polysciences/Polysciences BLI886A Alexa Fluor® 488 Reference Standard Flow cytometry Quality Control

Single-color Fluorescence Reference Standards are labeled with specific fluorochromes to exhibit the same spectral characteristics as labeled cells. Their size approximates that of human lymphocytes (~7-9µm in diameter) and are available in a wide vareity of fluorescent dyes. Fluorescein is also available as a 2µm bead. These standards may be used to QC a specific path of the optical system (laser/filter/PMT), to optimize filter and mirror sets for fluorophores, and to establish a test-specific Target Channel Value for instrument set-up.

Available in three test size volumes:

• A - 20 tests (1ml)
• B - 100 tests (5ml)
• C - 280 tests (2 x 7ml)
