Fluorescence polarization measurement during the progress of fluorochromasia has been used to study the response of human lymphocytes to phytohaemagglutinin (PHA) and to tumour-associated antigens, as a basis for the detection of malignant disease.
For immunofluorescence staining of human lymphocytes the Lysed Whole Blood Method was used according to Becton-Dickinson protocol.
Through rigorous optimization and quality control, we have identified parameters important to plate sorting and recommend the use of the 70 mum nozzle and low flow and threshold rates for analysis of rare populations of human lymphocytes.
E.I.C., P.P. and A.K. analysed proteome of human lymphocytes by mass spectrometry.
We believe that our use of primary human lymphocytes and two activation strategies specifically chosen to model natural immune activation via T cell co-stimulation (CD3/CD28) and T cell help for B cell activation (anti-CD40/IL2/IL10) is more representative of biology in this context.
Furthermore, apart from the usage of reporter-gene based assays, the inhibitory activity of the extracts from R. parviflora was also assessed using activated human lymphocytes (PBLs; biological targets of HIV including CD4+ T cells, monocytes, dendritic cells, etc).
This study evaluates the effects of PET imaging using isolated peripheral human lymphocytes sampled before and after a standard PET scan in a patient.
A limitation of this study is the use of an immortalized human lymphocyte cell line to evaluate the biological activity of PLGA encapsulated IL-1 ra.
However, the assay does not discriminate complement activating HLA-Ab from other HLA-Ab, as the use of rabbit complement and human lymphocytes artificially enhances lysis (66), and several groups have suggested cell lysis is not the major mechanism of graft damage, nor the most accurate read-out of HLA-Ab-mediated complement activation in vitro (67, 68).
hPBMCs were isolated from the blood of healthy volunteer blood donors using human lymphocyte separation medium (IBL, Japan), and 1 × 10 cells were cultured in RPMI.
