Evaluation of Two Methods of Isolation, Differentiation and Staining of Lymphocytes by Microlymphocytotoxicity Assay
Abstract
Microlymphocytotoxicity assay is routinely used to develop the cross match. Donor lymphocytes, in this assay, are target to anti-HLA alloantibodies that could be present in the receptor sera and because of that, is important to define the methodology of isolation, differentiation and staining of lymphocytes. Due to cellular fragility of lymphocytes, mainly B lymphocytes, methodology of isolation, differentiation and staining show direct influence in the reaction. The aim of this study was to compare two methodologies of isolation, differentiation and staining of lymphocytes by ficoll-hypaque/fluorobeads and tripan blue/fluoroquent respectively. Twenty-seven reactions were developed using ficoll-hypaque/tripan and 42 by fluorobeads/fluoroquent methods. The results showed that fluorobeads/fluoroquent method had better performance in the process of isolation, differentiation and staining for both lymphocytes populations, T and B.
