Hi Everyone,
I recently set up a construct like cd8a signal peptide-target gene-cd8a transmenbrane domain. But I can't detect the target gene expression by FACS. Supposedly, the target gene should be expressed on the membrane because of the transmembrane domain. What funny is I can detect the expression by intracelluar staining. So, I'm really confused. Is it the problem of the signal peptide or the transmembrane domain? Since I can detect the gene expression, I think it's not the target's fault. Need help guys. Thank you!
Best,
Oscar
