FaiI to extract DNA from heparinized blood for HLA analysis.?

I would like to extract human DNA from leukocytes for HLA analysis. But it does not work capably when we test for HLA because we use heparin as anti-coagulants. What can I do to remove heparin from precipitated DNA?


Answers:    Have the taster drawn in an ACD (acid citrate dextrose) yellow-top tube. ACD solution is available contained by 2 formulations - A & B - for immunohematology tests as DNA and HLA phenotyping used for paternity evaluation and determining transplant compatability. ACD prevents coagulation by binding calcium beside little effect on cells and platelets. Dextrose act as a red blood cell nutrient and preservative by maintaining rbc possibility.
I have no perception, but I'm totally smitten.
