Vials of high-quality, methanol-free formaldehyde, a general IHC fixative and reversible amine-crosslinking agent for protein and nucleic acid samples.
Microspheres have diameters close to those of many stained cells, providing fluorescence microscopists with intensity references for generating calibration curves and evaluating instrument performance
Provides external reference for comparing images collected with different optics, on different instruments and in different laboratories, as well as for monitoring routine day-to-day variations in instrumental performance
