HL-sixty tissues was in fact incubated having MMRI-dos0-PE otherwise isotype manage-PE (10?g/ml) toward freeze to possess 20 min
Antibody coated cells were then incubated at 37°C/5% CO2 for the indicated times to allow internalisation. After incubation, a secondary GAM IgG-AF488 antibody was applied to the samples for 20 min on ice to detect remaining surface antibody and compared to the total (surface and internalised) PE staining. Cells were fixed in 1% paraformaldehyde/PBS followed by flow cytometry analysis. Relative MFI was calculated as a percentage of staining at 0 min.
Colony forming gadgets (CFU)
Frozen CB cells were incubated with MMRI-20 mAb followed by GAM IgG-AF488 (Invitrogen). Subsequent staining with a Lin stain was performed. DAPI – Lin – CD302 + or CD302 – fractions were FACS isolated and resuspended in IMDM media (Stemcell Technologies). Equal numbers of each sorted fraction were plated at 1.5–2.5×10 4 cells/plate in semi-solid methylcellulose medium (MethoCult Classic, Stemcell Technologies). Plates were cultured at 37°C and 5% CO2 for 12–14 days prior to counting of multi-lineage, myeloid and erythroid colonies in wells with a light microscope.

Target cells (5×10 3 ) were mixed with 5×10 4 C57BL/6J female mouse (Animal Resources Centre, Perth, Australia) spleen effectors (E), 1000U of human IL-2 (Invitrogen) and the indicated concentrations of MMRI-20 or isotype control in triplicate.Read More »HL-sixty tissues was in fact incubated having MMRI-dos0-PE otherwise isotype manage-PE (10?g/ml) toward freeze to possess 20 min
