Receiving and Quarantine -
Timelines – Quarantine Rederivation Program
Donor Mice Required to Commence Rederivation:
|
4 Males that are 8-15 weeks of age |
|
8 Females that are 3-4 weeks of age |
|
Please note that additional donors may be required if no litters are successfully rederived or if the donor animals provided are too old for breeding
|
The Time Required to Build a Colony and Distribute Mice Depends on:
|
How rapidly the strain is transferred to NCI-Frederick |
|
The number of mice transferred by the donating investigator |
|
The age of the mice transferred |
|
Strain Fecundity |
|
Whether IVF (in vitro fertilization) is an option for colony expansion |
The Following Chart Was Constructed Using these Assumptions:
|
Target Colony Size = 15 breeder pairs |
|
Generation Time = 12 weeks |
|
Average Litter Size = 6 |
|
Male and female produced equally |
|
Both males and females may be used and distributed as breeders |
|
Adequate space in Receiving and Quarantine (R&Q) for large-scale IVF |
