    Abstract: A composition comprising neutrophil gelatinase-associated lipocalin (NGAL), which has been enriched from urine, has a molecular weight of about 24.9 kDa to about 25.9 kDa, and comprises a plurality of isoforms having isoelectric points (pIs) ranging from about 5.9 to about 9.1; a composition comprising NGAL, which has been enriched from recombinant Chinese hamster ovary (CHO) cells, has a molecular weight of about 25.9 kDa to about 27.9 kDa, and comprises a plurality of isoforms having pIs ranging from about 5.6 to about 9.1; a method of obtaining from urine a composition comprising a plurality of isoforms of NGAL, which method comprises enriching NGAL in urine without separating molecules based on charge; a method of obtaining from recombinant CHO cells a composition comprising a plurality of isoforms of NGAL, which method comprises enriching NGAL in a composition without separating molecules based on charge; and a method of analyzing NGAL isoforms enriched from urine or recombinant CHO cells comprising analyzing an enriched composition comprising NGAL isoforms by two-dimensional electrophoresis and Western blot.
