	Daudi has been genotyped for HLA-A, -B, and -C.  However I don't
know that the haplotypes have been examined.  The genotype is discussed in:

	Browning MJ, et al.
	The HLA-A,B,C genotype of the class I negative cell line Daudi
	reveals novel HLA-A and -B alleles. 
	Tissue Antigens. 1995 Mar;45(3):177-87.
