Cosmo Bio Usa Inc PUREfrex 2.1, 250 µl
PUREfrex can be used to express proteins containing non-natural amino acids by exploiting Protein Express's CloverDirect™ line of tRNA reagents for site-directed protein functionalization. CloverDirect™ UAG or CGGG aminoacyl tRNAs are available charged with different non-natural amino acids that confer a range of functionality, including fluorescent-labeling, biotin-labeling, PEGylation, chemical crosslinking and photo-regulation. Targeting incorporation of specific non-natural amino acids is achieved by designing protein expression templates with UAG and/or CGGG codons at user-defined positions.
