WebAlcohols are also used as fixatives, typically as a cold 70% solution, that fix by denaturing proteins. The benefits here are that they also permeabilize the cell membrane and are suitable for long term storage at 4 o C or -20 o C. Epitopes can however be masked by the denaturing process with alcohol fixation, so optimization may be required ... WebThe Intracellular Fixation & Permeabilization Buffer Set is designed for use in intracellular staining and flow cytometric analysis and has been specially formulated to reduce non-specific staining of fluorochrome-labelled antibodies and increase fluorescence signal to noise ratios.
