title: A comparative study of albumin variants found in Brazil.
abstract: 10 rare albumin variants found in Brazil have been compared with 6 others, discovered elsewhere, through horizontal starch gel electrophoresis in four buffer systems. Belém V can be clearly distinguished from Naskapi but shows the same mobility as Máku (= Belém III) in two different pHs. Coari II, Manaus I and Porto Alegre II can be separated from all others in three buffer systems. Belém II (= Mexico) and Belém I also show unique patterns, but Coari I, Porto Alegre I and Belém IV could not be distinguished from Santa Ana. The possibly synonymous Belém III-Belém V-Máku should have originated from an Amerindian gene pool, but Coari I-Porto Alegre I-Belém IV-Santa Ana may have a Caucasoid origin.
