Hi everybody,
This is really a curiosity more than technical problem. What's the
reason for using fetal calf serum to make cell cultures??. Why not, for
example, newborn calf is usually cheaper?. All the companies I called
said that such serum came from animals less than 10-12 days old, so if
the animal is healthy what's the reason for not using that thing?
