I made HA-tagged FANCA FL construct by myself, and checked the expression of both HA and FANCA protein a few days ago. It turned out I could see the FANCA band when I used FANCA antibody, but could not see HA band when I used HA antibody. HA is fused in the N-terminal of FANCA. I tried two HA antibodies. Does anyone have suggestions? How can I solve this issue? Thank you!
