Pin-point Protein Labeling   Our technology called "pin-point protein labeling" enables incorporation of an unnatural amino acid at a defined position of protein during E.coli cell-free translation. This incorporation is accomplished by using a synthetic aminoacylated tRNA that carries an unnatural amino acid. This tRNA contains an anticodon which recognizes the UAG stop codon or the CGGG four-base codon.   For more information of our products or services related to this technology, please see under the contents.             [Reagents for Pin-point Protein Labeling]   The following reagents direct the site-directed incorporation of a fluorescence- or biotin-labeled amino acid.
