For DMTMM-coupled reactions, 450 pmoles of DNA was combined with peptide (270 nmoles, 600 eq.) and DMTMM (4.5 μmoles, 10,000 eq.). EDC-based coupling reactions followed the same procedure as above using EDC (4.5 μmoles, 10,000 eq) and N-hydroxy

2021-01-01 · Tyr conjugation to HA was catalyzed by adding 5 mmol 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) (TCI Europe N.V.) coupling agent followed by 5 mmol Tyr (Sigma-Aldrich, St. Louis, MO), which was slowly added to the reaction. The reaction occurred at 37 °C under continuous stirring for 24 h.

Methods2.2.1. 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).

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). 4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride hydrate is used as a pharmaceutical intermediate. It is used as a reagent for activating carboxylic acids in solution and solid phase peptide synthesis. obtained from Sigma-Aldrich were kept in the dark.

Moreover, CMC fulfils minimum requirements necessary for the use of DMTMM containing both carboxylic and hydroxyl groups on the polymeric chain. 2. Material and methods2.1. Materials. CMC with carboxylation degree C = 0.7, average molecular weight 90,000 Da, glycerol and DMTMM were purchased by Sigma-Aldrich Co. (St. Louis, MO). 2.2. Methods2.2.1.

Bead-based serology Suspension arrays were performed with a flow cytometry-based Luminex 200, using LPS-conjugated paramagnetic beads to probe for antibodies in agglutination serum (rabbit) or pig serum; sera were diluted respectively 1:25 triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) (Sigma-Al-drich, MO, USA) in sterile water. The polysaccharide/DMTMM mixture wasincubatedinthedark,onarotator,for1hatroomtemperature(RT).

Analysis of Reagent Purity: generally used as received. 2018-07-27 · The five LPSs were coupled to five distinct bead sets, using 2.5 × 10 6 carboxylated paramagnetic beads per bead set in separate coupling reactions (bead addresses 28, 43, 51, 57, or 72; MagPlex Microspheres, Luminex, ‘s-Hertogenbosch, the Netherlands) with the triazine DMTMM (Sigma-Aldrich) as described . 2019-05-20 · 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). 4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride hydrate is used as a pharmaceutical intermediate. It is used as a reagent for activating carboxylic acids in solution and solid phase peptide synthesis.

To remove unreacted DMTMM and AEM, the 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 … 2019-08-26 immobilized on DEAE Sepharose media (DFF-100, Sigma). Reactions with water-soluble coupling reagents EDC (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochlo-ride) and DMTMM (4-(4,6-dimethoxy[1,3,5]triazin-2-yl)-4-methyl-morpholinium chloride) were completed using both Sepharose media and in solution-phase.
