| -performed via HCR-FISH using 3 probe sets targeting the RA isoform transcript |
| -There is no entry for this gene on BDGP, and modENCODE RNAseq data on FlyBase indicates that it is not expressed in the embryo. However, we observed obvious patterns during embryogenesis. Additionally, FlyBase does not have any in-depth characterizations of this gene. |
| -Osi21 does not overlap with any other genes, ruling out the possibility of the targeting of alternative transcripts. BLAST also confirms the specificity of our probes to Osi21. Additionally, no other genes for which probes were designed for on this plate show patterns such as those observed here, ruling out the possibility of cross-contamination during probe preparation. |
| -This may be a result of Osi21's poor characterization or incorrect RNAseq data |
