Mixed agglutination on solid phase (MASP) and its inhibition (IMASP): two immunoassays for soluble ABH group-specific
Abstract:
Two immunoassays are described: mixed agglutination on solid phase (MASP) and inhibition of mixed agglutination on solid phase (IMASP). The MASP assay permits detection and measurement of soluble A, B and H high molecular weight glycoproteins in secretor individuals with a sensitivity at least 800 times greater than the usual inhibition technique. Both secretors and non-secretors can be typed by the less sensitive IMASP test which also permits the detection of low molecular weight A, B and H substances.

Blood Transfusion and Agglutination
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
