Extra Details:: Cytokeratin 19 and its soluble fragment CYFRA have been studied as markers that may correlate with response to therapy and survival in NSCLC. As part of CALGB 30203, a randomized trial of carboplatin/gemcitabine with eicosanoid modulators (celecoxib, zileuton or both) in advanced NSCLC (Edelman JCO 2008), serum CYFRA levels were obtained prior to and during treatment. The objective of this study was to evaluate the possible correlation of CYFRA as a predictive and prognostic marker and to confirm a previous finding that a 27% reduction in CYFRA after one cycle (21 days) of treatment correlated with a longer survival (Vollmer Clin Ca Res, 2003). Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Hybridoma: Sp2/0 myeloma cells with spleen cells from Balb/c mice. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
