The authors of this study aimed to extend a previously developed screening platform to detect the soluble fraction of Axl (sAxl) and EGFR on cellular membranes. The Axion BioSystems Exact (formerly known as the Corning Cell Counter) was used to count cells used to quantify the amount of Axl and EGFR on the cell membranes. All in all, the RAPPID system was expanded to detect Axl in early stages of different types of cancer.
