title: Inconsistencies detected by flow cytometry following immunofluorescence staining with anti-Thy 1 antibodies.
abstract: A number of inconsistencies have been observed when anti-Thy 1 reagents are used for immunofluorescence. (1) When indirect staining procedures are used, the differences in staining between high and low Thy 1 populations may be obscured, (2) with both direct and indirect staining methods, variable peaks of 'low Thy 1' cells can be seen, apparently derived from the high Thy 1 population by loss of antigen and/or antibody during the staining procedure. This disparity is quite variable, appears to occur at random and is independent of a large number of technical variables tested. Similar inconsistencies are not apparent with other lymphocyte markers (e.g., Lyt 1, Lyt 2, TLa, peanut agglutinin, H2, Ig).
