There are several different dyes that can be used in these assays including propidium iodide PI 3 4 7-amino actinomycin-D 7-AAD Hoechst 33342 and 33258 and 46-diamidino-2-phenylindole DAPIFor example Chopra S et al labeled mouse bone marrowderived dendritic cells and paw single cell suspensions with 05 μgml DAPI from. This six-channel five colors and one FRET channel real-time PCR instrument combines advanced optical technology with precise temperature control to deliver sensitive reliable detection for singlexplex or multiplex reactions. Perform fluorescence activated cell sorting FACS or flow cytometric analysis.

It is a technique that is used to detect specific proteins in the given sample. Download our membrane staining summary. The properties measured include a particles relative size relative granularity or internal complexity and relative ﬂuorescence intensity.

Harvest wash the cells and adjust cell suspension to a concentration of 1-5 x 10 6 cellsmL in ice-cold PBS 10 FCS 1 sodium azide. Flow cytometry multicolor experiments may need compensation when there is fluorescence spillover Figure 1Pairing fluorochromes based on antigen density fluorochrome brightness and separating by channels helps to minimize the effects from spillover and may remove the need for compensation from smaller experiments. Centrifuge at 1500 rpm for 5 min at 4C.

Flow cytometry has been extensively exploited in immunology hematology and oncology to define cell populations via intrinsic scatter properties cell surface antigen expression and other fluorescence parameters 1-3Our insights into blood lineage development and disease are a result to a significant degree of the continuous refinement of. There is no need to use sodium azide in these buffers it will.
