Fetal monitoring is therefore best undertaken by serial ultrasound examination to detect early evidence of fetal oedema. I'm currently 32 weeks and the baby is showing no signs of problems as yet. Rat Monoclonal Anti-Kell Antibody (214711). Antibody first published in: Chu et al. Once anti-Kell antibodies are identified in a pregnant woman, the titers should be measured, history of previous pregnancies and blood transfusions ascertained, and the Kell status of the husband determined. If the husband is Kell negative, the fetus will be Kell negative, and no further investigations are required. Some of these antigens are highly immunogenic, and after the ABO and Rh blood group systems, they are the most common immunogenic group for red blood cells. The Kell antigens are located on the red blood cell transmembrane glycoprotein known as CD238, and consist of a large group of 35 antigens. Order anti-KEL anticorps ABIN6925373. Tested Reactivity: Mouse. Rh (anti-D, anti-E, anti-c ), Kell (anti--K), Duffy (anti-Fya) antibodies are the most likely to cause HDFN requiring intrauterine transfusion. This is performed routinely in most hospitals. Protocols. 2008 Feb;136(2):151-4. doi: 10.1016/j.ejogrb.2007.03.003. anti-KEL antibody (Kell Blood Group, Metallo-Endopeptidase) (AA 633-732) Primary Antibody. G-202-C . The KEL (CD238) gene encodes a type II transmembrane endopeptidase, Kell, that shares a consensus sequence with a large family of zinc-dependent endopeptidases. I had 2 sons , one in 1988 and another in 1991. Lapin KEL Polyclonal anticorps C-Term pour WB. Goat Anti-Mouse IgG Biotinylated Antibody. After delivery the infant's MN antigen status should be determined, because a negative direct Coombs' test may be found even when M antigen is present in the infant and hemolysis is occurring. I contracted the anti-kell antibody in 1986 from a blood transfusion. 3 Citations 1 Review . The Kell blood group system is named for an antibody that induces hemolytic disease of the newborn, which is specific for the K (KEL1) antigen. None of the other 18 infants required any therapy for HDN. A second pregnancy with titers 1:32 had an infant who needed phototherapy to read the HDN. In one article, out of 20 cases of anti-Jka, 16 required monitoring with titers only, while 4 were followed with more diagnostic tests. 1, 2 Individuals with this phenotype can be immunized to Kell Blood Group System antigens and form a universal antibody, named anti-Ku (or anti-K5). Anti-Kell is associated with an inhibitory effect on fetal erythropoiesis, which is independent of antibody concentration. Anti-k (KEL2) antibodies react with the erythrocytes of more than 99% of the random population. Because the RBC precursors (the progenitor cells) do not have hemoglobin, less bilirubin is released. Select up to 5 products from below to compare or request more information. Kell Antibody (A-10) is available as both the non-conjugated anti-Kell antibody form, as well as multiple conjugated forms of anti-Kell antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor ® conjugates. Current clinical management of anti-Kell alloimmunization in pregnancy Eur J Obstet Gynecol Reprod Biol. A Kell positive father frequently is the cause behind the inability of his partner to bear a healthy infant after the first Kell negative pregnancy, which the authors note is precisely the circumstance experienced with women who had multiple pregnancies by Henry. If a mother has a clinically significant antibody during pregnancy, the neonate should be assessed for the corresponding antigen at birth through cord-blood testing. The anti-Kell antibody is predominantly IgG and consequently should be present in colostrum and early breast milk. Typing paternal RBCs for antigens that correspond to maternal antibody may aid in the prediction of hemolytic disease of the fetus and newborn. Epub 2007 May 3. (Sorry I implied above that being negative for the Coa antigen is common; Malcolm has stated that much more accurately.)

This KEL antibody is un-conjugated Application Aggregation (AGG), Enzyme Immunoassay (EIA), Haemagglutination (H), Immunohistochemistry (Frozen Sections) (IHC (fro)) Specificity This antibody recognises CD238, also known as the kell blood group antigen Kpbc. It is one of the major antigenic systems in human red blood cells and is important in transfusion medicine because the antibodies can cause severe reactions to transfusion of incompatible blood and hemolytic disease in newborn infants (HDN). Anemia associated with anti-K-induced HDFN can be particularly severe not so much because of destruction of K-positive circulating fetal red cells, but because the antibody suppresses erythropoiesis by attacking immature K-positive red cell precursors in the bone marrow. I am currently on my second pregnancy since contracting the Anti Kell Antibody (to name just one) after receiving a blood transfusion in 1994 after my 1st pregnancy.My second pregnancy started normally with my head in a bowl in late 1999 I discovered I had these antibodies during routine blood checks at 12 weeks.
