Bovine Albumin 30%
Serological albumin was first recognised as a potentiator of certain antigen-antibody interactions in 1945 by Diamond. Since then, methods employing serological albumin have been widely used for the detection or quantitation of antibodies. Serological albumin has also been shown to enhance the sensitivity of the indirect antiglobulin test for some antibody specificities.
When used by the recommended techniques, the reagent will not affect the first stage of haemagglutination (antibody uptake) but it will enhance the second stage (agglutination) by allowing the antibody-coated red cells to come closer together than they would in a saline medium without additives (see Limitations).
Lorne 22% and 30% Serological Albumin are prepared from a mixture of bovine serum albumin, and buffered saline. The polymer content of the Polymer Enhanced BSA (Cat # 453) is increased naturally by a process modification. No artificial avidity enhancers or high molecular weight agglutination potentiators are added to any BSA preparation. None of the BSA reagents do contain sodium caprylate. Each BSA reagent is supplied at optimal dilution for use with all the recommended techniques stated below without the need for further dilution or addition. For lot reference number and expiry date see Vial Labels.

Coombs Control Cells - 970
In 1945, Coombs, Mourant and Race described the use of anti-human globulin serum for detection of red cell-bound non-agglutinating antibodies and the antiglobulin (Coombs) test was rapidly applied. One cause of false negative antiglobulin tests is improper washing of the cells which results in free globulin molecules being present with supposedly washed cells and these globulins neutralise the antiglobulin serum when it is added. A negative result in an antiglobulin test should only occur when anti-human globulin is added to red cells that are not sensitised. To show that test cells were properly washed and that no neutralisation has occurred, antibody-coated cells are used as a positive indicator.
Anti Jka - 323
The Jka and Jkb antigens were reported in 1951 and 1953 respectively. Anti-Jka and anti-Jkb can both show dosage and are notorious for their evanescence: antibody titres that rise after stimulation but quickly drop, often to undetectable levels. Kidd system antibodies have been implicated in delayed and immediate Haemolytic Transfusion Reactions and Haemolytic Disease of the Newborn.
Anti H Lectin
The H antigen is part of the Hh system and is found on all red cells except those of Oh (hh) Bombay phenotype, which is extremely rare. H is the precursor of A and B and so group A and B people have less H than O people.
Toxoplasmosis Latex Test Kit - 033
When used by the recommended techniques, latex particles in the reagent will agglutinate (clump) in the presence of Toxoplasma gondii antibodies. No agglutination generally indicates absence of the Toxoplasma antibody
Anti Lea (monoclonal)
The Lewis system antigens are not an integral part of the red cell membrane and are produced by tissue cells and found primarily in plasma and watery secretions. Red cells acquire Lewis antigens by absorption from surrounding plasma. The amount of Lewis antigen expressed on a cell can vary with the cell’s ABO phenotype. Anti-Lea and Anti-Leb have not been associated with Haemolytic Disease of the Newborn, but examples of Anti-Lea have caused Haemolytic Transfusion Reactions.
