Assuming that both are heat inactivated and sterile filtered, is there a difference between normal goat serum and donor goat serum. I can't seem to find any major difference between Is their an advantage of one over the other if the application is for immunohistochemistry/immunofluorescence.
Thanks
Hi Neil. Normal goat serum and donor goat serum essentially refer to the same biological product, which is serum obtained from the blood of healthy goats. However, it's always good practice to check the datasheet or specification provided by the supplier to confirm any subtle differences that may exist between the products.
It is the same ideally. Companies to make fool of researchers and to avoid to interfere the copyright of other company name, they put the other name. It is only copying the copyright of other company.
For example: here is definition of Donor Goat serum according to one company:\
Donor Goat Serum Summary
Donor Goat Serum (DGS) is used as a blocking agent in immunochemistry applications, and in other specialized cell culture applications.
Why Use Donor Goat Serum?
Donor Goat Serum is collected from selected donor herds that receive regular veterinary inspection and care and are found free of hoofed animal diseases. Serum products should be stored and handled correctly to assure long-term stability and to preserve growth performance consistency throughout its shelf-life. In addition, heat inactivation of serum is frequently desired to inactivate complement within the serum. Below are protocol links for serum storage/handling and heat inactivation.
On other side: Normal goat serum is the same. Does not mean that company spit in this serum and label it.
It means it is way of bullshitting with scientists.
Of course, NGS is also collected from disease free goats
