Hi, I designed a construct encoding extracelluar domain of anti-CD3 antibody and transmembrane domain of CD8. Does anyone have any experience of detect membrane anchored anti-CD3 antibody? what antibody or protein should I use for Western blot or ELISA method? Or what is the protocol to use PBMC stimulation method to detect anti-CD3 antibody? or is there any anti-CD3 antibody dependent cell line? Thank you
