In the following labeling methods, the label is attached to one of the 4 nucleotide triphosphates and then incorporated into the probe. • PCR labeling. A Polymerase chain reaction (PCR) is a powerful procedure for making gene probes because it. is possible to amplify and label, at the same time, Alternative probes may be prepared where the label occurs on one of the termini of the DNA, These methods are described further in the ABI manual. PROBE® labeling reagents or the FastTag® Nucleic. Acid Labeling System. Either labeling method re- sults in the covalent coupling of the label to the. P. Singleton, DNA Methods in Clinical Microbiology In one approach the probe's label is an enzyme which reveals the presence of the bound probe by. In addition, the bioconjugation methods used for nucleic acid probe TdT is often used to label DNA probes for RACE (Rapid Amplification of cDNA Ends), Choice of label and labeling method A myriad of labels is available, many of which may have advantages for particular applications.When a label is attached to such a hybridization probe it can ling of DNA probes in a one-step procedure (Fig. 2).
