Solution reagent FSP™

antibodyfor flow cytometryIgG

FSP™ CompBeads are state-of-the-art hydrogels that match the scatter of lymphocyte populations and capture mouse, rat, and hamster immunoglobulins. FSP™ CompBeads mimic the fluorescence spectra of stained cells when stained with fluorescent conjugated antibodies. Reactivity: Mouse, rat, hamster IgG and IgM Volume Per Test: 1 drop / test. Each drop contains approximately 1x105 beads. Formulation: FSP™ CompBeads are hydrogels that are suspended in an aqueous solution containing BSA (Origin USA) and packaged in a convenient dropper bottle. The suspension contains approximately equal amounts of positive and negative FSP™ CompBeads. APPLICATION: Fluorescent conjugated antibody stained FSP™ CompBeads are intended as reference controls to match the spectral signature of single staining of real cells. Staining the capture beads yields distinct positive and negative (background fluorescence) fluorescence populations that can be used in calculating spill over matrix for unmix in spectral flow cytometer. For best results, it is recommended to carry an unstained FSP™ CompBeads tube to serve as negative in spillover calculation.
