The present invention relates to the use of a compound containing a moiety of formula (I) as a reagent for linking a compound of formula R1—H which comprises a first functional moiety of formula F1 to a second functional moiety of formula F2
wherein X, X′, Y, R1, F1 and F2 are as defined herein. The present invention also provides related processes and products. The present invention is useful for creating functional conjugate compounds, and specifically conjugates in which at least one of the constituent molecules carries a thiol group.

reagents, particularly in the field of antibody conjugation. Despite this, relatively little work has been performed on the optimisation of their synthesis and subsequent reaction with immunoglobulins. Herein we present a novel synthetic route towards functionalised dibromopyridazinediones, proceeding via an isolatable dibromopyridazinedione-NHS ester. Reaction of this activated intermediate with a variety

The present invention relates to a product comprising a solid substrate and a moiety of formula (I) linked thereto: wherein X, X′ and R are as defined herein. The product is useful for immobilising target molecules such as molecules of biochemical interest to solid substrates for numerous applications, such as affinity chromatography, ELISA, biotechnological assay techniques and solid phase peptide synthesis.
The present invention relates to antibodies and antibody fragments, one or more of whose native inter-chain disulfide bridges have been replaced with a specific bridging moiety. The bridging moiety can be selectively targeted to inter-chain disulfide bonds within the antibody or antibody fragment, enabling the construction of more homogenously modified products such as antibody-drug conjugates.
