SILuMab has been validated as an internal standard for quantitation of relevant biotherapeutics in a complex biological matrix by MRM-based LC-MS/MS.

  • SILuMab yielded reproducible, linear curves from 0.1 μg/mL to 1000 μg/mL without enrichment or depletion.
  • Good agreement was observed between multiple peptides derived from the same target.
  • Label incorporation was determined to be >98% by mass spectrometry.
  • Sequence coverage was confirmed by peptide mapping.

Supplied as a lyophilized powder containing phosphate buffered saline

制备说明

SILuMab design is optimized to be used as an internal standard for quantitation of monoclonal antibodies as well as Fc-fusion therapeutics. Because of overlap with the common sequences in the Fc region with candidate antibodies, SILuMab provides univer­sal utility, thus eliminating the need for production of candidate-specific internal standards.
Produced utilizing enriched media containing stable isotope labeled amino acids are 13C<SUB>6</SUB>, 15N<SUB>4</SUB>-labeled Arginine and 13C<SUB>6</SUB>, 15N<SUB>2</SUB>-labeled Lysine.

重悬

SILuMab recovery is maximized when 0.1% formic acid is used for reconstitution of the lyophilized product. Reconstitution with other solvents may reduce recovery. Do not freeze after reconstitution.
Procedure

  • Briefly centrifuge the vial at ~10,000 x g to collect the product at the bottom of the vial.
  • Add 500 μL of purified water containing 0.1% formic acid to the vial.
  • Mix the contents by gently inverting the vial a minimum of 5 times.
  • Allow the vial to stand at room temperature for a minimum of 15 minutes and repeat mixing by inversion.
