Hela MHC type?

Hi,

We typed (our) HeLa as HLA-A*6802, -B*1503 or -B*1537, and -Cw*1604 
using RT-PCR [Johnson and Mook-Kanamori, JBC 275 (22) 16643-9 (2000)]. 
These were the best matches from single sequencing runs of PCR amplified 
cDNAs, not rigorously checked.  HeLa have been serologically typed as 
HLA-A3, -A28, -Bw15, and Bw35 [Espmark et al Tissue Antigens 11:279-86 
(1978)] and genetically typed as HLA-A68 (a subtype of A28), -B75 (a 
subtype of B15) and NEGATIVE for B35 [Benham, Gromme and Neefjes, 
J.Immunol. 161:83-89 (1998)].

Obviously, these findings disagree.  You might consider HLA class I 
typing your own HeLa with the RT-PCR procedure that we described 
[Johnson, Biedermann and Mook-Kanamori, J. Immunol. Meth. 233:119-129 
(2000)].  It's very easy, quick, and requires only 4 primers.

I hope this helps.
