Embodiment 1

[0011] Present embodiment is to the labeling method of neonatal suckling mouse:

[0012] The rat fetuses in the same cage were divided into male fetuses and female fetuses according to their gender. Black tattoo ink was used for male fetuses, and cyan tattoo ink was used for female fetuses.

[0013] Wipe the target injection site of the rat fetus with alcohol before injection.

[0014] Using a needle no larger than 25G, inject black tattoo ink into the target injection site of male fetuses by subcutaneous injection, and inject cyan tattoo ink into the target injection site of female fetuses to distinguish between male fetuses and female fetuses.

[0015] The amount of tattoo ink injected should only be visible to the naked eye under the fetal skin.

[0016] The injection site can choose more than one paw among the four paws of the rat fetus.
