About LDN

LDN was founded in 1996 in Nordhorn, Germany, with the aim of developing and manufacturing specialty in vitro test systems. The determination of biogenic amines by immunological methods has remained the core of its work. Alongside its catalogue kits, the company states contract development and manufacturing activity, and takes part in external quality assessment schemes such as INSTAND, RfB, ARVECON and FAPAS.

What LDN makes

  • Biogenic amines — catecholamines, plasma and urine metanephrines, serotonin, histamine: the company's founding area. → ELISA kits
  • Neuroendocrine markers — chromogranin A and 5-HIAA, alongside neurotransmitters and amino acids.
  • Endocrinology — testosterone and free testosterone, DHEA, 17-OH-progesterone, cortisol, melatonin, AMH, with saliva-specific versions.
  • Food control — kits and control materials for histamine in food, including fish controls. → Biochemicals

LDN references in the CABRU catalogue

Of the 102 LDN references in the CABRU catalogue, 97 are ELISA kits. Fourteen belong to the Fast Track line, which shortens run time compared with the extended protocol for the same analyte. Several references exist in more than one version depending on the matrix — plasma, urine, saliva — and for histamine the catalogue also includes control materials for the food matrix.

Application areas

Research and routine laboratory work in endocrinology, neuroscience and neuroendocrine biomarkers; stress and circadian rhythm studies through salivary cortisol and melatonin; food safety and intolerance, particularly for histamine. These are kits chosen from the analyte and the matrix, not from the instrument platform.

Analyte, matrix, protocol: the three questions

LDN references look alike by name and differ on three points: which analyte, on which matrix, and with which protocol length. A metanephrine assay on plasma is not the same as on urine, and the Fast Track version is not the same kit as the extended one. CABRU asks for those three details before quoting, which is why the quote comes back with the correct code first time.
