 | Western Blot of human, mouse, rat, and goat IgG shows RM120 reacts to human IgG4, in both whole molecule (~150kDa, non-reduced) and heavy chain (~50kDa, reduced) forms. No cross reactivity with other isotypes of human IgG, or mouse, rat, or goat IgG. |
 | A titer ELISA using RM120. The plate was coated with different amounts of human IgG4. A serial dilution of RM120 was used as the primary antibody, followed by an alkaline phosphatase conjugated anti-rabbit IgG as the secondary antibody. |
