If you have hopes for cysteine residues in reasonable proximity, then bis-iodoacetamide (with a suitable spacer, commercially available is the ethylenediamine spacer). Any reasonable chemist can make you other spacer lengths to order.
Homobifunctional PEG with maleimide, N-hydroxy succinimide esters, etc might work also. Homobifunctional PEG with amines on ends can be used with a water soluble coupler e.g. EDC NBT mix. Notably if you are lucky just treating protein as a dimer with EDC NBT mix can promote clinking. Bis aldehydes are an old standby but they are usually quite harsh. Feel free to write directly for/with additional details. Artem On Mon, Oct 19, 2020, 3:18 AM Chiara Bruckmann <bruckmannchi...@gmail.com> wrote: > Dear all, > > Sorry for the off-topic question.
