The graph depicts how mutations affect oligomerization and Indeed, this process is expected to 4 be in competition with protein-protein oligomerization, as evidenced by the molecular dynamics simulations and NMR results reported below. After purification with the Agencourt RNAClean XP kit (Beckman Coulter), cDNA biotinylation was performed as follows. However, we agree that performing a large-scale knockdown experiment that satisfies all the presented requirements can be extremely costly and dependent on the availability of lab resources. Solved Compared to the negative control, what is the The term multimer (/mltmr/) is used in biochemistry for oligomers of proteins that are not covalently bound. To explore the functional role of lncRNAs in LECs or BECs, we performed antisense oligonucleotide-mediated knockdown (ASOKD) of four lncRNA candidates, previously identified as LEC- or BEC-specific lncRNAs, followed by CAGE-Seq [18].
