RESUMEN
Se da cuenta de un método rápido para la cuantización del flujo citométrico de la fagocitosis en sangre periférica completamente heparinizada (HCPB), mediante la utilización de partículas de látex phycoerythrin-conjugadas de 1µm de diámetro disponibles comercialmente. El método es más rápido y presenta mayor reproducibilidad que la técnica estandar de Bjerknes' (1984) utilizando propidium iodide-teñida Candida albicans, aplicada convencionalmente a la capa leucocitica de sangre periférica pero modificada por HCPB. Tambien damos cuenta de una modificación de Bjerknes' Intracellular Killing Test para permitir su aplicación a HCPB.
ABSTRACT
We report a rapid method for the flow cytometric quantitation of phagocytosis in heparinized complete peripheral blood (HCPB), using commercially available phycoerythrin-conjugated latex particles of 1 micron diameter. The method is faster and shows greater reproducibility than Bjerknes' (1984) standard technique using propidium iodide-stained Candida albicans, conventionally applied to the leukocytic layer of peripheral blood but here modified for HCPB. We also report a modification of Bjerknes' Intracellular Killing Test to allow its application to HCPB.
