Polyacrylamide gel photograph showing TNF polymorphisms. Lanes 1–4 correspond to the four reactions used to identify the four previously documented haplotypes of the three biallelic polymorphisms, TNF+488, −238 and −308. The upper visible band is the control band. A positive reaction is seen in lanes 1 and 2, giving a result of TNF+488G, −238G, −308GA. Lanes 5–12 represent the remaining individual biallelic polymorphisms as follows: lanes 5 and 6: TNF−1032T,C; lanes 7 and 8: TNF−865C,A; lanes 9 and 10: TNF−859C,T; lanes 11 and 12: TNF−380G,A. In each case, the lower band is the control band. Positive reactions are seen in lanes 5,7,9 and 11 giving the result of TNF−1032T, −865C, −859C, and −380G.
