Table 1. Efficiency in the generation of transgenic zebrafish. Zebrafish embryos were collected and microinjected with cbp-chrtiGH: pRSGFP (10:1 molar ratio). Survival and GFP fluorescence rates were assayed 24 h post-injection. Transgenic fish were screened for the presence of cbp-chrtiGH sequences by PCR analysis of fin DNA.
