Free Metanephrines in Plasma
Free Metanephrines in Plasma Cells derived form neuroendocrine tumours (e.g. Pheochromcytoma) are known to produce Catecholamines which are secreted episodically via vesicles into the blood stream. But beside this a small portion of the Catecholamines is metabolized inside the cells to the corresponding Catecholamines metabolites – namely Metanephrine, Normetanephrine and 3-methoxy-tyramine – which are secreted at low levels continuously into the blood stream. Recent studies and publications have shown that the quantification of these plasma free metanephrine (fMN) and plasma free normetanephrine (fNMN) is the most accurate biochemical marker for the clinical diagnosis of Pheochromocytoma and follow-up of pheochromocytoma patients. LDN has developed enzyme immunoassays and isotopic assays for the quantitative determination of fMN and fNMN in human plasma with extraction. The assays show the following common features:

speed and ease of use
cost-effective
for in-vitro diagnostic and research applications
wide standard ranges
available as ELISA and RIA (with 15 weeks shelf-life)
the ELISA is automatable
freedom from drug interferences
excellent correlation with HPLC
single and multi parameter kits available

Histamine ELISA
Histamine ELISA

In humans, histamine (β-imidazole ethylamine) is one of the most important mediators and takes part in the initial phase of an anaphylactic reaction (“immediate type” allergy).
It is produced by basophils and by mast cells found in connective tissues .
Of clinical interest is also the quantification of the histamine release from basophilic leucocytes in allergies (please refer to the add-on kit Histamine Release; reference no. BA E-1100).

The Histamine ELISA (BA E-1000) measures quantitively Histamine levels in plasma and urine and in conjuction with the add-on kit BA E-1100 the release of Histamine from whole blood.
The assay is intended for in-vitro diagnosis and research applications

About Us

Company details
LDN was founded in 1996 in Nordhorn, Germany, with the aim to develop, manufacture and supply specialty in-vitro diagnostics test systems and innovative technologies to the clinical and research laboratory markets. From the beginning the determination of biogenic amines with immunological test systems was in the core of our business – where we are nowadays the world wide market leader. Integral part of this success are e.g. our assays for the quantitative determination of free metanephrines in plasma, the catecholamines, histamine and serotonin.

This positive outcome encouraged us to expand our business to related diagnostic areas such as food safety (HistaSure™ Fish Rapid Test, HisQuick™), food intolerance, neurotransmitters and amino acids. Next, LDN introduced a comprehensive endocrinological panel, especially also for niche parameters e.g. free testosterone, 17-OH-progesterone, chromogranin A, DHT, estrone. We continue to innovate on a consistent base, developing on average 5-7 new products a year.

LDN products are distributed in over 80 countries by a network of OEM partners and distributors and in North America through our daughter company Rocky Mountain Diagnostics. Our focus aside from selling great products is to support them. Our concern is your satisfaction and confidence in using the latest and newest technologies from our company. Our team is highly trained and experienced as both end users and developers. We believe this philosophy gives our support, in addition to efficiency, a personal touch exclusive to our products. We guarantee a 24-hour turnaround time on most all technical inquiries. Our company is privately owned, thus making our customers the number one priority. As such, we provide our customers with the best possible products and services.

We have meanwhile finished our facility expansion which increased our laboratory, office and warehouse space from 3,600 to 16,000 sq.ft.
Aside from spacious production facilities, R&D and QC laboratories, we have also doubled our refrigeration capacity from 900 to 1,600 sq.ft. At our disposal is also a seminar room and a fully equipped customer training area.
We look forward to having you as our guests in our new home!
