Hi Dana
Two clones used to be available from the Biological Materials Distribution
Center at the Washington Research Foundation (sorry, I have no current web
address): clone CF-2, which is genus-specific, and clone RR402, which is
Chlamydia pneumoniae (TWAR)-specific. We used them at dilutions of
1:200-1:1000 (CF-2; approx. 1-5 ug Ig/ml) and 1:50-1:250 (RR402; approx.
4-20 ug/ml) after antigen retrieval in 10 mM citrate buffer, pH 6.0,
pressure cooker, StrABC-visualization. Staining is one thing, interpretation
is the other ... Reactivity in mast cells is sometimes observed, as well as
non specific staining of connective tissue. Good luck!
