荷蘭Nordic Immunological Laboratories 
Nordic公司于1934年以生產(chǎn)藥物和化合物成立于荷蘭，逐漸轉向以生產(chǎn)免疫學(xué)和抗血清為主營(yíng)業(yè)務(wù)。公司與荷蘭衛生組織研究院在應用科學(xué)研究合作，研究出一系列獨特的人、小鼠、猴和大鼠免疫球蛋白及其亞基的抗血清。

Nordic was established in 1964 as a firm for manu-facturing and trade of pharma-ceutical 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 immuno-globulin 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 precipi-tation reactions of antisera with the antigen. Although under-estimated nowadays, immuno-electrophoresis, single and double radial immuno-diffusion (Mancini, Ouchterlony) are still valuable techniques. Along with the development of more sensitive techniques Nordic Laboratories produce fluorescent and horse-radish 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 immuno-logical 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.
