Rat IL-2 ELISA, rat B cell kills?

Does anyone know of an ELISA for *rat* IL-2? I have not come across this in
the usual catalogs (R&D, Pharmigen, etc.) and the ones for mouse IL-2 do not
cross-react with rat.
Also, does anyone have experience with complement kills on rat B-cells? I'm
having awful luck with this, and would welcome any suggestions. I use Zymed
rabbit anti-rat IgG+M and Cedarlane's rabbit complement, and I've tried
titrating Ab, C', cell density, and time of incubation, and all that results
is non-specific lysis. [Ab] as high as 100ug/ml, C' at 1:10. and splenocyte
density of 10 x 10^6/ml don't kill, neither does using a 2nd cross-linking Ab
(Goat anti-rabbit). I've considered using PLC to cleave the GPI-linked
C'-inactivators such as DAF, before adding C', but I don't know if this would
really help or just waste more time.
Thanks in advance.
