Seplite

SEPLIFE® Chromatography medias Chromatography separation medias are based on Agarose & Dextran& polymer matrix. Chromatography is a technique that is used for separation of mixtures.The components of the mixture to be separated flow through the stationary phase material at different rates, which creates waves or bands. Originally, those bands were detected by visible color differences. Detection methods are now based on the chemical and physical properties of the molecules being separated, including, but not limited to color, UV absorbance, size, charge, and hydrophobicity. Sunresin offers a wide range of Seplife ® chromatography media  that provides unique selectivity, high efficiency, and scalable operations from capture to polish applications. Sunresin has exploited three matrixes, Agarose and Dextran-based chromatography medias could replace the GE life science( Sepharose and Sephadex series )completely but in a saving costs, while polymer-based chromatography

SEPLITE ® Chelating Resin SEPLITE® chelating resin  is ion exchange chelating resins for metals removal, recovery and enrichment. Chelating resins are a class of chelating ion exchange resin   with reactive functional groups that chelate to metal ions. They have the same bead form and polymer matrix as usual ion exchange resin, and the variation in chelating resins arises from the nature of chelating agents linked into a polymer backbone. SEPLITE ® Chelating resins contain a wide range of special functional groups that gives them superior selectivity for specific target metals, Such as SEPLITE®LSC710, which is the iminodiacetic acid bonded in a styrene-divinylbenzene matrix. Other functional groups bound to chelating resins are aminophosphonic acid, thiourea, 2-picolylamine and so on. Chelating resins of ion learning exchange   are almost always used to bind cations, which are found in a big range of metals removal, recovery and enrichment in a dilute solution. Chela

Another Name: AM resin The Aminomethyl resin  is one of the most widely used functionalized supports for solid-phase synthesis. Many supports can be made by acylating this resin with carboxylic acid-containing linkers using  standard methods of amide bond formation to furnish supports for SPOS. It is also used as a scavenger resin in solution phase synthesis to remove excess acids, alkylating agents and other electrophiles.

2CTC Resin An extremely acid-labile resin  of ion learning exchange  for preparing peptides and partially protected peptide fragments by the Fmoc strategy. This resin is ideal for use in the preparation of peptides containing C-terminal Cys, His, Met, Tyr and Pro residues. Cleavage for protected peptides from this matrix can be effected by treatment with AcOH/TFE/DCM,0.5% TFA or HFIP. Fully deprotected peptides can also be obtained by cleaving with 95% TFA in the usual manner.

When the operation is carried out for a certain period of time, the resin bed will be divided into a saturated resin zone, a mass transfer zone, and a fresh resin zone. As the run time increases, the mass transfer zone gradually decreases until the bottom of the bed is penetrated by the mass transfer zone and the entire resin layer fails. For one application, the  fixed bed system  is usually operated in single column or two columns in series, plus a column for regeneration.

The whole section of resin in the  original fixed bed  is divided into several sections, and different sections of resin play different roles at the same time, so that the various sections of the original fixed bed adsorption, washing, desorption, regeneration and the like are integrated into one system equipment. By using the part of the resin that was originally idle, this greatly improves the resin utilization rate while reducing the chemical consumption through an effective connection operation mode. Advantage:  Integrate all steps, continuous operation, and strong system matching. Compact structure, less piping and less floor space. High resin utilization. High product yield, concentration and purity, and good stability. Less water and chemical reagents. Good operational flexibility according to the change of production load. Adjust valve switching speed or adjust flow rate. Three wastes are rarely emitted, reducing environmental pressure. Typical Application:

The biotechnology industry is the most promising industry in the 21st century. With the development of biotechnology, the industrialization of biological products has increasingly become a concern of people. In the production process of biological products, the separation and purification of products, especially the separation and purification of active macromolecules, has become a recognized key link in the downstream technology of bioengineering, which determines the prospect of industrialization of biological products. Chromatographic separation technology  is a kind of separation method widely used in the separation and purification of complex mixtures. Various chromatographic methods involve common basic features: there is a stationary phase and a mobile phase, when the biological mixed stock solution (mobile phase) passes When a tube or column (stationary phase) is filled with a bead or matrix material, the physicochemical properties (such as attractiveness, solubility, molecular

The process of separation and purification of biomacromolecules by ion exchange chromatography is mainly carried out by using the dissociation properties of various molecules, the net charge of ions, and the electrical difference of surface charge distribution. It has become one of the most frequently used purification techniques for the separation and purification of biochemicals, proteins, peptides and other substances. In the separation and purification, the column is required to have high loading capacity, easy operation and long service life. The separation medium is the most important factor. Therefore, the selection of the separation medium is particularly important. 1.1 Selection of varieties: A suitable  ion exchange chromatography medium  should be selected according to the type of charge, the size of the molecule, the physicochemical properties and the microenvironment of the target product to be separated and purified. For inorganic small molecules, the choice of separation
