Abstract
A method and kit for typing platelets in whole blood for human leucocyte antigens (HLA). A panel of HLA antigens is made on a microtiter plate. Each well is contacted with serum to be typed and the amount of reaction is followed with anti-human (Fab '2) alkaline phosphatase and disodium p-phenylphosphate.
Claims2
A kit for assaying platelets comprising;
- a plate having a plurality of wells, each well containing a monolayer of platelets of a single type of HLA, said platelets having been previously washed with 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate to thereby enhance bonding between the bottom of each well and the monolayer of platelets contained therein, wherein the plurality of wells contain antigens to more than one type of HLA;
- and
- in a separate container, a supply of (Fab '2) anti-human IgG conjugate alkaline phosphatase.
