Custom Kit

Overview

PUREfrex® is a reconstituted cell-free protein synthesis system based on the PURE system, which is reconstituted from individually purified factors involved in protein synthesis in E.coli. It has an advantage that the composition of the reagent can be easily customized according to the purpose.

Custom kits are made to order based on PUREfrex® 1.0.

Components of PUREfrex® 1.0

Solution I (Buffer, Salts, Substrates)
Hepes-KOH pH 7.6
Potassium glutamate
Magnesium acetate
Spermidine
Dithiothreitol
10-Formyl-tetrahydrofolate
4 NTPs
20 Amino acids
Creatine phoshate
tRNA mixture
Solution II (Proteins)
20 Aminoacyl-tRNA synthetases (ARS)
Methionyl-tRNA transformylase (MTF)
3 Initiation factors (IF1, IF2, IF3)
3 Elongation factors (EF-Tu, EF-Ts, EF-G)
3 Release factors (RF1, RF2, RF3)
Ribosome recycling factor (RRF)
T7 RNA polymerase
Nucleoside diphosphate kinase (NDK)
Adenylate kinase (ADK, myokinase)
Ceatine kinase (CK)
Pyrophosphatase (PPiase)
Solution III
Ribosome

Examples

(-) RF1 For synthesis of a protein containing a noncanonical amino acid by amber suppression as below.
(-) T7 RNA polymerase For use of other RNA polymerase such as E.coli RNA polymerase.
(-) Specific amino acid(s) and/or
aminoacyl-tRNA synthetase
For synthesis of a protein containing noncanonical amino acid or less than 20 amino acids.
