CONVERSION OF RED BLOOD CELLS A, B, AND AB USING a-N-ACETYLGALACTOSAMINIDASES AND a-GALACTOSIDASE

摘要

This invention relates to enzymatic removal of type A and B antigens from blood group A, B, and AB reactive cells in blood products, and thereby converting these to non-A and non-B reactive cells. The invention further relates to using unique a-N-acetylgalactosaminidases and a-galactosidases with superior kinetic properties for removing the immunodominant monosaccharides of the blood group A and B antigens and improved performance in enzymatic conversion of red blood cells.
