Quantum MESF and Simply Cellular
Introducing Quantum™ MESF and Quantum™ Simply Cellular® beads from Bangs Laboratories, now available from 2BScientific as external standards. They help researchers standardise the fluorescence intensity units that flow cytometers report using different software platforms. These beads are labelled with the same fluorochromes that are used for cell labeling so that they give a synchronous response to environmental conditions. The easy use of these beads is a plus for researchers as they can run them alongside samples on the same day with identical PMT and compensation settings in order to establish calibration curves simply and effectively. This calibration ensures determination of fluorescence signal expression in cell populations accurately— helping reproducibility while simplifying workflow by guaranteeing that experiments include consistent and reliable fluorescence measurements which contribute towards advanced precision and consistency in research outcomes.

SureCount ™ PCS (Particulate Contamination Standard) – Contamination
Global pharmacopoeia standards for pharmaceutical, ophthalmic, parenteral, and therapeutic protein injections and/or solutions require that these solutions be tested for contaminating particles. To demonstrate that these tests meet the standards, the machines need to be calibrated to ensure that they are meeting the required levels of detection. The provision of standard solutions that can be used for these instrument calibration checks and evaluating the cleaning procedures of the single-use consumables is therefore of critical importance to Quality Control departments.
Bang’s Laboratories has recently launched SureCount™ PCS-Contamination beads for customers needing to meet USP<787>, USP<788>, USP<789>, ASTM E3230-20, European Pharmacopoeia 2.9.19 and more international standards. The 15.0 ± 0.2 µm beads are supplied at 3800 particles/mL ± 15% in water. Each lot is sized using a NIST-calibrated stage micrometer with digital processing. Particle counts are verified using the Coulter method.
Bang’s Labs are an original manufacturer of these standards, which offers an advantage to established QC departments in surety that their supply is not dependent on a single manufacturer of their current standards, as well as the option of a price advantage for new QC protocols written.
Bang’s Labs SureCount PCS can be supplied with or without the SureCount™ buffer solution (blanks).

QUANTUM™ SIMPLY CELLULAR®
Quantum™ Simply Cellular® (QSC) kits consist of five microsphere populations, each approximately 7-9µm in diameter. These include one blank population and four labelled populations with increasing amounts of antibody. Each labelled population binds a specific number of monoclonal antibodies, corresponding to its Antibody Binding Capacity (ABC) value. Researchers can additionally label QSC beads using the same antibodies used for staining cells.
To assist with determining cell expression levels and evaluating instrument linearity and detection threshold, each kit includes a free QuickCal® analysis template. Quantum™ Simply Cellular® kits are available in three sizes: A (20 tests), B (100 tests), and C (280 tests).

QUANTUM™ MESF
Quantum™ MESF kits include one blank population and four fluorescent microsphere populations labelled with varying amounts of Alexa Fluor® 488, Alexa Fluor® 647, APC, or R-PE or five fluorescent microspheres for FITC. The fluorescence intensity is measured in Molecules of Soluble Fluorochrome (MESF) units, which are allocated by directly comparing fluorescence measurements from pure fluorochrome solutions with those from surface-labelled microspheres using the same fluorochrome.
Each kit comes with a free QuickCal® analysis template to assist in determining cell expression levels and evaluating instrument linearity and detection threshold. Quantum™ MESF kits are available in three sizes: 20 tests, 100 tests and 280 tests.
