anti mouse-IgE conjugate (AP)?

[Thomas Schnibbe]

...I'm desparately looking for an anti mouse-IgE conjugate (alkaline
phoshatase). For reasons I don't know it doesn't seem to be available at
major providers. 
Anybody working with it? Where did you get it?
Looking forward to any kind of help, 
Thomas Schnibbe
