Conventional PCR primers are indicated by an asterisk (*). Nested PCR with two pairs of primers (outer and inner) was used for single-cell RT–PCR experiments. Information of some primer sequences for TRP channels was obtained from a previous study [50] and PrimerBank [51], and the primers are indicated with a dagger (†) and a double dagger (‡), respectively. PrimerBank IDs are presented with the cited primer pairs. To access the data, click or select the words “Appendix 1.”
