Although presently DMTMM is quite expensive, we estimated a price of 4.0–4.5 €/kg to produce DMTMM. This figure has been calculated, based on the synthetic procedure reported by M. Saijo ( Saijo and Hirano, 2002 ), summing to the bill of materials (3.0–3.3 €/kg) production costs of about 1.0–1.2 €/kg (25% of the material costs).

A volume of 875 μl of each polysaccharide was treated with 70 μl of a 200 mg/ml solution of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) (Sigma-Aldrich, MO, USA) in sterile water. The polysaccharide/DMTMM mixture was incubated in the dark, on a rotator, for 1 h at room temperature (RT).

In comparison, for the reaction at 56 °C M56111 performed without any further addition of DMTMM and amines during the whole duration of the reaction, a stable DS of around 20% for 4 days was observed, suggesting that the DMTMM is a limiting reagent in our reaction likely due to its inactivation. Therefore, the higher temperature has a double 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) to EDC/NHS activation chemistry for HA ligation using an array of substrates including small, large and functional molecules.

11 Feb 2021 DMTMM (Sigma-Aldrich) was prepared at a 120 mg/mL concentration in 1× PBS pH 7.

Although presently DMTMM is quite expensive, we estimated a price of 4.0–4.5 €/kg to produce DMTMM. This figure has been calculated, based on the synthetic procedure reported by M. Saijo ( Saijo and Hirano, 2002 ), summing to the bill of materials (3.0–3.3 €/kg) production costs of about 1.0–1.2 €/kg (25% of the material costs). DMTMM-mediated amidation of HA proceeds through an aromatic substitution forming an intermediate s-triazine ester of HA reactive towards amines (compound 1, Scheme 1).

Using degassed pH 6.5 2-(N-morpholino)ethanesulfonic acid (MES)-buffered saline (MBS) with 10 mM ethylenediaminetetraacetic (EDTA) acid as a buffer, PGA stocks were prepared at 13.2 mg/mL (100 mM glutamate monomer). 4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)–4-methylmorpholinium tetrafluoroborate (DMTMM; Sigma-Aldrich Co., St Louis, MO, USA) was added at 150 mol% relative to glutamate monomer Methods for making and using a programmable bead composition that in some embodiments includes a magnetic bead coupled to an antibody with DMTMM and an antigen coupled to the antibody, with the antigen having been expressed from a human cell lysate (FIG. 1). DMTMM has many advantages, including easy by-product removal, 99 good stability in water, and high reactivity. In addition, DMTMM-activated carboxylic acids 100 show poor reactivity with alcohols.
