Abstract

métodos para a detecção da expressão do ligante 1 de morte programada por célula (pd-l1) de células de neoplasia. aspectos dos métodos incluem análise citométrica de uma suspensão de células marcadas para quantificar a expressão de pd-l1 de célula para detectar se uma célula neoplásica que expressa pd-l1 acima de um limite predeterminado está presente na amostra de neoplasia. além disso, são também providos kits que encontram uso na prática dos métodos em questão.
