CellMosaic® has designed this oligo immobilization kit to work with amine-modified oligos. The user supplies the amine-modified oligos, which are readily available from many commercial oligo suppliers. The kit provides agarose beads derivatized with epoxide functional groups (~2 μmol epoxide per mL of resin). Using the kit components, the customer immobilize the amino containing oligo onto SepSphere™ agarose beads in one step following CellMosaic® standard protocol.

Scale of the reaction: 5 mL

Key Features of this Immobilization Kit:

• Minimum requirement for immobilization set-up
• All reagents, buffers, and plasticwares are included 
• Modestly activated epoxide agarose
• One step immobilization with very mild reaction conditions
• Easy preparation with air push mechanism for washing: less than 1 h hands-on time 
• Stable linkage 

Specification of the Solid Support
