SDS USER MANUAL

CellMosaic® has designed this personalized immobilization kit to work with small molecules containing one carboxylic acid functional group. This kit is custom made to order. Some of the small molecules may contain other functional groups that can interfere with the reaction such as amine. We recommend the customer to email your information of your small molecule before placing this order.  

The user supplies the small molecule acid. Using the kit components, the user converts the carboxylic acid to an activated sulfo N-hydroxysuccinimide ester (NHS ester), followed by reaction with amine-modified agarose beads. Scale of the reaction: 5 mL


Key Features of this SepSphere™ Immobilization Kit:

  • Offers a simple and easy way to label small molecules with carboxylic acid
  • Fast and easy preparation: 3 h preparation and less than 30 minutes hands-on time
  • Stable linkage (no leakage of the small molecules from the resin under acid or base condition)
  • All reagents and supplies include for preparation
  • Use agarose beads with optimized amount of amine functional groups for loading to preserve the nature of the agarose beads

Typical Kit Performance Data (LC Analysis, CellMosaic)

Small molecule information: Fmoc-Gly-OH

Figure 1: C18 HPLC/UV analysis of Fmoc-Gly-OH before (sample C1) and after immobilization (sample C3) (detected at 254 nm). Left inset: UV spectrum of Fmoc-Gly-OH peak 8.63 min. Right insert: expansion of the HPLC profile from 8.0 to 9.6 min.

Experiment for analyzing the Fmoc group loaded onto the resin: After immobilization of Fmoc-Gly-OH, ~100 µL of beads were removed and added into 200 µL of 20% piperidine in NMP. After mixing for 15 minutes, 5 µL were removed for HPLC analysis. The HPLC profile is identical to the profile obtained from Fmoc-Gly-OH deprotection, confirming that Fmoc-Gly-OH is loaded onto the resin.
