Characterization of light chain c-terminal extension sequence variant in one bispecific antibody.

Protein modifications such as post-translational modifications (PTMs) and sequence variants (SVs) occur frequently during protein biosynthesis and have received great attention by biopharma industry and regulatory agencies.

2-(Naphthalene-2-thio)-5,8-dimethoxy-1,4-naphthoquinone induces apoptosis via ROS-mediated MAPK, AKT, and STAT3 signaling pathways in HepG2 human hepatocellular carcinoma cells.

1,4-naphthoquinone and its derivatives have attracted widespread attention due to their multiple biological activities, such as induction of cancer cell apoptosis; however, most of these compounds have high cytotoxicity.

Hollow Porous VO/C Nanoscrolls as High-Performance Anodes for Lithium-Ion Batteries.

Novel hollow porous VO/C nanoscrolls are synthesized by an annealing process with the VO/octadecylamine (ODA) nanoscrolls as both vanadium and carbon sources. In the preparation, the VO/ODA nanoscrolls are first achieved by a two-phase solvothermal method using ammonium metavanadat as the precursor. Upon subsequent heating, the intercalated amines between the vanadate layers in the VO/ODA nanoscrolls decompose into gases, which escape from inside the nanoscrolls and leave sufficient pores in the walls.

Synthesis of Mesoporous Single Crystal Co(OH)2 Nanoplate and Its Topotactic Conversion to Dual-Pore Mesoporous Single Crystal Co3O4.

A new class of mesoporous single crystalline (MSC) material, Co(OH)2 nanoplates, is synthesized by a soft template method, and it is topotactically converted to dual-pore MSC Co3O4. Most mesoporous materials derived from the soft template method are reported to be amorphous or polycrystallined; however, in our synthesis, Co(OH)2 seeds grow to form single crystals, with amphiphilic block copolymer F127 colloids as the pore producer. The single-crystalline nature of material can be kept during the conversion from Co(OH)2 to Co3O4, and special dual-pore MSC Co3O4 nanoplates can be obtained.
