BioLegend'sLEGENDScreen(TM) Human Cell Screening (PE) Kit contains 332 PE-conjugated monoclonal antibodies to cell surface markers as well as 10 mouse, rat, or Armenian hamster Ig isotype controls. All of the antibodies have been pre-titrated to optimal concentrations, arrayed on four 96-well plates, and lyophilized in a ready-to-use format. This kit can be used to screen cell lines and primary cells (PBMCs, bone marrow derived cells, and cells isolated from tissues). There are blank wells on the plates for users to add their choice of markers. The end user can also choose to screen cells of interest directly or co-stain with other markers labeled with different fluorochromes. Positive hits from the screening can be quickly identified based on the plate map, and the catalog number and clone information can be obtained using the tables in the product manual. Individual fluorochrome-conjugated antibodies should be used to confirm the screening results. The LEGENDScreen(TM) Human Cell Screening (PE) Kit is a convenient and easy-to-use tool to screen cells for a large number of cell surface markers. Its use is beneficial in immunology, stem cell, and cancer research.
