every two-fold

Portuguese translation: (em série / serialmente) a cada duas vezes

15:21 Oct 7, 2008
English to Portuguese translations [PRO]
Tech/Engineering - Genetics
English term or phrase: every two-fold
"To measure anti-Her-2/neu antibody titer in the serum, the serum was diluted serially every two-fold from 1:50 (with PBS containing 1% FBS, 0.09% azide) , followed by culture with TAUF, tumor cells expressing Her-2/neu, at 4 °C for 60 minutes."

O problema está neste trecho: "was diluted serially every two-fold from 1:50 "

Realmente não entendi o significado de "every two-fold" nesta frase. Peço uma ajuda dos amigos para desvendarmos

Obrigado

a cada múltiplo


Explanation:
Também nunca tinha visto, mas dando uma olhada nessa definição (http://www.thefreedictionary.com/twofold), parece que "twofold" pode ser sinônimo de "multiple". Melhor aguardar outras opiniões antes de decidir.

a cada duplicação


Explanation:
"Two-fold" ou "twofold" significa duplo, duplicado, duplicação, daí a minha sugestão.

  -> Obrigado, Edimilson. No meu entender, a sua sugestão também faz sentido, e poderíamos usar "a cada multiplicação", mas o termo original é específico nesse sentido e de certa forma inviabiliza-a, pois pode ser por dois ou mais.
agree  Alexandra Gouveia: i.e. "Prepare uma série de diluições ao dobro ..." http://www.laborclin.com.br/Tecnicas/manuais/sorologia/fator...
