Flow zap70 expression
WebT-cells are a subset of lymphocytes that play a large role in the immune response. The TCR (T-cell receptor) is a complex of integral membrane proteins that participate in the activation of T-cells in response to an antigen. Stimulation of TCR is triggered by MHC (major histocompatibility complex) molecules on cells with the antigen. WebNov 16, 2004 · ZAP70 expression in chronic lymphocytic leukemia (CLL) correlates with the presence of unmutated immunoglobulin chain (IgVH) genes and with poor clinical outcome. We hypothesised that expression of ZAP70 may be related to the methylation status of the ZAP70 gene. ... which are relevant to the current flow cytometric assays for …
