I'm doing some fluorescence using the biotynilated
antibodies/streptavidin Texas Red. I'm using 4% parafolmadehyde and 0,5%
Triton for the fixation /permeabilization steps.
My problem is in the background. I started using BSA 3% whitout luck and
then switch to 5% calf serum. The background was reduced but is still there.
Please any suggestion or good protocols are wellcome
BTW these are NIH 3T3 cell lines
