ICAD, Recombinant Human (DFF 1, DFF 45, DFF alpha, DFF1, DFF35, DFF45, DFFA, DNA Fragmentation Factor alpha subunit, Inhibitor of Caspase Activated DNase)

DNA fragmentation factor (DFF) is a heterodimeric protein of 40-kD (DFFB) and 45-kD (DFFA) subunits. DFFA, also known as DNA fragmentation factor subunit alpha, is the substrate for caspase-3 and triggers DNA fragmentation during apoptosis. DFF becomes activated when DFFA is cleaved by caspase-3. The cleaved fragments of DFFA dissociate from DFFB, the active component of DFF. DFFB has been found to trigger both DNA fragmentation and chromatin condensation during apoptosis. Recombinant DFFA protein , expressed in E. coli and purified by using conventional chromatography techniques.\n\nSource:\nRecombinant corresponding to human DFFA, aa1-331, His-tagged, expressed in E. coli\n\nMolecular Weight: \n~38.7kD\n\nAA Sequence:\nMGSSHHHHHH SSGLVPRGSH MEVTGDAGVP ESGEIRTLKP CLLRRNYSRE QHGVAASCLE DLRSKACDIL AIDKSLTPVT LVLAEDGTIV DDDDYFLCLP SNTKFVALAS NEKWAYNNSD GGTAWISQES FDVDETDSGA GLKWKNVARQ LKEDLSSIIL LSEEDLQMLV DAPCSDLAQE LRQSCATVQR LQHTLQQVLD QREEVRQSKQ LLQLYLQALE KEGSLLSKQE ESKAAFGEEV DAVDTGISRE TSSDVALASH ILTALREKQA PELSLSSQDL ELVTKEDPKA LAVALNWDIK KTETVQEACE WELALRLQQT QSLHSLRSIS ASKASPPGDL QNPKRARQDP T\n\nStorage and Stability:\nAliquot to avoid repeated freezing and thawing and freeze at -70 degrees C.
