Detection of human IgG4 in monkey serum.
Sandwich ELISA using RM120 as the capture
antibody, and biotinylated anti-human light
chains ( κ+ λ) antibody RM129 as the detection
antibody, followed by a HRP conjugated streptavidin.

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.

ELISA showing RM120 does not react to monkey
IgG. The plate was coated with Rhesus monkey IgG.
A serial dilution of RM120 and a monkey IgG binding
antibody (positive control) was used as the
detection antibody.
