Summary

Automatic Translation

A modificação da membrana celular das células vermelhas do sangue (RBC) com poliglicerol hiper-ramificado (HPG) é apresentada. Hemácias modificadas foram caracterizadas por partição de fase aquosa dois, fragilidade osmótica e lise mediada pelo complemento. A camuflagem de proteínas de superfície e antígenos foi avaliada usando a citometria de fluxo e Sistema de Digitação Micro (MTS) cartões de fenotipagem de sangue.
