title: [Genetic polymorphism of polyacrylamide gel electrophoresis loci in patients after non-myeloablative allogeneic peripheral blood stem cell transplantation].
abstract: OBJECTIVE
  To understand the information of donor and recipient in the mixed hematopoietic chimerism after non-myeloablative allogeneic peripheral blood stem cell transplantation(NM-APBSCT).
  
  
  METHODS
  DNA samples were extracted with phenol/chloroform method and were amplified by PCR technique in heparin-blood or heparin-bone-marrow. The PCR products were analyzed using polyacrylamide gel electrophoresis and silver staining means.
  
  
  RESULTS
  The amplified fragment length polymorphism was found in the short tandem repeat loci of 10 healthy persons and 8 leukemia patients who were not treated with hematopoietic stem cells transplantation; the bands of silver staining originated from donors and recipients were found in 3 patients after NM-APBSCT, but the brightness in the bands of donor and recipient was different.
  
  
  CONCLUSIONS
  Polymorphism for mixed hematopoietic chimerism can be estimated timely, sensitively and exactly; and the results may be used to guide adoptive immunotherapy for patients after NM-APBSCT. The silver means were simple without contamination of isotopes and without using special equipment. The methods may benefit common hospitals to develop work in this respect.
