LDS 651
LDS 651 is an analog of LDS 751. LDS 651 has almost identical intracellular staining pattern to LDS 751. LDS 651 is optimized to be excited by Violet Laser while LDS 751 is excited by Blue Laser at 488 nm. Both LDS 651 and LDS 751 are cell-permeant fluorescent dyes. Although both of LDS 651 and LDS 751 bind to DNA, they may be excluded from the nucleus and bind to other cellular structures such as the polarized membranes of mitochondria. Cautions need be taken when LDS 651 and LDS 751 are used for analyzing live cells and their fluorescence as being indicative of nuclear status. LDS 651 and LDS 751 might be used to separate red blood cells from nucleated cells.
Flow cytometric analysis with LDS 651. Jurkat cells were stained with LDS 651 as per the protocol and response was measured with NovoCyte flow cytometer using PerCP channel.
