructions for Use of Product(s)
MA1010

Literature # TBI001

The ISOQUANT® Isoaspartate Detection Kit is intended for quantitative detection of isoaspartic acid residues in proteins and peptides, which can result from the gradual, nonenzymatic deamidation of asparagine or rearrangement of aspartic acid residues during storage or handling.

The ISOQUANT® Kit provides reagents for deamidation detection using an HPLC method. The amount of isoaspartic acid to target protein is determined by comparison with reactions performed using a reference standard peptide.
