Expression of many pro-inflammatory cytokines is controlled by the NF-κB signaling pathway. NF-κB is induced by LPS through activation of TLR4. Melanins extracted from fungal, plant and human sources modulate cytokine production and activate NF-κB pathway. We showed that a herbal melanin (HM) from Nigella sativa L. modulates cytokine production and suggested it as a ligand for TLR4. In this study...
A novel, cartridge-based procedure for the efficient and irreversible detritylation of oligonucleotides is reported. This method, combined with a process for the elimination of depurinated fragments produces, in a highly parallel fashion, oligonucleotides with better purity than those traditionally obtained using reversed-phase high-performance liquid chromotography purification. Our combined detritylation...
