Product Name Catalog No. Unit Qty Storage
Premium PLUS Expression Kit for MS EDX-PLUS-MS 1 set 16 reactions -80
This product is shipped on dry ice: Store at -80 upon arrival.

The Premium PLUS Expression Kit for MS provides premixed reagents to perform cell-free protein expression reactions for preparation of [13C, 15N]-L-Lys and [13C, 15N]-L-Arg labeled proteins. Each kit contains the reagents to perform 16 SP6-driven mRNA expression and wheat germ protein labeling reactions.

Intended Use

Preparation of [13C, 15N]-L-Lys and [13C, 15N]-L-Arg labeled proteins for use in protein mass spectrometry experiments. Heavy isotope labeled proteins may be used as controls in sample preparation, for determining digestion efficiency, or as standards for protein quantification.

Key Features:
Labeled proteins are obtained in a fast and convenient three-step process:

Protein Expression made easy: Obtain Template > Express Labeled Protein > Confirm Expression!

Reaction Steps
  1. Transcription using either plasmid DNA template or linear DNA template, incubation at 37 for 1 hour (plasmid DNA) or 4 hours (linear DNA).
  2. Translation of target protein by bilayer reaction, incubation at 15 for 20 hours (plasmid DNA) or 24 hours (linear DNA).

Apparatus required for reaction

Incubator (Transcription at 37 , translation at 15 )
