Sensitive assay methods are described herein that involve (a) capturing circulating cancer cells (e.g., by any method); (b) extracting mRNA and (c) detecting and quantifying each of full-length androgen receptor (AR-FL), androgen receptor variant 7 (AR-V7), and androgen receptor variant 5,6,7 (AR-V567) in parallel digital droplet PCR assays. Additional methods are described herein for detecting and/or isolating circulating cancer cells by selecting for cells that express transferrin receptor. |
