Hemoglobin subunit delta is a protein that in humans is encoded by the HBD gene. The delta (HBD) and beta (HBB) genes are normally expressed in the adult: two alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin. Two alpha chains plus two delta chains constitute HbA-2, which with HbF comprises the remaining 3% of adult hemoglobin. Five beta-like globin genes are found within a 45 kb cluster on chromosome 11 in the following order: 5"-epsilon--Ggamma--Agamma--delta--beta-3".

Optimal dilution of the HBD antibody should be determined by the researcher.

A recombinant human protein corresponding to amino acids V2-H147 was used as the immunogen for the HBD antibody.

After reconstitution, the HBD antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
