AccuCheck™ ERF Reference Particles

Catalog number:  A55950

Back to top


AccuCheck ERF Reference Particles are used for standardization and calibration of an intensity unit of fluorescence for flow cytometry analysis. Through the application of the assigned NIST-traceable intensity standard for a given fluorophore, instrument sensitivity and accuracy can be determined, permitting data comparison between flow cytometry instruments. In combination with a biological standard, these particles can also be used to quantify the level of biomarker expression.

AccuCheck ERF Reference Particles features include:
• Lot-specific NIST-traceable ERF values assigned to 26 channels
• Enables fluorescence intensity measurements for instrument accuracy and sensitivity
• Facilitates instrument to instrument data comparison
