Serum Hp phenotype determination of patients by immuoblot. Polyclonal antibody against human Hp was used to binding the Hp on the blots. Lane 1 is the Hp protein standard containing Hp β, α-1 and α-2 chains. Lane 2–25 shows the serum Hp phenotype from patient 1 to patient 24 listed in Table 1. Patients who have Hp β and α-1 chains indicate a Hp 1-1 type; patients with Hp β and α-2 chains are Hp 2-2 type and patients with all the Hp β, α-1 and α-2 chains indicate a Hp 2-1 type.
