[Histonet] RE: Humanized mouse monoclonals

[C.M. van der Loos]

Dear Tom,
For the detection of a "humanized" monoclonal antibody on human tissue 
one need a procedure similar to the ARKit: in vitro labeling of the 
primary antibody with a biotinylated goat anti-IgG (of primary 
species) Fab-fragment. Such a kit is available from Molecular Probes 
and called a Zenon-kit 
(http://www.probes.com/products/zenon/zenon.html). According to their 
website it is available for mouse, rabbit and human primary antibodies 
and the label is either biotin or a fluorochrome.

Subject  [Histonet] Humanized mouse monoclonals 


Dear Histonetters,

I was wondering if anyone could provide me with a basic protocol using 
a 
preformed complex of a humanized mouse monoclonal (human Fc ) with a 
biotinylated anti-human IgG to detect antigens in human cryostat 
sections 
- essentially, human on human IHC staining?  I have several antibodies 
with different total protein concentrations.

Thanks
