Re: IHC on Mouse cell cultures
|From:||Greg Dobbin <dobbin@Upei.CA> (by way of histonet)|
If you have a decent amount of the polyclonal antibody you could try
adsorbing it on a mouse cell culture that does NOT have the target
antigen you are staining for. I don't have a specific protocol for you,
but you should be able to find one in most cell culture or virology text
books. Briefly, you incubate the antisera on a washed cell culture at
37 C, rocking the flask periodically to insure maximum adsorption
of non-specific antibodies.
If you only have a small amount of the polyclonal, you may try adding
normal mouse serum to your antibody dilution buffer. Anywhere
from 0.5 to 5% normal mouse serum in the dilution buffer may
"quench" the nonspecific reactants.
Maybe someone else could comment on these suggestions and/or
expand on them. Good luck. Greg
