Controlled Pore Glass (CPG) has been widely used as a solid support for oligo synthesis for several decades. LGC Biosearch Technologies has perfected CPG manufacture for maximum oligo purity and yield. Our advanced CPG production techniques improve control of particle size and shape, pore size, pore volume, and specific surface area. These physical parameters influence solution exchange behaviour, ligand loading and distribution, and reaction kinetics to increase the efficiency, purity, and reproducibility of syntheses.

LGC Biosearch Technologies has developed proprietary chemical attachment procedures to further optimise ligand distributions, providing increased accessibility to synthesis reagents and washing solutions and facilitating even better oligo yields and purities. Furthermore, process refinements and proprietary assays have been developed to minimise the troublesome “N-1” impurity levels in an oligo synthesis.

LGC Biosearch Technologies Prime CPG is considered to be the gold-standard solid support used in all sectors of the market. Our collaborative process has resulted in solid supports that are optimised for the synthesis of the latest therapeutic oligo classes including LNA, delivery enhancing lipid ligands, siRNA and Spiegelmers. LGC Biosearch Technologies CPG RNA solid supports are available in a variety of pore sizes and functionalised nucleoside loadings. Which pore size and loading required is dependent on the length, complexity and application of the oligo. In general, large scale oligo synthesis for therapeutic applications requires high loaded 500-600 Å and small to medium scale synthesis for diagnostic or research use require higher pores sizes.

Key features:

  • Longchain alkylamino linker
  • Standard bulk density 0.250.33 g/cc
  • Prime CPG suitable for customers with large scale or therapeutic development requirements
