摘要:
Flow cytometric methodology is provided for simultaneous determination of (1) ABO and Rh(D) typing of human red cells, (2) natural isoantibodies in plasma, and (3) screening for alloantibodies in plasma. The method includes (a) the use of a unique combination of fluorescent labelled antibodies to A, B and Rh(D) antigens to carry out (1); (b) different sized beads coated with blood group substances A & B to carry out (2); and (c) the differential fluorescent labelling of screening reagent red blood cells for flow cytometric analyses to carry out (3). The routine ABO and Rh(D) typing and antibody screening of human blood for both isoantibodies and alloantibodies can be determined in three individual reactions compared to 7 to 10 tests currently performed in blood banks.
摘要:
Methods and compositions are provided for an inexpensive safe vaccine for hepatitis infection. Immunogenic polymerized human albumin free of other hepatitis related immunogens is employed in a physiologically acceptable carrier as a vaccine for protection against hepatitis.
摘要:
Methods and compositions concerned with the a determinant of hepatitis B antigen, providing immunogens and antibodies. The immunogens can serve as vaccines.
摘要:
Novel oligopeptides are provided having serologic activity for the a determinant of hepatitis B virus surface antigen. Included in the oligopeptide chain are a sequence of at least two cysteines and a lysine in proximity to the cysteines. The oligopeptides can find use in immunoassays, the formulation of vaccines, and the production of antisera.
