4-(2',4'-Dimethoxyphenyl-Fmoc-aminomethyl)-phenoxyacetamido-AM resin

This rink amide am resin attached to aminomethyl resin, and is an ideal tool for the Fmoc SPPS of peptide amides. Cleavage from this resin can be effected by single step treatment with 95% TFA, providing peptide amides in high yields and purities.

SEPLITE ® Strong Acid Cation Exchange Resin

The Strong Acid Cation Exchange Resin( SAC resin) is the type of ion exchange resin with functional group of sulfonic acid

The strongly acidic ion exchange resin has two types, the gel and the macroporous type. The macroporous strong acid cation exchange resin shows an excellent dynamic characteristics. The gel type has excellent properties for industrial water softening and demineralization application. It has standard crosslinkage, which is usually used in mixed bed; the higher crosslinkage resin shows a longer operating life, and used in regenerable mixed bed.

The Strong Acid Cation Exchange Resin shows an excellent physical and chemical stability, which operates at any pH(0-14), and are relatively stable to temperture, even in high temperatures of 100-120℃.

The Strong Acid Cation Exchange Resin is applied in a wide variety of fields including water purification, water softening, waste water treatment, purification of pharmaceuticals and food, chemistry,and catalysis.

Separation Technique Based on Ion Exchange & Adsorption

Stevioside extraction and purification is mainly extracted from the roots and leaves of stevia leaves, with the highest content of stevioside in leaves. Its sweet taste mainly consists of stevioside A, B, C, D, E. Stevioside can be extracted with water, and after clarification and crystallization, extracts of different purities can be obtained.

Stevioside is 250-450 times sweeter than sucrose, but because of the presence of stevioside A, it has a distinct bitter taste and astringency.

Our technology in stevioside extraction is based on the principle of ion exchange and adsorption, using a series supporting separation system to achieve extraction, decolorization, demineralization, purification and other important steps. Our technology has achieved great success in China.

Sunresin has conducted in-depth research in the field of stevia refining. Sunresin once hosted the China Stevia Industry Technical Exchange Conference and achieved great success. China's stevia manufacturers like to work with Sunresin and continue to accelerate their industry upgrades through Sunresin's technology.

Peptide Synthesis Resins

Since Solid Phase Peptide Synthesis(we can also call it spps resins) was first proposed by Robert Bruce Merrifield, the method of synthetic peptides became more popular than liquid phase peptide synthesis because of high efficiency. This method could assemble a peptide chain rapidly through successive reactions of amino acid derivatives on an insoluble support.

The original peptide antibiotics are also biosynthesized and extracted from the culture of polymyxa or aeruginosa. Another synthetic method of peptides is chemical synthesis, which is divided into liquid phase chemical synthesis and solid phase chemical synthesis. The liquid phase method is mainly used for the synthesis of short peptides. The solid phase synthesis method can be used to prepare long-chain peptides, cyclic peptides, and complex. Peptide. The solid phase method is divided into a Boc method and an Fmoc method. It requires the solid phase synthesis of the carrier to achieve the growth of the peptide chain by means of stepwise amino acid condensation. The advantages of solid phase synthesis are ease of purification, shortening of the synthesis cycle, and ease of automation.

Solid phase peptide synthesis(SPPS) support consists of small, polymeric resin beads functionalized with reactive group such as amine or hydroxyl groups, which link to systhesis peptide chain step by step.

Solid phase peptide synthesis(SPPS) resins is insoluble in all common solvents but swells well in most organic solvents. Better swelling degree is benefit for the reaction yields, but for short peptide easy to synthesis, lower swelling degree will be suitable and it will be good at saving solvent.

Solid phase peptide synthesis Resins are rich in variety, complete in specifications and stable in performance.

Typical Applications

Solid phase synthesis of Bivalirudin

Solid phase synthesis of Eptifibatide

Solid phase synthesis of Exenatide

Solid phase synthesis of Liraglutide
