Question (43392) | Anti-Extracellular matrix protein 1 antibody [EPR6701] (ab126629)

Thank you for contacting us.

In general, the selection of the immunogen varies from antibody to antibody. Some antibodies are raised against synthetic peptides (based ona protein sequence which was derived originally from a DNA sequence), some against protein fragments and others against the full length protein (either purified or overexpressed in another organism) or a cell preparation.

Which specific antibody or protein target do you have in mind?

As for the anti-IgA antibodies - the immunogendepends on the antibody.

Please let me know more details about the products of your interest and I'd be happy to assist you further.
