NGAL products for research

NGAL (neutrophil gelatinase-associated lipocalin, lipocalin-2) is a small protein expressed in neutrophils and certain epithelia, including the renal tubules. In humans, renal expression of NGAL is dramatically increased after kidney injury, and NGAL is released into both urine and plasma. Evidence is rapidly accumulating to show that NGAL also rises in animals after kidney injury.

BioPorto offers three types of products for NGAL determination

The wide applications of NGAL measurement include:

Basic research   |   Toxicology and Drug development   |   Medical research 


Basic and Medical research

NGAL undergoes an early and dramatic up-regulation in renal tubular cells after kidney injury from a variety of causes. Rises of NGAL concentrations in urine, plasma or serum can be used in basic research, medical research and preclinical studies to detect the extent of kidney injury.

NGAL determination could also be used to detect kidney injury or disease in pets and farm animals.

Toxicology and Drug development

NGAL is the first kidney injury or toxicity biomarker that can be measured in all the standard animal models of basic research, medical research and drug development. In recent years NGAL has been shown to be perhaps the earliest biomarker to respond to acute kidney injury in humans. After such injury, NGAL levels rise quickly and markedly in both urine and blood, showing a wide response range in comparison with other proposed biomarkers of kidney injury.

BioPorto's animal NGAL ELISA kits can be used in preclinical studies to detect rises in NGAL concentrations in urine and blood and hence the extent of renal injury, including nephrotoxic injury. The applications of BioPorto's animal NGAL ELISA kits in drug development range from drug discovery to preclinical toxicity testing. BioPorto also offers human NGAL assays (Clinical Chemistry and ELISA) which can be used in clinical studies, e.g. to detect nephrotoxicity in the relevant phases of clinical trials.

Animal line

Important applications of NGAL measurement for the pharmaceutical industry are:

  • Safety biomarker - NGAL levels rise from baseline if the kidney is injured
  • Efficacy biomarker - NGAL levels fall if kidney damage treated effectively
