Has this IgG Fc fragment protein been checked for contamination with F(ab) fragments?
Do you have any other Fc fragment proteins with higher purity than 95%?

Thank you for contactingus.
This Fc fragment protein shows no reaction to F(ab) on immunoelectrophoresis. We will guarantee this product to be free from F(ab) fragment contamination. Unfortunately, we do not currently have any other purified human IgG Fc fragment proteins in our catalog.
I hope this helps, please let me know ifyou need any additional information.
