AlloSeq Tx 17 es una innovadora solución para tipaje HLA por NGS (Next Generation Sequencing) o secuenciación masiva, que emplea la tecnología de captura.

El kit permite secuenciar los genes HLA-A, -B, -C, -E, -F, -G, -H, -DRB1, -DRB3/4/5, -DQA1, -DQB1, -DPA1, -DPB1, MICA y MICB, con una cobertura máxima de los 17 loci (todos los exones de todos los genes). La resolución a nivel de alelos da lugar a bajos porcentajes de ambigüedad.

El kit incluye los reactivos para preparar las librerías utilizando transposones unidos a microesferas, índices para la identificación de las muestras en un solo tubo, sondas complementarias biotiniladas para capturar las regiones de interés y reactivos para enriquecer las regiones capturadas para su posterior secuenciación.

La secuenciación se realiza en plataformas Illumina (Miseq, MiniSeq o iSeq) y las secuencias resultantes se importan y analizan con el software de análisis de datos AlloSeq Assign, para determinar el genotipo de las muestras.

La secuenciación mediante captura híbrida permitirá en el futuro el estudio de nuevas regiones de interés mediante el agregado de sondas específicas, sin necesidad de alterar el flujo de trabajo.
