The manual sequencing of the tryptic peptic from the alpha and beta chains of dog hemoglobin is described, including evidence for the existence of two alphaT-13 peptides and thus 2 alpha chains, one with threonine and one with alanine at position 130. Although the actual sequence was published in 1970, the evidence on which it was based has not previously appeared.
