Anti-K1 (Kell) Antibody Expressed in Maternal Breastmilk: A Case Report of a Neonate with Multiple Intrauterine Transfusions and Postnatal Exposure to Kell Antibody in Maternal Breastmilk
Hemolytic disease of the fetus and newborn is a common consideration in newborn medicine, especially among the jaundiced. Maternal breastmilk provides numerous benefits to the infant, including nutrition and immunologic factors. Here, we present an infant who received three intrauterine transfusions for anemia secondary to anti-K1 (Kell), anti-C, and anti-e antibodies and whose maternal breastm...
متن کاملDetermination of brucella immunoglobulin G agglutinating antibody titer with dithiothreitol.
The routine brucella agglutination test measures both immunoglobulin M (IgM) and IgG brucella antibody titers; however, only an elevated IgG titer is significant for differentiating active from inactive disease in patients with symptoms lasting 3 or more weeks. The IgG antibody titer can be determined by treating the serum wih 2-mercaptoethanol to inactivate the IgM brucella antibodies while le...
متن کاملPartial purification of a boar sperm membrane protein inducing sperm agglutinating antibody.
For the development of immunological contraception, attention is being concentrated on the possibility of using a sperm membrane antigen. Boar sperm membrane was extracted with triton-X 100 and fractionated by Sephadex G-150 column chromatography. The glycosylated and nonglycosylated portions of protein peaks from the gel filtration were obtained by fractionating on concanavalin A-Sepharose and...
متن کاملCharacterization of the blood group Kell (K1) antigen with a human monoclonal antibody.
A human monoclonal anti-Kell (K1) antibody secreted by an Epstein-Barr virus (EBV)-transformed B-cell line was used for binding studies and immunopurification of the K1 blood group antigen. The 125I-labeled antibody bound to 4 to 5 x 10(3) and 2.5 to 3 x 10(3) antigenic sites on K1K1 and K1K2 erythrocytes, respectively, with an affinity constant of 5 x 10(8) mol/L-1. Immunoprecipitation analysi...
متن کاملPossible suppression of fetal erythropoiesis by the Kell blood group antibody anti-Kp(a).
Antibodies to antigens in the Kell blood group system are usually immunoglobulin G, and, notoriously, anti-K, anti-k, and anti-Kp(a) can cause severe hemolytic transfusion reactions, as well as severe hemolytic disease of the fetus and newborn (HDFN). It has been shown that the titer of anti-K does not correlate with the severity of HDFN because, in addition to immune destruction of red blood c...
