Probe synthesis.

Protein synthesis is a biological process that allows individual cells to build specific proteins. Both DNA (deoxyribonucleic acid)and RNA (ribonucleic acids) are involved in the process, which is initiated in the cell’s nucleus.RNA probes are commonly synthesized with the RNA polymerases from bacteriophages SP6, T7, or T3 by in vitro transcription of DNA, which is cloned into appropriate transcription vectors like the pSPT-vector family containing highly specific SP6-, T7-, or T3-specific promoters in front of a multiple cloning site (Melton et al., 1984; Morris et al., 1986; Krieg and Melton, 1987).
