Southern blot analysis of genomic DNA using theHp β cDNA probe.

Genomic DNAs (7 μg) from a patient (NK) with anhaptoglobinemia (lane A), from an individual with hypohaptoglobinemia (lane H) and from a control individual (lane N) were digested by SacI. The band indicated by an asterisk was unexpected. The sizes (kb) of the hybridized fragments are indicated.
