We are cuurently looking at similar markers in our cell lines, and have noticed a similar effect immediately after removing the cells from plastic. What we do is trypsinise the cells to lift them off, neutralise immediately with medium containing 10% FCS, spin down and re-suspend in complete medium and incubate for 30 min at 37deg before staining. This seems to allow the markers to re-generate. perhaps this method will help your problem.
