Lectin for checking blood type, blood type checking reagent containing the lectin, and method of checking blood type using the blood type checking reagent

Abstract

Lectin for checking a blood type is extracted from seeds of bitter gourd, balsam pear, or Momordica charantia. A blood type checking reagent includes the lectin. The lectin extracted from seeds of bitter gourd preferably has a molecular weight between 100,000 and 170,000 measured with poly-acrylamide gel electrophoresis in existence of sodium dodecyl sulfate (SDS-PAGE). A method of checking a blood type includes the steps of: extracting lectin from seeds of bitter gourd, balsam pear, or Momordica charantia; preparing a blood type checking reagent containing the lectin; and checking a blood type using the blood type checking reagent.

1 . Lectin for checking a blood type being extracted from seeds of bitter gourd, balsam pear, or  Momordica charantia.    
   
   
       2 . A blood type checking reagent, comprising lectin extracted from seeds of bitter gourd, balsam pear, or  Momordica charantia.    
   
   
       3 . The lectin according to  claim 1 , wherein said lectin has a molecular weight between 100,000 and 170,000 measured with poly-acrylamide gel electrophoresis in existence of sodium dodecyl sulfate (SDS-PAGE).  
   
   
       4 . The blood type checking reagent according to  claim 2 , wherein said lectin has a molecular weight between 100,000 and 170,000 measured with poly-acrylamide gel electrophoresis in existence of sodium dodecyl sulfate (SDS-PAGE).  
   
   
       5 . A method of checking a blood type, comprising the steps of: 
 extracting lectin from seeds of bitter gourd, balsam pear, or  Momordica charantia;      preparing a blood type checking reagent containing the lectin; and    checking a blood type using the blood type checking reagent.    
   
   
       6 . The method of checking a blood type according to  claim 2 , wherein said lectin has a molecular weight between 100,000 and 170,000 measured with poly-acrylamide gel electrophoresis in existence of sodium dodecyl sulfate (SDS-PAGE).
