Premium PLUS Expression Kit for MS

This starter kit has been designed to be user-friendly even for first-time users.

Our wheat germ cell-free expression system allows you to try stable isotope-labeled proteins easily.


  • Synthesizes stable isotopes 13C and 15N as labeled lysine and arginine residues with over 99% efficiency.(Other amino acids are in unlabeled form).
  • No need to purchase 13C and 15stable isotope labeled amino acids separately.
  • No need to prepare reagents
  • Reagents necessary for each reaction are already pre-packaged in tubes

  • Synthesize proteins with just a few pipetting steps
  • Target proteins can be confirmed through SDS-PAGE/CBB staining

  • Contains enough for 16 reactions on a 226 µl reaction scale

Recommended for:

  • Users who want to confirm the expression of target stable isotope -labeled proteins easily using wheat germ cell-free expression system.
  • Users who require internally standardized stable isotope labeled proteins for use in SRM/MRM analysis of fixed quantities of proteins.



The reagents necessary for each reaction are pre-packaged into tubes, so there is no need to prepare any reagents.

Simply cut off the number of tubes per reaction you need, and you are ready to go.
