Human samples will have 55 kDa and 25 kDa bands, representing the long and short isoforms (FLIP-L, FLIP-S). A third isoform, FLIP-R, was originally identified in Raji cells and migrates at approximately 25 kDa [see Djerbi, M. et al. (2001) Scand. J Immunol. 54, 180-9 (PMID: 11439165; https://www.ncbi.nlm.nih.gov/pubmed/1439165) and Golks A. et al. (2005) J. Biol. Chem. 280, 14507-13 (PMID: 15701649; https://www.ncbi.nlm.nih.gov/pubmed/15701649)]. Mouse FLIP is alternatively spliced, where only the long isoform is generated and, in some rare cases, the FLIP-R isoform may be observed. Frequently, the shorter isoforms undergo proteasomal degradation in mice and are not detected by western blot.

Expert-reviewed interactive pathway providing a current overview of Inhibition of Apoptosis Signaling.
Expert-reviewed interactive pathway providing a current overview of Death Receptor Signaling.
Cell behavior is a tightly regulated process where various signals work together to elicit a specific response. Unraveling these mechanisms allows us to understand how cells are regulated in a normal state.
Organelle markers for immunofluorescence analysis from CST Cell Signaling Technology
Sometimes understanding complex signaling is overwhelming. Try thinking about it as the wiring on a construction site. Maybe that will help!
Cell states can be monitored using markers correlating to your process of interest. These assays and antibodies can be used to detect cell viability, senescence, proliferation, apoptosis, cytotoxicity and oxidative state.
