AliCE® Cell-Free Protein Synthesis Kit Quick Start Guide

Important – Before you begin

  • RNase contamination leads to lower or no protein yields. Only use RNase-free filter tips and wear gloves at all times!
  • The ALiCE® CFPE Kit requires oxygen during the whole reaction time for a successful reaction. Do not seal reaction vessels!

Step 1 – Choose reaction vessel

ALiCE® Tubes or 96 half-well plate with lid

Step 2 – Prepare DNA

Thaw DNA template at room temperature, mix briefly and do not heat-treat.

Positive control plasmids pALiCE01 and pALiCE02 are supplied ready-to-use at 250 ng/µL. See instruction manual for additional information on template preparation.

Step 3 – Thaw ALiCE® reaction mix

Thaw the ALiCE® reaction mix in a water bath at room temperature (20 - 25 °C). Do not vortex ALiCE® Reaction mix! Place on ice directly after thawing. Start reactions within 30 min after thawing.

Freeze remaining lysate at -80 °C. Do not use liquid nitrogen. Avoid more than one freeze-thaw cycle.

Step 4 – Reaction assembly and reaction

Note: When using pALiCE plasmids with different inserts, dilute or concentrate to the same final molarity of 5 nM. DNA concentration may significantly affect protein yield.

use plates from Greiner Bio-One, Art. No. 675086

* For best results, use plates from Greiner Bio-One, Art. No. 675086

Step 5 – Reaction parameters

Due to the long incubation time, evaporation may occur. Please refill the reaction vessel with RNase-free water to 50 µL after the reaction is completed.

Usage Notes

  • Template DNA is a common source of RNase contamination. Purification of DNA with a procedure based on anion exchange chromatography is therefore highly recommended. Alternatively, the template DNA can be purified by phenol-chloroform extraction prior to use with the ALiCE® kit. Also, RNase inhibitor can be added before the reaction.
  • When using other reaction conditions or other volumes than stated above or hindering the oxygen transfer by sealing the plates, protein yields will be diminished.
  • For additional information on plasmid preparation, protein purification (SDS PAGE) and micro- some targeting, please refer to the instruction manual.
