| Title |
500microg/L_Zn_Exposed_rep4B |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
whole organism, exposed 24-h to 500 microg/L Zn
|
| Organism |
Daphnia magna |
| Characteristics |
Daphnia magna: Aquatic Research Organisms
Age: 15-18 days
|
| Biomaterial provider |
Vulpe Lab, UC Berkeley
|
| Treatment protocol |
24-h waterbourne exposure to 500 microg/L Zinc Chloride
|
| Growth protocol |
Genetically homogeneous Daphnia magna, purchased from Aquatic Research Organisms (Hampton, NH), were cultured in COMBO modified for water hardness (Kilham et al. 1998) and kept at 23.50 C in a Percival environmental chamber with a 16-hour light/ 8 hour dark cycle. The D. magna were maintained on a diet of YCT and Selenastrum capricornatum (Aquatic Research Organisms, Hampton, NH). Stock culture medium was renewed, cultures were fed, and neonates were separated from adults three times weekly.
