anti-beta-endorphin Ab cross reactivity

[Tsunehisa Namba]

Hi All:

   beta endorphin differs in amino acid sequence from species to species.  
We are going to quantitate rabbit serum beta endorphin by RIA.  A company 
sells only anti-rat and anti-human beta-endorphin Abs (polyclonal).  We 
would like to know the cross reactivity of these sera to rabbit beta 
endorphin.  We asked the company technical service but in vain.

   Or otherwise: does somebody know the amino-acid sequence of rabbit 
beta-endorphin?

Thanks

Nam
