摘要:
The invention relates to a mechanical digging device (1) with a handle-like support (2), comprising a digging part (4) near its bottom end (3) and two grip arms (6) on its upper end (5), a support part (7) embodied on the bottom end (3) of said support (2) and a rotating device mounted on the support (2) and connected to the digging part (4) for laterally tilting the material on the digging part (4). According to the invention, the rotating device (9) penetrates the support (2) and the longitudinal axis (11) of the rotating device (9) extends parallel to the longitudinal axis of the digging part (4).
摘要:
The invention relates to combinations of a carrier and a complex, which consists of a nucleic-acid molecule and a copolymer. Said copolymer consists of an amphiphilic polymer, preferably polyethylene glycol and a charged effector molecule, in particular, a peptide or peptide derivative. The invention also relates to the use of the combinations for transferring nucleic acid molecules into cells.
