Expression patterns of OBP genes by RT-PCR in adult tissues.

Specific primers of forty-seven putative OBP genes were used in non quantitative RT-PCR experiments using thirty-four cycles of amplification. Yes: a PCR product of the expected size has been detected in a given tissue; No: absence of band. The same primer pairs have been used for CquiOBP35 and CquiOBP39, and for CquiOBP36 and CquiOBP38. Expression patterns are as follows. Olfactory-specific: detected only in antennae, palps or proboscis; non olfactory-specific: detected in antennae, palps or proboscis as well as in legs and/or bodies; ubiquitous: detected in every tissue; not detected. Olfactory-specific OBPs are in bold.
