Question (69181) | Natural Protein A (ab7399)



Inquiry: Hey I have a question about protein A protein (ab7399) - does it have a histag? Or no? how was the purification done then? Thanks.

Thank you for contacting us.


Our Protein A is purified using a process that is considered proprietary so unfortunately I am unable to provide any details. Please let me know if I can be of further assistance.
