I am interested in the Recombinant Human Vitamin D-binding protein(GC) product that you manufacture and would very much appreciate if you would answer all my questions.
1. First and most importantly, is this protein registered with the FDA as a food source, or a pharmaceutical?
2. Are there any license/credentials required to be able to obtain this product from you?
3. Could you tell me how other companies are using the protein?
4. What are your recommended uses for this ingredient?
5. Are there any ingredients that if you were to add your protein to it, that would render the protein unsafe, or cause the protein to lose its potency?
6.What would be the best stabilizing ingredients to go along with the protein?
7. Which of the two kinds that you sell would perform the best and have the longest shelf-life?
8. when/why would you choose the liquid over the freeze-dried version?
9. Are there any restrictions adding it to a cream base that you know of?
10. Any applications you don't advise using it in or for?
11. What are the best fats to combine with the protein for it to be the most effective it can be?
12. When you mention "buffer" I'm assuming you're talking about buffering the protein with other ingredients, in a cream/gel etc.?
13. What is the cost of the protein and in what sizes do you sell them?
14. what is the recommended usage rate of both your products?

Very nice to receive your inquiry. The reply is as follows:
1. Our products are only used for scientific research and have not passed FDA certification.
2. This product can be purchased directly without a license/certificate.
3. This protein is only used for scientific research and is not used for other purposes.
As for the application of this protein, we did not test it. The literature we found is all about the research on the structure and activity-related factors of this protein, providing references: Term = Vitamin % 20 d - binding protein % 20
4. This protein has been analyzed for its immunogenicity, which is good for immunogenicity experiments.
5. We the default buffer is Tris - -based buffer, 50% glycerol, we usually according to the actual circumstances of the protein, to provide the most suitable save buffer to prevent protein instability or failure will not add other ingredients.
6. The form of lyophilized powder theoretically causes the protein to lose water without affecting other functions, but we have not verified it.
7. The shelf life of freeze-dried powder is one year, and the shelf life of liquid state is half a year. When the customer asks for freeze-dried powder or we find that the stability of the protein is not very good, we will advise the customer to choose the form of freeze-dried powder for fear of the loss of protein in the transportation process.
In general, if there is no special case, we will advise the customer to use liquid form.
