This unit describes the use of the polymerase chain reaction (PCR) to characterize rearranged murine T cell receptor (TCR) transcripts present in primary lymphoid tissues, peripheral lymphoid tissues, and extra-lymphoid sites of inflammation, and to quantify them either relatively or absolutely. This methodology has been used extensively to characterize TCR variability in murine thymus and liver in T cell clones, and in extralymphoid tissues where the absolute number of T cells is limited. A procedure for cloning and sequencing PCR-amplified cDNA transcripts is provided to examine the junctional diversity of expressed genes. Also included is a method for reverse transcription of RNA into cDNA that is optimal for analysis of tissue samples where the number of T cells is limited. The detailed protocols are followed by a commentary that discusses strategies and artifacts as well as providing troubleshooting suggestions for PCR amplification and TCR analysis.
