About us

Nordic was established in 1934 as a firm for manu­facturing and trade of pharma­ceutical and chemical compounds. The focus shifted to immunology and the production of antisera became the main activity. Cooperation with the Institutes of the Dutch Health Organisation for Applied Scientific Research (TNO) resulted in many specific antisera to human, mouse, monkey and rat immuno­globulin classes and their subclasses. These are still important items in the product range of Nordic. Of interest may also be a wide range of polyclonal antisera to other serum proteins of different animal species.Early techniques were based on precipi­tation reactions of antisera with the antigen. Although under­estimated nowadays, immuno­electrophoresis, single and double radial immuno­diffusion (Mancini, Ouchterlony) are still valuable techniques. Along with the development of more sensitive techniques Nordic Laboratories produce fluorescent and horse­radish peroxidase conjugates as well as biotin conjugates for labels of the customers own choice.

Over the years we have established working reference standards of reactivity, purity and stability, which are permanently reviewed in the light of current progress. Our aim is to provide the customer a wide scale of basic immuno­logical products of high quality, also suited for more traditional techniques and small-scale applications, as well as support based on many years of experience

Today we offer a range of over 1700 products for fundamental and applied research of human and veterinary systems. It includes a unique series of polyclonal antisera against enzymes as unlabelled IgG fractions, biotin conjugates and affinity purified antibody fractions.

General information

Nordic Immunological Laboratories offer a range of immunologic reagents including:

precipitating polyclonal antisera

· polyclonal reagents for immunofixation

·cytochemical grade purified IgG(7S) fractions of poly­clonal antisera and purified polyclonal antibodies

·monoclonal antibodies, fluorescent, biotin and peroxidase immuno­conjugates

·polyclonal fluorescent, biotin and peroxidase immunoconjugates

·normal sera, milk and purified proteins

Contrary to still widely held opinion, immuno­logic reagents are usually not general purpose reagents for universal use. Different tech­niques and even different modifi­cations or arrangements of an otherwise established method frequently result in different require­ments for the reagents. These differences are not only associated with the properties of the antibody, but also with the characte­ristics of other humoral or cellular components under the conditions of the test system.

Inter-species cross-reactivity is a normal feature of antibodies to animal proteins, since homologous proteins of different species frequently share antigenic determinants. 

Although cross-reactivity of polyclonal antisera can in principle be removed by cross-adsorption, it is frequently difficult to achieve this even for a single species and it may result in a significant loss of required antibody activity. On the other hand, it can be used to advantage if a comparable primary antiserum is not available and the reaction pattern is correctly recognized and understood.

For use in mixed mouse/human test systems Nordic makes available 7S fractions and immunoconjugates from a goat antiserum to all known mouse Ig-isotypes, cross-adsorbed to minimize reactivity with any component of the human Ig system. The same series of products also exist for the mixed rat/human system.

Antisera, labelled or unlabelled, may be offered in different forms:

· whole unfractionated serum

· IgG fraction (7S)

· isolated monoclonal antibodies (MAb)

· immuno­affinity isolated antibodies (PAb)
