Product Description

UniGel ion exchange media are made of hydrophilic acrylic microspheres with special functionalization on the surface. They provide a loading capacity twice as high as traditional ion exchange media, while resistant to high ionic strength. UniGel series are uniform in particle size, with optimal hydrophilicity, good mechanical strength, and excellent chemical stability; these features make them particularly suitable for capture step (initial separation) in downstream processing.

Nanomicrotech offers UniGel,Uni,UniMSP, and Nano series of monodisperse Ion Exchange Chromatography Media using a unique de novo synthesis technology that is developed in-house. These ion exchange media meet the demands of downstream processing, from capture, intermediate purification, polishing and analysis. UniGel series possess a strong absorption capability toward biomolecules, even under considerably high ionic strength; therefore they are well-suited for the capture and initial purification of proteins. Uni series feature outstanding resolution, high loading capacity, and low non-specific adsorption, making them ideal for intermediate purification of proteins. Nanoseries are smaller in particle size, which is designed specifically for fine separation and analysis of proteins. All these types of media (resins) have the characteristics of high rigidity, good chemical stability, high resolution, low back pressure, and long lifetime, meeting the requirements of bio-analysis, separation, and manufacturing.

Uniseries ion exchange media are made from highly cross-linked acrylic microspheres with a hydrophilic coating; subsequently the desired ion exchange functional groups are later introduced onto the surface. Complete hydrophilic coating greatly reduces the non-specific adsorption between the stationary phase and biomolecules, assuring a better yield. The unique coating and derivatization technology enables Uni series media to have a high dynamic loading capacity of proteins. Uni series media are ideal for efficient separation of biomolecules such as proteins, Nucleic Acids, polypeptides etc.

UniMSP series are multi-modal ion exchange media, with the same base resin and hydrophilic coating as Uni series. The co-existence of bonded ion exchange functional groups and surface hydrophobic groups leads to a mixed interaction of both ion exchange and hydrophilicity. In some cases of purification, UniMSP series could show improved selectivity and resolution, they could also tolerate sample loading at high conductivity.

Features of Nano-Micro Tech Ion Exchange Media

High Uniformity of Particle Size

Nanomicrotech manufactures ion exchange media of highly uniform particle sizes (Fig. 1), with precise pore structures. The product line includes UniGel, Uni , and Uni MSP series media based on polyacrylic matrix, and Nano series of media based on poly(styrene-co-divinylbenzene, PS/DVB). All ion exchange media from Nanomicrotech come with distinct advantages of lot-to-lot reproducibility, easy column packing, etc.

Outstanding Mechanical Strength

Nanomicrotech IEX media are made from highly cross-linked polyacrylic or poly(styrene-co-divinylbenzene, PS/DVB). They have a remarkable advantage of outstanding mechanical strength, when compared with those ion exchange resins based on dextran or agarose. Nanomicrotech IEX media have shown little change in bed volume (Fig. 2), with increasing flow rate or pressure. This feature greatly improves efficiency of downstream processing, and it also addresses the need for a linear scale-up from the lab to manufacturing.

Good Chemical Stability

Nanomicrotech IEX media are made from highly cross-linked polyacrylic or poly(styrene-co-divinylbenzene). They maintain a good stability over a wide range of pH, which gives customer more rooms of operation (parameters/conditions) to achieve process development and optimization.

High Resolution

Nanomicrotech IEX media have shown higher resolution and better recovery than a competitor`s IEX media in the separation of biomolecules, such as proteins, nucleic acids, polypeptides, and polysaccharides (Fig. 4 & 5).
