AcGFP and mCherry Calibration Beads for Flow Cytometry

25 Sept 2014

Commercially-available calibration beads are an indispensable tool when preparing flow cytometers for experiments using fluorescent dyes (e.g. FITC); however, existing fluorescent dye beads are not suitable for instrument calibration if the cells being analyzed express fluorescent proteins. To solve this problem, Takara has developed calibration beads labeled with either the red fluorescent protein mCherry or the green fluorescent protein AcGFP, which has spectral properties almost identical to EGFP. This poster demonstrates that the fluorescent protein Flow Cytometer Calibration Beads are easy to use, and perform equally well on a variety of flow cytometer platforms.

Flow Cytometer Calibration Beads

Flow Cytometer Calibration Beads for AcGFP/EGFP and mCherry. Use these beads to calibrate your flow cytometer prior to analyzing cells that express the AcGFP1 or mCherry fluorescent proteins. The AcGFP Flow Cytometer Calibration Beads allow for easy calibration of any flow cytometer with a 488 nm laser line that excites the green fluorescent proteins AcGFP1 (Aequorea coerulescens GFP) and EGFP. [The AcGFP Flow Cytometer Calibration Beads work for both AcGFP1 and EGFP because their excitation/emission spectra and brightness are almost identical.] The mCherry Flow Cytometer Calibration Beads allow for easy calibration of any flow cytometer with a 561 nm laser line that excites the red fluorescent protein, mCherry.Features: The lowest intensity represents the autoflorescence signal of cells not expressing the fluorescent protein (AcGFP1 or mCherry) The remaining five peaks are evenly distributed over the remaining scale of the green or red fluorescence detection channel Works with any flow cytometer with a 488 nm laser line (AcGFP1) or a 561 nm laser line (mCherry) Applications: Calibrate your flow cytometer prior to analyzing cells expressing AcGFP1 or mCherry fluorescent protein Since the spectral properties and brightness of AcGFP1 and EGFP are very similar, these beads may be used to calibrate flow cytometers prior to using EGFP expressing cells

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms.

Fluorescence can be detected and measured for different purposes using microplate readers, fluorescence microscopes, fluorescence scanners, and flow cytometers.Cell AnalysisThe analysis of cells allows researchers to understand the factors which contribute to cell health and function. These influencing processes can then be predicted and altered, leading to the development of medication and disease treatments.
