Periodic table resin Lanthanides The lanthanide series of chemical elements comprises the fifteen metallic chemical elements withatomic numbers 57 through 71, from lanthanum through lutetium . These fifteen lanthanide elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. Actinides The actinide series encompasses the 15 …
PAM Resin
4-Hydroxymethyl-phenylacetamidomethyl resin PAM resin has become the most widely used resin in Boc chemistry peptide synthesis. It has greater acid stability than Merrifield resin, making it suitable for synthesizing medium and large peptides, such as DNA binding polyamines, human matrix Gla protein(MGP), Kappa-casein. The first carboxylic acid is attached to PAM resin using an activating agent …
Weak Base Anion Exchange Resin (WBA)
SEPLITE ® Weak Base Anion Resin The Weak Base Anion Exchange Resin with primary, secondary, tertiary amine or mixed amine group as active functional groups show different strengths of alkalinity. Most weak Base Anion Exchange Resins with mixed amine group equiped a extremely high operating capacity with the ability to remove both strong and weak …
Fmoc/t-Bu Solid Phase Synthesis
The Fmoc method is a new method for solid phase synthesis of peptides developed by Carpino and Hart based on the Boc method. The fundamental difference between the Fmoc ltd /t-Bu(9-fluorenylmethoxycarbonyl/tert-butoxy) strategy and the Boc/Bzl strategy is the use of alkali-removable Fmoc is a protecting group for α-amino group, the side chain is protected by t-Bu which …
Strong Base Anion Exchange Resin (SBA)
SEPLITE ® Strong Base Anion Resin The Strong Base Anion Exchange Resin( SBA resin)is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH. In chemical structure, there are two types of strong base anion exchange resin with different alkalinity strengths, Type Ⅰ …
Strong Acid Cation Exchange Resin (SAC）
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 …
Stevioside Extraction And Purification
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 …
Solid Phase Peptide Synthesis
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 …
Sieber Resin
9-Fmoc-Aminoxanthen-3-yloxy-polystyrene resin A hyper acid-labile linker or the Fmoc SPPS of protected amides via mild 1% TFA cleavage. The sieber amide resin can be readily reductively alkylated to provide a support suited to the synthesis of secondary carboxamides. This resin has also been employed to produce protected peptide fragments in wich the C-terminal carboxylic acid group …
Rink Amide-MBHA Resin
4-(2',4'-Dimethoxyphenyl-Fmoc-aminomethyl)-phenoxyacetamido-MBHA resin This rink amide mbha resin comprises the modified Rink amide linker attached to MBHA resin, and is an ideal tool for the Fmoc SPPS of peptide amides. Cleavage fro this mbha resin can be effected by single step treatment with 95% TFA, providing peptide amides in high yields and purities.
