Question (77115) | Native Human IgG FC fragment protein (ab90285)

Go to datasheet (ab90285)

Question

Is this a fragment of an IgG1 antibody subclass?

Answer

We prepare ab90285 from human plasma having a mixture of IgG1, IgG2, IgG3 and IgG4.  After digestion and purification, the final product should similarly be a mixture of the Fc regions for the four subclasses.
