Table 2.
Specific primers for the human P2X1, P2Y1, P2Y2, P2Y4 and P2Y6 receptors were constructed based on published nucleotide sequences [21-25], as follows.
| Primer | Nucleotide sequence | Product length × (base pairs) |
| P2X1 forward | 5'-GTTTGGGATTCGCTTTGA-3' | |
| P2X1 reverse | 5'-GGCTGAGAGGGTAGGAGAC-3' | 383 |
| P2Y1 forward | 5'-ACGGGCTTCCAGTTTTAC-3' | |
| P2Y1 reverse | 5'-CCAAGGGGACACAGAACA-3' | 550 |
| P2Y2 forward | 5'-CTCTGCTTCCTGCCATTC-3' | |
| P2Y2 reverse | 5'-GCACAAGTCCTGGTCCTCT-3' | 432 |
