Insulin and insulin-like growth factor 1 (IGF1) are two closely related proteins and share similarities in both primary and tertiary structure. The homology is paralleled by similarities in the structures of their receptors, the insulin receptor (InsR) and the IGF1 receptor (IGF1R), which belong to the same family of receptor tyrosine kinases. 

When studying the InsR and IGF1R is it therefore important to use specific antibodies that does not cross-react with both receptors. NNC0276-3000 is a highly specific InsR monoclonal antibody that lack cross-reactivity to the IGF1R. NNC0276-3000 is a human IgG1 monoclonal antibody directed against alfa-subunit of insulin receptor.

Also, unlike earlier monoclonal antibodies reported in the literature, this antibody shows cross-species reactivity to the extracellular domains of mouse, rat, pig, and human receptors, indicating that it binds conserved epitopes. Furthermore, the antibodies work well in several different assay formats and therefore provide a new tool to study InsR and IGF1R biology with translation across several species and experimental model systems.

Calculated and experimental properties of NNC0276-3000 and the isotype control (NNC9416-0015).

The antibodies are of very high purity and have a minimal amount of aggregates as determined by SEC-HPLC. The isotype control (NNC9416-0015) is anti-trinitrophenol (aTNP), the isotype control standard used in most in vitro and i n vivo applications since the antigen is not considered present in mammals.

The isotype control to NNC0276-3000 is NNC9416-0015. Please indicate in the 'Purpose' field when you order NNC0276-3000 if you would like to have NNC9416-0015 included in your shipment.

We recommend to store the antibodies at minus 80C. Four weeks stability at 4C have been confirmed.
