GPC

GPC- PEP  

GPC PEPTIDE is a glycerol bonded size exclusion support on a 5µ , 50Å spherical silica which can resolve small peptides (MW 0.8-30 kD). This support can resolve peptides which have at least a two-fold MW difference. Mobile phase optimization may be necessary due to the high variability in solubility, charge, and hydrophobicity of peptides. The exclusion limit for GPC Peptide makes it an effective "desalting column" for processing protein samples.

 

 

GPC-100  

GPC-100 is a glycerol bonded size exclusion support on 5µ , 100Å spherical silica designed for the rapid analysis of proteins, carbohydrates, nucleic acids, and other water-soluble polymers. This support is appropriate for globular molecules with MW ranges from 5-160 kD and linear molecules with MW ranges from .5-25 kD.

 

 

GPC-300  

GPC-300 is a glycerol bonded size exclusion support on 5µ , 300Å spherical silica designed for the rapid analysis of proteins, carbohydrates, nucleic acids, and other water-soluble polymers. This support is appropriate for globular molecules with MW ranges from 10-1000 kD and linear molecules with MW ranges from 2-100 kD.

 

 

GPC-500

GPC-500 is a glycerol bonded size exclusion support on 7 µ , 500Å spherical silica designed for the rapid analysis of proteins, carbohydrates, nucleic acids, and other water-soluble polymers. This support is appropriate for globular molecules with MW ranges from 40-2000 kD and linear molecules with MW ranges from 10-350 kD.

 

 

GPC-1000  

GPC-1000 is a glycerol bonded size exclusion support on a 7 µ , 1000Å spherical silica designed to effectively analyze polymers by size. This support has minimal interaction with anionic and neutral water-soluble polymers and is most frequently used with linear molecules possessing MW ranges from 40-1000 kD. It also allows for the separation of globular molecules such as protein multimers with MW ranges from 400-10,000 kD.

 

 

GPC-Linear

GPC Linear is a glycerol bonded size exclusion support on a 7 µ mixed pore distribution (100/1000 Å) spherical silica allowing analysis of samples with a broad range of MW's. This support has minimal interaction with anionic and neutral water-soluble polymers and denatured protein possessing MW ranges from 1-1000kDa.

 

 

GPC-4000  

GPC-4000 is a glycerol bonded size exclusion support on a 10 µ , 4000Å spherical silica designed to effectively analyze lineaar polymers by size. This support has minimal interaction with anionic and neutral water-soluble polymers and is most frequently used with samples containing linear molecules having MW >10,000 kD.

CATSEC

CATSEC-100  

CATSEC-100 columns is unique to Eprogen designed specifically for analysis of cationic polymers.  CATSEC-100 columns have a proprietary polymeric bonding chemistry on a 100Å, 5µ spherical silica support designed for separating linear molecules with molecular weight ranges of .5-25 kDa.  The polymerized coating enables polymers such as polyvinylpyridines to elute according to size and without adsorption.  Mobile phases are generally acidic and contain 0.1-0.2M salt to minimize adsorption and ion-exclusion.

 

 

CATSEC-300  

CATSEC-300 is unique to Eprogen designed specifically for analysis of cationic polymers.  CATSEC-300 columns have a proprietary polymeric bonding chemistry on a 300Å, 5µ spherical silica support designed for separating linear molecules with with a molecular weight range of 2-100 kDa. The polymerized coating enables polymers such as polyvinylpyridines to elute according to size and without adsorption. Mobile phases are generally acidic and contain 0.1-0.2M salt to minimize adsorption and ion-exclusion.
