p24 protein of a human T-lymphotropic virus type-I (HTLV-I) producing cell line (TCL-Kan) reacts with some normal pregnant women's sera.
Some HTLV-1 antibody carrying pregnant women, who are rated by the gelatin particle agglutination (PA) method, show no expression of HTLV-I antigen in their peripheral blood lymphocytes. Paying attention to this fact, the authors recently studied the reaction of the antibody contained in the PA-positive sera with the antigen protein used for the PA method. This study demonstrated that the protein responsible for non-specific reaction has a molecular weight of 24,000 and that the isoelectric point of this protein differs from that of HTLV-I specific protein.
