Hi there!
We are applying L.lactis for expression of a heterogeneous antigen using a cell wall anchor subunit. Cloning process has been verified and expression optimization is up now but I'm getting confused with the whole cell ELISA result. It seems control population have different properties at the surface such as, more tight attachment to the wells and agglutination through mouse antiserum treatment despite of test population. Can any one help me out to find an explanation for what I have observed repeatedly?
Any idea is welcomed
Thanks a lot
