Re[2]: [DIYbio] Substitute for calf serum?

Human serum would work, the problem is cost and amount of material required.  

My idea is to create a profile of FBS, salt, proteins, the the like. Then find the minimum of each protein, salt, and growth factor needed for tissue culturing.   Once identified, create a transmutated organism (yeast, bacteria) to produce said proteins.  Then use that elixir as a replacement for FBS.

Boom, free hamburgers for life!

Thanks James or responding to my question. Your answer made me curious as I find it hard to believe that there could only be one product on the market for anything .  I found what appears to be a bunch of products marketed as substitutes for calf serum with some interesting advantages. Here are a couple. What do you think of these? Are they calf serum alternatives

That is the holy grail of tissue culturing.  If you find a magic elixir with growth hormones, salts, proteins, enzymes, and a desired pH you would be a wealthy person!

Can anyone please tell me if I can use a substitute when a cell culturing protocol calls for calf serum? specifically, a substitute that does not involve cruelty to animals. is it possible to use my own blood serum?
